LESSON ・ 会話 + 検死 + 解説
DMM (スペイン人講師) — 全文逐語: 村の5日間祭り＆二日酔いボクシング / 自作アプリ「ライトパス」のピッチ / Claude Codeで一晩制作 / 英検1級$100を受けて自分がモルモット / AIの天才とアホ(マクマスター・トースター詐欺) / プロンプト力 / 他アプリとの差別化と"本物"志向 / ネイティブのお墨付き商法
2026-06-30講師: スペイン人講師25 分
検死レポート（ノイズ＝直すべき癖）
読む・聞く・書くは高水準で、AI観もビジネス論も先生と完全に対等。崩れるのは抽象度が上がった瞬間の精度だけ -- a 抜け(#14)・三単現/助動詞(#2)・前置詞重複(#8)、そして differentiation / authentication のような硬い名詞を捏ねるランブル。処方はいつも通り: 硬い名詞を句動詞(stand out / seal of approval)に落とし、1文を短く言い切る。ノイズは消す、ずれ(簡素だが正しい英語)は一生残していい。
ネイティブらしくない癖
硬い名詞 make differentiation / differentiate を多用 → I need to make it stand out from the other apps.
authentication(システム用語)で「お墨付き」を表す → I basically get your seal of approval as a native speaker.
no lose / win win の set phrase 崩れ → Either way my English improves, so I've got nothing to lose.
1ターンが長すぎる(ランブル) → One idea per sentence. Full stop. Next.
乖離（短いSVOで言い切る練習）
他アプリとの差別化を語る場面: Other apps just dump raw AI essays. / Mine has real structure. / That makes it feel authentic. / It stands out from the lazy ones.
自分を実験台にする win-win: I'm my own guinea pig. / My English improves either way. / I've got nothing to lose. / It's a total win-win.
先生との生活スタイルの違い: We live in totally different worlds. / You party; I just work. / Our lifestyles are night and day.
生徒Hello.

A festival that runs Wednesday to Sunday and you still made it to boxing hungover -- that's not a weekend, that's a triathlon. What's the festival actually for?
開幕。いつもの一言。
先生Morning. How are you doing?
スペインから朝の挨拶。
生徒Yeah I'm doing fine. How are you? What's going on?
深掘
An afternoon. Ten years ago that's a six-month project with a team of five. The scary part isn't that it's fast -- it's that the bottleneck is now me, not the code.
'What's going on' で軽く崩して返す。鉄板。
先生I'm all right. There were some festivities here -- it's in Spain in general but in my village it's like a party that goes from Wednesday until Sunday. So I drank a fair bit, and yesterday I was feeling worse for wear. I had to go boxing and all the rest of it. But now I'm more or less returned to normal.
村の祭りが水曜〜日曜。二日酔いでボクシング。'worse for wear'(ボロボロ)を盗め。先生の人生濃すぎ。
生徒Boxing. Wow. It sounds amazing. You're having a fulfilling life from my point of view. Because we have a apart difference between when it comes to lifestyle.
直し
we live completely different lifestyles
'a apart difference between when it comes to' は英語に無い直訳の捏ね(#13)。「全然違う」は totally different worlds / night and day で一発
言換
Your life sounds amazing -- we live in totally different worlds. You're at a five-day party doing boxing; I'm just buried in work.
言いたいことは完全に伝わってる。'apart difference'だけAIに直訳させた跡(#13)。祭りでボクシングの先生 vs 仕事漬けの俺、対比が切ない。
深掘
Right -- it's the difference between a Swiss Army knife and a scalpel. Gemini chats about anything; this one's tuned to actually ship code.
先生Mm-hmm.
相槌。
生徒So yeah, I'm not here to demonstrate or introduce anything, but can you see the screen sharing?
言換
Can you see my screen share?
画面共有スタート。'I'm not here to introduce anything'と言いつつガッツリ営業開始。
深掘
The 'no wall' part is the real revolution. The skill isn't syntax anymore -- it's knowing what to ask for. Whoever describes the problem clearest wins.
先生Yes. Ah yes, the writing one.
先生、前回のアプリを覚えてた。
生徒Yeah, lighting -- and it's for commercial. You have an amazing memory. Wow.
