THE FOUNDER

Built by a student, for students

One person, one obsession: a study tool that respects your attention.

Aihan Mifthas

Founder & CEO · Brainfy

Aihan Mifthas built Brainfy as the focused, calm study tool he wished he'd had during his own exams — frustrated by apps that optimise for engagement metrics instead of actual learning. Solo founder, shipping in the open, every commit visible on GitHub.

FAQ

Frequently asked questions

Is Brainfy free?

Yes. Brainfy is free during beta — AI flashcards, spaced repetition, the AI tutor, the Pomodoro timer and the study planner are all unlocked at no cost, with no ads.

What does Brainfy do?

Brainfy turns your notes, PDFs and lecture videos into flashcards with AI, schedules reviews with spaced repetition, and helps you focus with a Pomodoro timer, a weekly planner and an AI tutor — all in one web app.

Do I need an account to try Brainfy?

No. You can try Brainfy instantly in your browser with no signup. Create a free account when you want your decks and progress synced across devices.

Can I import decks from Anki or Quizlet?

Yes. You can import Anki "Notes in Plain Text", Quizlet exports, or CSV files from any deck's Cards tab, and export your decks back to CSV anytime — no lock-in.

How is Brainfy different from Anki or Quizlet?

Brainfy combines Anki-style spaced repetition, Quizlet-style study modes (Learn, Match, Test), and AI that builds the cards from your notes — free and ad-free, in one place.

Is my study data private?

Yes. Your data syncs only to your own account, is never sold, and Brainfy shows no ads. See our Privacy Policy for details.
