One connection · four ways to use it

Not a language app. A tutor for everything.

One tutor for everything you're learning. Sit down with it for a real session, or let it work quietly alongside your day.

Learn a language

It starts with what you already know. Words that look right but aren't get caught before they stick.

SpanishFrenchGermanItalianJapaneseMandarinArabicEnglish

More languages on the way.

Learn a topic

Any subject builds into a real path, taught forward from what you already know.

Practice while you work

Keep it connected in the AI you already work in, and it slips a little practice into what you're doing.

Immerse Yourself

The topic leads, and your new language weaves through it at your level.

How it works

No new app. One address, pasted once.

Add the connector

In a supported AI client (Claude, ChatGPT, Claude Code, or VS Code), paste one address into its connectors panel and sign in right there. No separate signup, no forms; you keep your AI.

Say what you want to learn

Give the agent as much context as you want to customize the path. It begins by finding where you already are, and every session updates your progress for the next.

Add it to your AI

Claude, ChatGPT, Claude Code, and VS Code can sign in today; the rest join as they adopt the new sign-in standard. The address is the same everywhere.

The second session

Your tutor reads your path, and knows exactly where you stopped.

Your AI's memory keeps notes about you. A tutor keeps a curriculum: what you've mastered, what's fading, what's next, brought back just before you'd forget.

Welcome back — you've got the passé composé down. The thread still open was the irregular participles (né, mort, venu). Pick up there?

↺ from your learning path

You

yeah let's keep going

your tutor

Good. Quick one: how would you say “she was born in Lyon”?

You

elle est née à Lyon

your tutor

née agrees because it takes être — that's the exact one you paused on last time. ✓ marked mastered on your path

A live map of what you know.

This is what your tutor sees — what you've mastered, the step you're on now, and what comes next. It teaches forward from where you are, and brings something back only when it's about to fade.

› give me a warm-up while this builds

Yesterday you locked the past tense. Say: “we shipped it yesterday.”

› lo desplegamos ayer

Clean. Now stack it: “…but today it broke.”

› lo desplegamos ayer, pero hoy se rompió

✓ two tenses, one breath — holding.

› day 3 — where were we?

Request lifecycle, mapped. Prove it: trace a POST /jobs for me.

› gateway → auth → queue producer → worker

And where does a failed job land?

› back on the queue, with backoff ×2

✓ lifecycle — mastered on your path.

› day 3 — and let's do it half in spanish

Deal. El ciclo de la petición, mapeado. Prove it: trace a POST /jobs.

› gateway → auth → productor de cola → worker

«Productor de cola» — good. And where does a failed job land? En español…

› a la cola otra vez, con backoff ×2

✓ lifecycle — dominado.

› 5 minutes while this compiles — where were we in rome?

The Republic's last decade. Why did crossing the Rubicon mean war?

› armies were banned from italy proper

And whose senate gave that old law teeth?

› sulla's, after the civil war

✓ the law — held from last week.

› 5 minutes — rome, half in spanish?

Hecho. The Republic's last decade: ¿por qué cruzar el Rubicón fue la guerra?

› armies couldn't enter italy — los ejércitos no podían entrar

Both ways — better. Whose senate gave that old law teeth?

› el senado de sila

✓ la ley vieja — held.

tuesday · the desktop app

Your tutor

Yesterday's past tense held, so today: wishes. Espero que… wants a new mood.

espero que el build pase 🤞

Subjunctive, first try. Why pase and not pasa?

because it's a wish, not a fact?

That's the entire mood. ✓ subjunctive — opened

Monday's lifecycle held. Today, the job queue — find where retries get scheduled.

worker catches the fail, re-enqueues with backoff ×2

And the ceiling? Look again.

…there's no max?? 😅

So cap what — the count, or the delay?

the delay. six retries means nothing if they pile up

That's Friday's bug, found on Tuesday. ✓ retries & backoff — flagged

Monday's lifecycle held. Today, la cola de trabajos the job queue — find where retries get scheduled.

the worker catches the fail… los reintenta con backoff ×2

And the ceiling? Míralo otra vez.

…¿¡no hay máximo!? 😅

Friday's bug, found on Tuesday. ✓ reintentos — flagged

Yesterday: the Rubicon. Today, the man — what actually made Caesar cross?

ambition? or fear of prosecution?

Both — his immunity ended with his command. Which would a senator have said?

ambition, loudly. fear, privately

Said like a Roman. ✓ motives — mapped

Yesterday, el Rubicón. Today the man: ¿qué empujó a César a cruzar? what pushed him across?

ambition? or miedo al juicio?

Both — his immunity died with his command. Which would a senator say aloud?

la ambición, loudly. el miedo, privately

Dicho como un romano. ✓ motives — mapped

wednesday · your phone

Train-sized round. Yesterday opened espero que — now doubt: dudo que…

dudo que lleguemos a tiempo

And flip it — certainty kills the mood: seguro que…

seguro que llegamos tarde 😅

Both moods, right rails, no hesitation. ✓ triggers — steadying

Coffee-line check: why did yesterday's missing cap matter?

thundering herd after a long outage

And the fix you'd propose in review?

exponential backoff, max delay, plus jitter

Jitter — you've read postmortems. ✓ the queue — solid

Coffee-line check, half in Spanish: why did yesterday's missing cap matter?

estampida — a thundering herd, after a long outage

Estampida is exactly the word. Your fix, in review?

exponential backoff, con tope y jitter

Tope AND jitter — you've read postmortems. ✓ la cola — solid

Train round: order these — Pharsalus, the Rubicon, the Ides.

rubicon → pharsalus → ides

Now the hard one: which was reversible?

…only the rubicon, before he crossed?

That's why it's the idiom. ✓ timeline — steady

Train round: ordena — Pharsalus, el Rubicón, los Idus.

rubicón → farsalia → idus

Now the hard one: which was reversible?

only el rubicón… antes de cruzar

Por eso es el modismo. ✓ timeline — steady

thursday · in the browser

web · your tutor

Reading day, as promised. Your triggers live in here: “Espero que el equipo despliegue hoy, aunque dudo que el tráfico baje.”

hope the team deploys today… though doubt the traffic drops?

Read exactly right. Which two verbs are in the mood you built this week?

despliegue… and baje

Both. ✓ subjunctive in the wild — week one closed

The auth module, as queued — first, which middleware step already touched auth?

the gateway check, from monday's trace

So why does the worker verify the token again?

defense in depth — queues can be poisoned

Connected: lifecycle → queue → auth, one thread, four sittings. ✓ week one — on your path

El módulo de auth today, as queued. First: which middleware step already touched auth?

el check del gateway, from monday's trace

So why does the worker verify the token otra vez? again

defense in depth — las colas se envenenan

Lifecycle → cola → auth: one thread, four sittings. ✓ week one — on your path

Aftermath day. Octavian inherits — why did the NAME matter more than the money?

the legions' loyalty followed the name

So when he takes “Caesar” — what is he actually claiming?

the army, basically

The next century agrees with you. ✓ republic → empire — week one closed

Aftermath day. Octavian inherits — ¿por qué el NOMBRE valía más que el dinero? why was the name worth more than the money?

the legions' loyalty — la lealtad seguía al nombre

So when he takes «César», what is he actually claiming?

el ejército, basically

The next century agrees with you. ✓ república → imperio — week closed