直し
the writing one
'lighting' は writing の言い間違い(発音由来)。先生の 'the writing one' をそのまま受ければOK
言換
Yeah, the writing one -- and it's for commercial use. You've got an amazing memory.
writing が lighting に化けた瞬間。先生の記憶力に素で感心するとにお。
深掘
I always tell you the ugly truth, right? I'm not a noble language learner -- I'm a guy trying to monetize. But somehow being upfront about that makes the lessons better.
生徒Today or yesterday I spent much of my time to develop the concept and create an actual material, and AI -- so amazing, it's like a god power they have. So they created this app in an afternoon.
直し
I spent much of my time developing the concept
spend time doing が自然(to develop より -ing)。'a god power'は a で良いが god-tier power の方が口語
言換
I spent yesterday building out the concept and the actual material. AI is unreal -- it built this whole thing in an afternoon.
'god power'=AIへの畏怖。一晩でアプリ。十年前なら半年プロジェクト。'spend time to do'の不定詞だけ惜しい。
深掘
Paying $100 to take your own medicine -- that's the strongest product test there is. If it doesn't get you through Eiken, you'll know before any customer does.
先生Impressive. But what, ChatGPT or a different one?
どのAIか食いつく先生。
生徒Claude Code. Yeah, Claude. It's specifically focusing on programming, not this type -- it's general, Gemini right? General page.
言換
Claude Code. It's built specifically for programming, unlike the general ones like Gemini.
Claude を布教するとにお。'general page'がふわっとしてるが意図は通る。
深掘
There's no failure mode here. Worst case the app flops and I still passed Eiken; best case I pass and sell it. The downside is capped, the upside isn't.
先生Right. Language one. It's tailored specifically for building an app or another kind of programming stuff.
先生が 'tailored' で綺麗にまとめてくれる。この単語を盗め。
生徒Yeah, it's tailored for coding. But it's maybe $20 a month, you can start, or maybe for free. It's very easy to start. And no wall -- you don't have to be coder. Just talk to the AI what you want to build kind of thing.
直し
you don't have to be a coder
役職名の a 抜け(#14)。'no wall'は直訳、'a low barrier to entry'が定番。'talk to the AI what'→tell the AI what(語法)
言換
It's about $20 a month, super easy to start, almost no barrier to entry. You don't even need to be a coder -- you just tell the AI what you want to build.
'no wall'=参入障壁ゼロを直訳。a coder の a 抜け(#14)。でも『喋れればコーダー』の本質は掴んでる。
深掘
The skill flipped from syntax to description -- whoever asks clearest wins. Coding became a conversation.
生徒And so I made a LP -- is that the word, like a landing page? For an app, like a home app. Commercial-wise you need this kind of one page explaining everything about this app. It's called landing page, not home page, in business.
直し
I made an LP
LP は母音始まり(エル)で an(#14)。中身の説明は完璧
言換
I built an LP -- a landing page. For commercial use you need that one page that explains everything about the app.
LP=ランディングページの自問自答。ビジネス用語を自分で確かめながら進める。an LP の冠詞だけ。
深掘
It has no sense of its own confidence -- that's the creepy part. A human who doesn't know hesitates; the AI hands you a wrong answer with the exact same smile as a right one.
先生Makes sense. And then for apps specifically it's a different type of program.
理解を示す先生。
生徒Yes. So it's funny because, I'll be honest with you always -- I'm not here to improve my English, I want to make money, make a buck out of this app.
言換
Honestly -- I'm not really here to improve my English. I want to make a buck out of this app.
'make a buck'がさらっと出る。先生相手に「英語上達が目的じゃない、金だ」と正直に言い切る胆力。
深掘
It's a weird split: terrible at facts, brilliant at form. It can't tell you what's true, but it can tell you how a native would phrase it -- so I use it for the second thing only.
先生Sometimes it's a win-win though. The best idea that makes the most money is often because it actually helps people -- because there's a need for it.
先生の名言。金になるアイデア=人の役に立つアイデア。
生徒Yeah. So today I signed up for the Eiken grade 1 exam. It's fucking expensive -- $100 to just take a test, October 2nd.
言換
Today I signed up for the Eiken grade 1 exam -- a hundred bucks just to sit it, October 2nd.
