Hi Product Hunt 👋
I’m Erwan, a maths teacher in France and the person behind Otoolia.
Why I built it: I kept running into the same problem, for me and for my students. Every small task needed a different website: simulating a circuit, plotting a function, compiling LaTeX, merging a PDF, reviewing flashcards. Half of those sites asked you to sign up, showed ads everywhere or put the useful part behind a paywall. So I started building the tools I needed myself, one by one, and put them all in one place.
Today Otoolia has 60+ free tools in 11 categories: physics simulators (circuits, optics, mechanics, video tracking), a graphing calculator, a LaTeX editor that compiles in your browser, PDF tools (including PDF → Word), Anki-compatible flashcards with FSRS spaced repetition, teacher tools (quizzes, seating plans, exam clock), plus everyday calculators for money, sport and music.
A few principles I stuck to:
No account, no paywall. Open the page and it works.
Your files stay in your browser. PDFs, decks and LaTeX projects aren’t uploaded to a server.
English & French, on desktop and phone.
