Why Knot

Built for students, not subscriptions.

Free, for real.
Notes, flashcards, the planner and the focus timer are free for good. No account, no ads, no trial that runs out.
Works offline.
Your notes and cards live on your phone, not on our servers. Study on the bus, in the library basement or on a flight.
Your AI, your key.
Plug in your own Gemini, OpenAI or Claude key and Ask Knot costs only what you use. Most weeks, that’s pennies.