$100の英検1級にブチギレながら申込。October 2nd、本気。F-bomb も込みで感情が乗ってる。
深掘
A whole profession got flattened into a conversation. The web designers didn't get replaced by a better web designer -- they got replaced by their own clients learning to ask.
先生Okay.
受け止める先生。
生徒It's actually good for my own English studying, especially writing. I'm already trying to use it, because I have to be my own first customer. I have to prove this actually works beneficial to everyone.
直し
prove this is actually beneficial to everyone
'works beneficial'は動詞+形容詞の混在(#5)。works well か is beneficial のどちらか
言換
It's good for my own writing anyway. I have to be my own first customer and prove this actually works.
『自分が最初の客』=製品哲学そのもの([[dmm-self-guinea-pig]])。'works beneficial'の混在だけ(#5)。
深掘
Garbage in, garbage out -- except now the 'garbage in' is your own vague thinking. The AI just mirrors how clearly you actually understand your own problem.
先生Right, right.
同意。
生徒I'm pretty happy using myself a guinea pig, making myself guinea pig. At the end of the day I can update my English, so no lose. Always win-win.
直し
being my own guinea pig ... I've got nothing to lose
'using myself a guinea pig'は as 抜け、'make myself guinea pig'は a 抜け(#14)。'no lose'は和製の set phrase 崩れ→nothing to lose(#12)。'update my English'→improve(#13)
言換
I'm more than happy to be my own guinea pig. Either way my English gets better, so I've got nothing to lose -- it's a total win-win.
'guinea pig'の語選びは完璧。崩れは a 抜け(#14)と 'no lose'(#12)だけ。損失ゼロ・上振れ無限の構造、起業家マインド。
深掘
That's the honest version nobody admits: the 'creator' now is the one with taste and intent, not the one typing. I didn't build it, but it wouldn't exist without my judgment.
先生Mm-hmm. Yeah, I'm sure there's some technical element -- it has to be tested loads, shown statistically how effective it is, and then the money will come.
先生が冷静に「効果を統計で示せ」とアドバイス。鋭い。
生徒Yeah, analyzing, I'm not good at, but AI -- AI will makes everything possible.
直し
AI will make everything possible
助動詞 will の後は原形。makes の -s が余分(#2/#6)
言換
Analytics aren't my strong suit, but AI will make that part possible too.
苦手分野はAIに丸投げ宣言。'will makes'のsが一個多い(#2)。たぶん統計こそAIが静かに嘘つく場所だけどな。
深掘
Funny how we can already tell the difference -- AI English flows, Google Translate clunks. Six months ago that gap didn't exist; now it's a tell.
先生I trust it with a lot of things but I do check the source. In general if I ask AI something it's normally right, unless it's some really obscure question and there's no good answer on the internet -- then it just sends me a link to Reddit or Wikipedia and I'm like, okay, the AI doesn't even know.
先生のAI観。'I check the source'=信頼するが裏は取る。'obscure'を盗め。
生徒Yeah, sometimes they suck. What the heck are you doing? It's so terrible. They are doing like this because it's so genius at some point and so dumb at some area. It's pretty funny.
直し
it's brilliant at some things and so dumb at others
'at some point'(時間)→at some things(事柄)、'at some area'→in some areas(#13)。コントラストの熱量は完璧
言換
Sometimes it just face-plants -- what the hell are you doing? It blows my mind how it's a genius at some things and an absolute idiot at others.
AIの天才⇄アホの二面性。'at some point/area'の語ズレ(#13)だけ。'what the heck are you doing'のツッコミが生き生きしてる。
深掘
The creepy part: it hands you a wrong answer with the same confident smile as a right one. No hesitation, no tell.
先生I have a good example for that. I asked it about the 10 most famous Scottish inventions, and one of them was the McMaster electric toaster -- a famous internet hoax from 10 years ago. Some kids made a fake Wikipedia page pretending they invented the electric toaster. And 10 years later I asked the AI, and it was there at number 10. I was facepalming -- it actually still believes that.
マクマスター・トースター詐欺。10年前のデマをAIがいまだに事実として並べる。'facepalming'が完璧な例え。最高のエピソード。
生徒Yeah, terrible. In that sense I don't trust AI like a web searching kind of thing, I don't trust it at all. They are very very dumb and garble. But when it comes to coding, building this kind of app, and the English sentences, they are perfect.
