A picture for every card
AI-generated illustrations on every card. Pictures stick 6× harder than words alone.
Huella — for language learners
Memorize vocabulary 6× faster.
Your brain remembers pictures, not text.
Huella gives every flashcard an AI illustration and a native-speaker voice — so the meaning lands the first time instead of the twentieth.
A tiny investment that saves you hundreds of hours of wasted learning time.

After 72 hours, how much sticks?
Plain text fades fast. Words paired with images stick — the most replicated finding in memory science.

Memorable by design
Try forgetting this tomorrow.
Our image engine is tuned specifically for memorability — vivid, character-led scenes that lock the meaning into your visual memory. Tap the card. Hear it in a native voice. Whatever you're learning, that's the picture you'll remember.
From 1¢ per image.
Quick illustrations cost 1 credit (1¢). Premium cost 5 credits (5¢) — same memorability dial, different art- direction budget.
Why Huella
Most flashcard apps treat memory like a filing problem — feed it more, hope it sticks. Huella starts from how memory actually works: with a picture, a sound, and a rhythm.
If you've used a flashcard app before
Everything your flashcard app does.
But better.
You'll never want to go back to learning without images again. Try it for a week — if you go back to plain flashcards after that, we'd genuinely love to know why.

FAQ
Frequently asked questions.
How is this different from Anki?
Same proven SM-2 spaced-repetition engine. Every card automatically gets an AI illustration and native-speaker audio so the meaning lands the first time, not the twentieth.
Will my Anki cards work?
Yes. One-click .apkg import preserves your cards, review history, and media. You can export back any time — no lock-in.
What languages are supported?
30+ for native-speaker audio: Spanish (Spain / Mexico / Argentina), French, German, Italian, Portuguese (BR + PT), Japanese, Korean, Mandarin, and more. Card content can be any language you can type.
What happens if I cancel?
Your text cards, study progress, and decks stay forever — those never go away. AI illustrations work on a viewing entitlement: you can see them clearly while you're a Pro subscriber, and for new accounts, for the first 30 days while you spend your 25 starter credits. After that, if you're not on Pro, the illustrations stay safely in your account but render blurred until you subscribe. We never delete the underlying images — re-subscribing restores visibility instantly.
Is there a free trial of Pro?
The Free tier gets 5 free Premium AI images to try the generation pipeline (or 25 Quick images, your call). Otherwise just start on Free — full app, all study features, native voices, AI card text generation, all included.
