The note app built on the Feynman Technique
Write your notes in Ankra or let AI draft them from photos, PDFs, and recordings. Then turn them into flashcards, quizzes, and Feynman sessions that reveal what you actually understand.
Join thousands of students using Ankra to make active recall a daily habit.
How Ankra works
You sat through the lecture. You took the notes. That is where most apps stop, and where Ankra starts. Everything you capture becomes something that teaches you back.
Type them in class, or let AI draft them from a photo, a PDF or Word file, a Google Doc, a YouTube video, or a lecture recording. Rich text, real math, images, and links between notes.
Any note becomes flashcards and quizzes in a tap. Spaced repetition brings each card back right before you would forget it.
Explain the topic back in your own words. Ankra grades what you got right, what you got wrong, and what you missed.
Your notes live here
Take notes the way you already do: headings, highlights, tables, images, and real math equations. Write them yourself or let AI draft them from photos, PDFs, audio, even video. Every note stays yours to edit.
Reference one note inside another instead of copying the same explanation into five documents. Researchers call it the Zettelkasten method. You can call it never losing anything.
Generate a note from a lecture recording, a textbook photo, a PDF or Word file, a Google Docs or Slides link, or a YouTube video, then edit it like anything you wrote yourself. AI gives you a head start, not a locked document.
Notes open and save with no connection, then sync across iPhone, iPad, Mac, and Android when you are back online.
No account needed. It runs right here in your browser.
You talk. Ankra listens and takes notes.
The moment of truth
Rereading feels like learning. Explaining is learning. Start a Feynman session from any note or topic, explain it in your own words, and Ankra grades what you got right, what you got wrong, and what you missed. Every gap becomes a flashcard.
Exam Planner
Add an exam and attach the decks it covers. Ankra paces the remaining cards day by day, keeps a revision buffer before the date, and rescues reviews that would have come up too late.
Why not just use a doc?
Forty pages of notes in Google Docs look like progress. But a doc cannot tell you what you actually know. Keep your notes where every page can quiz you back.
Who it is for
Turn a semester of lecture notes into decks before finals, diagrams and all.
Write real equations in your notes, then drill them as flashcards.
Link people, dates, and events across notes, then quiz until the timeline sticks.
Collect vocabulary in class and let spaced repetition handle the memorizing.
Tame huge volumes of material with linked notes and daily reviews.
If you can take notes on it, Ankra can quiz you on it.
Better Together
Study together, your way. Share a single deck in a tap when you just need one set of cards, or start a Study Circle, a shared space where your whole group builds and keeps many decks together. Everyone contributes cards on their strongest topics and checks each other's work, so you end up with decks that are thorough, accurate, and built by people who actually know the material.