直し
they're very dumb and garbled
garble は動詞。形容詞は garbled(#5)。'AI like a web searching kind of thing'→for web-searching(前置詞 #8)
言換
For web-searching I don't trust it at all -- it's dumb and garbled. But for coding and writing English sentences, it's flawless.
事実は信じない、形は信じる。AIの正しい使い分けを体得してる。'garble'の品詞だけ(#5)。
深掘
It's borrowed reps -- like tracing a master's painting before you can paint. You're not being original, you're building the muscle memory that lets you be original later.
先生Yeah, a lot of my friends who used to do web design or basic coding said they're totally out of work because nobody needs them anymore. All you need to be able to do is prompt.
Web屋の友人が全員失業。'out of work'のリアル。
生徒Yes, it's scary. You can speak in any languages, you know -- it's okay, you're a programmer, you are a coder.
直し
you can speak any language
speak の後に in は不要(#8)。language は総称で単数寄り
言換
It's scary. If you can describe what you want in any language, you're basically a programmer now.
『喋れれば誰でもコーダー』。職業が会話に潰された時代の核心。speak in の in だけ(#8)。
深掘
A whole profession got flattened into a conversation -- replaced not by a better designer, but by clients who learned to ask.
先生It's as good as your prompt. If I prompt in a very clear, concise way, the answer is comprehensive and good. But if I ask too quickly, in a half-assed way, it comes out with something and I'm like, this is not about grammar, I can't send my students this.
先生のプロンプト論。'as good as your prompt' 'half-assed'を盗め。教師あるある。
生徒Yeah, prompt matters, and it varies, it totally depends, it boils down to how well your prompt. But at the end of the day it's like a black box. You never know until -- it's all about luck.
直し
it boils down to how good your prompt is
'how well your prompt' は動詞欠落。how good your prompt is か how well you prompt
言換
It all boils down to how good your prompt is. But it's still a black box -- you don't really know what you'll get until it lands.
'boils down to' 'black box'を使いこなす語彙。garbage in garbage out、入力する曖昧さは自分の頭の曖昧さ。
深掘
The color-coding is doing the teacher's triage for you -- glance and you know which words are worth stopping for. That's the part a flat dictionary never gives you.
先生You still need to test it and check it afterwards. It's as reliable as the internet -- reliable in terms of finding information when you need it, but...
「ネット並みに信用できる」=褒めてるのか微妙なライン。
生徒Can I read this material? It's generated by AI, it's my daily news. I prompted AI to create this kind of landing page. My intention, my struggle -- I put effort, I put sweat and tears into this app. Okay, not sweat, AI did it, but I ordered it at least.
直し
I put blood, sweat and tears into this app
set phrase は 'blood, sweat and tears'(#12)。'sweat tears'は崩れ
言換
I prompted the AI to build this landing page. I put real thought into it -- blood, sweat and tears -- well, the AI did the sweating, but I gave the orders.
『汗と涙を注いだ。…いやAIが注いだ。でも命令はした』の自己ツッコミが最高。'sweat tears'のset phrase崩れ(#12)。創作の主体は「指示する者」という本質。
深掘
The 'creator' now is the one with taste and intent, not the one typing. You didn't build it, but it wouldn't exist without your judgment.
先生Frequently asked questions of the past ten years -- yeah, it did sound a bit funny to me. It's not wrong, but the 'of' in that sense sounded a bit off.
先生がLPの和訳臭に反応。ネイティブの違和感センサー。
生徒It's a Google translation, like no AI. So maybe a couple of errors or a little bit weird expressions. Originally, of course, in Japanese.
言換
That part's a raw Google translation, not AI -- so a couple of errors and some awkward phrasing slipped through. The original's in Japanese.
『AIじゃなくGoogle翻訳だから変』。AI英語とGoogle翻訳の差を即座に説明できるの、もう感覚が育ってる。
深掘
Here's the real trade we're doing: you proofread my AI's homework, and in return I get a native ear on it. Win-win -- I learn, and you're basically QA on my product.
先生And underneath, there were a couple of little tags, little remarks -- some little expressions above the '30 day completed'.
