Lattice
Language learning
Crystallize what you learn.
A premium language learning app that models everything you learn and builds your fluency one connected word at a time.
Early access for serious learners. We'll email you when your spot opens. No spam.
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.
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 conversation with your tutor. They notice the words you reach for, and the ones you stumble on.
Crystallize
Every word you meet locks into one connected map of your fluency, instead of scattering across separate tools.
Return
The right words come back at the right moment, then flow into your next conversation. The loop tightens every day.
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.
Patient and methodical. Comfortable with long silences while you think.
Direct and no-nonsense. She'll push you and give you deeper feedback.
Quick and energetic, at native pace. Like texting in your target language.
Warm and encouraging. A gentler pace for when you want one.
More tutors and languages on the way.
Available at launch
Start with one of five.
Lattice opens with five 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 make you do the work - managing decks, guessing what to study, starting over every time you switch tools. Lattice does the tedious work, so you can focus on the learning.
A structure for fluency.
