Lingotchi

Your day becomes your textbook.

Lingotchi is a language-learning app: AI reads your short daily journal, pulls out the expressions you were reaching for, and puts you straight into conversation practice. It covers Spanish (Tacotchi) and English (Burgertchi), switchable any time inside the app, and your character grows with every session.

An account is required. You can sign in with an email address or a Google account; when you sign in with Google we only receive your name and email address.

WHY

The material is already inside you.

Lingotchi doesn't start from "the next page of the vocabulary book." It starts from what you couldn't say today. Four things we care about.

1. The moment you got stuck is the material

The line you couldn't produce sticks far better than any syllabus word. So it all starts with your journal.

2. Quitting isn't a willpower problem

If nothing happens when you skip today, people skip. So someone is waiting for you today.

3. An honest character

Show up and it grows; slack off and it rots. A little cruel โ€” and exactly why you come back.

4. Your journal stays yours

Honest writing is the whole point. Journal text is unreadable to anyone but you โ€” including us.

Not the next drill โ€”
learning that starts from your own words.

HOW IT WORKS

Write it โ†’ find it โ†’ say it.

One loop takes 5 to 10 minutes. You just repeat these three every day.

STEP 1๐Ÿ““ Write a journal

What happened today, in the language you're learning. Where the words run out, switch to your own language โ€” the gap is the point.

๐ŸŒฎ IN SPANISH
Hoy fui a una cafeterรญa. I wanted to order the new item on the menu but had no idea how to say itโ€ฆ
๐Ÿ” IN ENGLISH
I had a meeting today. I wanted to say I'd check internally and reply later, but nothing came outโ€ฆ
STEP 2โœจ AI pulls out the expressions

Four or five phrases that would have said what you meant. Spanish comes with the conjugation that fits your context; English comes with alternatives and how formal each one sounds.

๐ŸŒฎ SPANISH
pedir
to order, to ask for
quiero pedir I want to order / pedรญ I ordered
๐Ÿ” ENGLISH
get back to you
reply once you've checked
circle back casual / follow up formal
STEP 3๐Ÿ’ฌ Use them in conversation

A single-session chat where AI builds a flow that naturally calls for those phrases. Beginners arrange chips; everyone else types freely. Corrections come on their own ๐Ÿ“ line, separate from the conversation.

๐Ÿ” IN ENGLISH
So, can you commit to that deadline?
Let me get back to you on that tomorrow.
Sounds good. I'll wait for your update.๐Ÿ“ Nailed it โ€” "by tomorrow" would pin the deadline down
GROWTH & DECAY

Learn and it grows. Skip and it rots.

Journals and conversation practice earn points, and your character levels up. Levels go to 100. At Lv.10, 20, 30 and 40 you get cards that widen what you learn.

Go quiet for too long, and it rots. ๐Ÿชฐ

When the freshness gauge hits zero you get mold and flies. It's never fatal โ€” you can always start again. And on a day when your streak is about to break, a saved "preserve" covers one day for you. The character takes the hit so you have a reason to come back.

DETAILS

Everything aimed at actually using it.

๐ŸงฉOutput at your level

Beginners build sentences by arranging chips; intermediate and advanced type freely. Pick the load that fits today.

๐Ÿ“–Conjugations and alternatives in context

Spanish shows the form your sentence actually needs ("I worked yesterday" = trabajรฉ). English shows which wording you can send to your boss, with tone labels.

๐ŸŽฅSee natives actually say it

One tap jumps to clips where your phrase is spoken for real. Proof it isn't textbook-only.

๐Ÿ’ผBusiness role-play

In English you can register your real manager, teammate or client and rehearse tomorrow's meeting. Anything you paste in is never stored.

๐ŸŒExplanations in English, Japanese, or both

Switch the language of meanings, translations and corrections whenever you like.

๐Ÿ”Deep-dive requests

Send a theme โ€” "ordering at a cafรฉ", "pushing back on price" โ€” and get a custom expression set on the spot.

FAQ

Frequently asked questions

What does the app actually do?
You write a short daily journal, and AI extracts 4โ€“5 expressions that would have let you say what you meant. You then go straight into conversation practice and use those expressions for real. Your character grows with what you learn.
Can I do both Spanish and English?
Yes. Switch any time inside the app โ€” each language keeps its own character, level, phrasebook and journals, so nothing is lost when you move between them. One account and one subscription covers both.
How much does it cost? Can I try it free?
The first 7 days are completely free, no credit card. After that it's ยฅ980 JPY per month (about $6) or ยฅ9,800 per year (about $60 โ€” two months free). One subscription covers every language. See Pricing.
What if I can barely write in that language yet?
That's fine. Mix in your own language wherever you get stuck โ€” the gap between what you meant and what you managed is exactly what becomes your material. In beginner mode you can build replies by arranging chips.
Can anyone read my journal?
No. Journal text is unreadable to anyone but you at the database access-control level, including us. In classroom use, teachers only see statistics like streaks.
Is cancelling easy?
Yes. Cancel any time from your account page in the app (it opens the Stripe portal). You keep access until the period you already paid for ends.
Will more languages be added?
A Chinese version (Pandatchi ๐Ÿผ) is in development. It will work with the same account and the same subscription.