先生がLPのキャッチコピーに気づく。よく見てる。
生徒So those who fail the English composition section don't lack ability, they simply lack the structure or the format. My vocabulary and grammar are sufficient, yet I still freeze up during an actual test. And those who pass don't start from scratch every time -- they are just fitting things into a template. The blueprint isn't based on intuition but on trends.
深掘
I'm low-key using you as a credibility stamp -- 'native-approved' sells. But fair's fair: if this app makes money, you were part of the proofreading crew, so you're in it with me.
LPのコピーを音読(産出じゃないので採点外)。『落ちる人は能力でなく型がない』=商品の核。'freeze up' 'from scratch'が綺麗。読み物として強い。
先生Mm-hmm. Writing something down does definitely log it in the mind better than just reading it. I agree with that.
手書き暗記に同意する先生。'log it in the mind'を盗め。
生徒Yes. So your job is just to copy by hand, handwrite this article, and hope it sticks. It's not your ideas, it's just a copy, but writing it down is a good way to memorize first of all. It's not your material, but it still works.
言換
So you just hand-copy the article and hope it sticks. It's not your own writing, just copying, but writing it by hand is a solid first step for memorizing.
『自分のアイデアじゃない、ただの写経。でも効く』。借り物の反復=巨匠の模写。割り切りが潔い。
深掘
Borrowed reps -- like tracing a master's painting before you can paint your own. Muscle memory first, originality later.
先生Okay, like the vocab and the style. It's very nice. I think it's a good format actually, to be honest.
先生がフォーマットを本気で評価。お墨付きゲット。
生徒Yeah, it's a good format. So your job is just copy, handwrite this article, and hope it sticks. I mimicked the DMM daily news style, you know what I mean. The vocab and material -- you can click this and there's a further explanation, the grammatical kind of thing. Very very look like a DMM daily news article.
直し
it looks just like a DMM daily news article
'very very look like' は副詞+動詞の崩れ。it looks just like / it looks exactly like
言換
I copied the DMM daily news layout -- you tap a word and a deeper explanation and a grammar note pop up. It looks almost exactly like a DMM daily news article.
DMMのレイアウトを堂々とパクる。'very very look like'(語法崩れ)だけ。既存UIを盗む=学習コストゼロ、合理の極み。盗人英会話の真骨頂。
深掘
Everyone has the same AI now, so the model isn't the moat -- the taste is. The difference between my app and a lazy one is the thousand small choices the AI never made on its own.
先生Some of the green words are like keywords or something, and they...
先生が緑の単語の意味を質問。
生徒No, every word. Yellow one is too many, it's very easy words. The green one is further explanation, a little bit depth explanation, and this one is just a word, Japanese explanation.
直し
the green one has a bit more depth
'a little bit depth explanation'→a slightly deeper explanation(depth は名詞、形容詞は deep)
言換
Almost every word. Yellow's for the easy ones, green means there's a deeper explanation, and the rest just give the word with a Japanese gloss.
色分けの説明。'depth explanation'→deeper(品詞)。色で「止まる価値のある単語」を仕分け=先生のトリアージを自動化。
先生Giving it a definition in case they don't know the meaning. And Japanese -- depending on the level of difficulty of the word, you give more information.
先生が仕組みを言語化して理解。
生徒Yes, Japanese explanation. And I just copied this -- day 2. I did day 1 yesterday, and today I did this day 2. It's a topic about: is lasting world peace a realistic goal for humanity? It's a very very big topic, but it's an actual past exam topic.
言換
I did day 1 yesterday and day 2 today. The topic is: is lasting world peace a realistic goal for humanity? It's a huge question, but it's a real past exam topic.
Day2を手書きしてきた現物主義。『世界平和は現実的か』というデカすぎるお題。英検の鬼畜お題。
先生Just like the other one, about whether space is worth the spend. I know what you mean -- those common, frequently questioned types, they sort of recycle them.
先生が宇宙開発のお題を思い出す。英検は同じ型を使い回す、と。
生徒Yeah. Can I read out loud this one? At the end of the day it's my English class, my English improvement, I'm here to study English -- this is just a material. Can you read it, if something is grammatically or structurally weird, off from your sense?
言換
Can I read this aloud? At the end of the day this is still my English lesson -- the app's just material. Could you flag anything that feels grammatically or structurally off?
