Lattice
Language learning
Crystallize what you learn.
A premium language learning app that makes fluency feel inevitable.
Early access for serious learners. We'll email you when your spot opens. No spam.
The plateau
Every app gets you started. Then leaves you stuck.
The problem was never you - it's how they're built. And it's fixable.
Most language apps
- Courses march you through a syllabus you'll outgrow
- Flashcards make you build your own deck
- Tutors forget you between sessions
- Immersion that means uprooting your life
- Most of what you hear is still noise
Lattice
- A tutor who actually remembers you
- Conversation pitched one step past your edge
- Every word tracked across every session
- The highest-impact word, always next
- One connected memory of you, behind it all
Built on how memory actually works - not gamified guesswork.
Immersion, engineered.
Build fluency on the structure that's already within you.
Ways to practice
Every way to learn, in one place.
Nothing slips through the cracks between activities - every mode feeds the same memory of you.
-
Converse
Free-form conversation with your tutor, always pitched at the edge of what you can already say.
-
Roleplay
Real scenarios - ordering, interviews, apartment hunting - generated fresh from the words you're ready to use.
-
Calibrate
The tutor probes what you actually know, places your level, and keeps adjusting as you grow.
-
Recall
The right words resurface at the right moment, so nothing you've learned quietly slips away.
-
Games
Word games and quick challenges, built from what you're ready to practice - so progress feels like play.
Fluency isn't memorized. It crystallizes.
Every word you meet settles into one connected structure - so what you learn holds its shape, and builds on itself.
Why Lattice
Built around how fluency actually forms.
Memory, connection, and the next right word - the three things real fluency is made of, built into one system.
Tutors who remember you
Your tutor recalls every past conversation, knows the words you've struggled with, and picks up exactly where you left off. Switch tutors and they're all on the same page about your progress.
One system, not five apps
What you say in conversation feeds your review. What you review sharpens your next conversation. Speaking, listening, reading, and recall all draw on one shared memory of you.
Always your next best word
Lattice teaches the highest-impact word for exactly where you are. Bring years of Anki history or start from zero - either way, no decks to manage and no busywork.
How it works
A loop that compounds.
Every part of Lattice feeds the next. The more you use it, the more it knows you.
Speak
Have a real spoken conversation with your tutor. You produce the language out loud, thinking and responding as you go.
Review
Right after, you go over it together. Your tutor marks the words you reached for, the ones you stumbled on, and what to fix.
Crystallize
What you practiced locks into one connected map of your fluency, instead of scattering across separate tools.
Reinforce
Those words return at the right moment, in recall and in your next conversation. The effort compounds, and the loop tightens.
Your tutors
Real personalities. One shared map of what you've learned.
Switch between them whenever you like - they all remember your progress and pass notes to each other.
Unhurried
Patient and methodical. Comfortable with long silences while you think.
Spirited
Quick and expressive. She keeps things moving at a natural, native clip.
Exacting
Direct and no-nonsense. She'll push you and give you deeper feedback.
Warm
Expressive and good-natured. He'll keep you talking, and keep it fun.
Easygoing
Relaxed and good-humored. Low-pressure practice that still gets you there.
Gentle
Warm and encouraging. A gentler pace for when you want one.
Lively
Quick and energetic, at native pace. Like texting in your target language.

Bright and motivating. He keeps the momentum going and the wins visible.
More tutors and languages on the way.
Available at launch
Start with one of eight.
Lattice opens with eight languages, each with the full tutor cast and one shared memory of your progress. More on the way.
You're not bad at languages.
The apps were.
Most apps bury you in busywork - building decks, guessing what to study, starting over every time you switch tools. Lattice clears that away, so the effort you put in goes into the language itself, not the system around it.
A structure for fluency.
Be among the first serious learners to try Lattice.
Built on the science of how memory and immersion actually work - designed by a computational linguist, not a growth team.