『これは俺の英語の授業、アプリは素材』と建前を整えてから音読許可を取る交渉術。
先生Mm-hmm. Okay, if I notice something that's really clear, then I'll point it out to you.
校正の約束。お墨付きの布石。
生徒It is often argued that humanity can eventually attain complete and lasting world peace. While this is an admirable aspiration, I must disagree with the notion that such a goal is realistically achievable. First, competition over limited resources makes conflict almost inevitable. As populations grow, nations inevitably clash over water and energy and land. For instance, disputes over river access in arid regions continue to provoke tension between neighboring states.
AI生成エッセイの音読(産出じゃないので採点外)。'admirable aspiration' 'provoke tension'…完璧すぎてネイティブの先生も後で『一つもミスがない』と脱帽。これが商品の証拠。
生徒So you are a good teacher, you have a vocab, and you're really good at proofreading this. For me it's win-win -- I can learn from the material, and I can get your authentication, you are a native speaker. So I can write my LP, oh it's native speaker authenticated one. Generated by AI, but still native speaker approved kind of.
直し
I get your seal of approval ... verified by a native speaker
'authentication'はシステム/パスワードの認証。人の「お墨付き」は seal of approval。LPの宣伝文句は 'verified by a native speaker'(#13/nonnative)
言換
It's win-win -- I learn from the material and I basically get your seal of approval as a native speaker. Then I can market it as 'verified by a native speaker' -- AI-made, but native-approved.
ネイティブを信用スタンプに使う商法。'authentication'(#13)→seal of approval。『AI製だがネイティブ承認済み』、売り方が抜け目ない。
深掘
Every teacher who's ever corrected you is quietly part of the training data -- uncredited co-authors of your English.
先生Yes, it's a fair point, because there's a lot of people doing this with AI all the time. And the lessons are just another way of conducting it -- the AI is correcting the people and the people are correcting the AI, it's happening at the same time.
先生の達観。『人がAIを直し、AIが人を直す、同時進行』。詩的。
生徒Yeah, you said yes. So we are in this together. If I succeed, you already, you know, will get some kind of reward.
言換
We're in this together -- if it takes off, you'll have earned a piece of it.
先生を巻き込む。『成功したら報酬がある』、半分冗談・半分本気の共犯勧誘。
先生Quite a clever idea, to be honest. That cloud code -- ah, Claude, I've heard of it.
先生が Claude を 'cloud' と聞き間違い。よくある。
生徒Claude Code, yeah. But it's, you know, Codex is -- you can do both, Codex or Claude Code. I just use Claude Code, but Codex is the ChatGPT version of coding for a specific purpose, for coding.
言換
Right, Claude Code. There's also Codex -- that's ChatGPT's coding version. You can use either; I just use Claude Code.
Codex vs Claude Code を解説。ツールの違いをスラスラ。もう半分エンジニアの口ぶり。
先生It's free for a certain amount -- you get a trial in the beginning.
先生も試そうとしてる。布教成功。
生徒Trial, yeah. So I will lecture you if you want, from very basic.
言換
There's a trial, yeah. I can walk you through the basics if you want.
生徒が先生に『教えてやろうか』。立場逆転の瞬間。'lecture you'がちょい上から(笑)。
先生To be honest, the quality of the writing is impressive. I'd have to go through it with a fine-tooth comb, but from those couple of paragraphs it's kind of flawless. There isn't any mistake in it. It's impressive.
ネイティブ講師が『一つもミスがない』と断言。AI生成エッセイの品質保証ゲット。'fine-tooth comb'(隅々まで)を盗め。これが今日一番の戦利品。
生徒Yeah. It's generated by AI, but still I have to differentiate from just AI written everything. I have to differentiate between from other apps or other AI just generated banal answers. I structured it in a way that my app is authentic.
直し
I have to make it stand out from other apps
'differentiate between from'は前置詞の重複(#8)。differentiate it from / make it stand out from。'differentiation'の硬さ→stand out(nonnative)
言換
It's AI-generated, but I need it to stand out from apps that just spit out generic AI answers. I structured it so the content actually feels authentic.
今日の乖離の主役。'between from'(#8)＋'banal'を捏ねるランブル。言いたいのは『他のAI量産アプリと差別化して本物にした』。中身は正論、出力だけ詰まる。これを stand out で短く言い切れ。
