Hey Product Hunt! 👋 I'm Tomo, the developer of Lecta.

I wanted to turn boring exam prep into games I could play with friends. I also wanted one home for my study material, where a handout could become more than just another file to read.

Today, I'm launching Lecta: turn your own study material into games with friends.

Add a PDF, a handout photo, or a lecture recording. You can use that same material for a race with friends, then come back to it for your solo study session.

Here are a few things you can do:

🏎️ Race your friends on your exam topics: In Formula Race, correct answers make your car faster. Play solo or invite friends to race on questions from your material.

🎮 Make it a quiz night: Play Quiz Rush or Jeoparty with friends, or try Hyperlane's space race. The questions come from what you're studying.

📝 Study at your own pace: Turn the same material into notes, quizzes, and flashcards when you want a quieter session.

💬 Ask about the part you don't get: Use the AI tutor to work through the bits you're stuck on.

🔁 Come back to what you missed: Read the explanations and save questions to review later.

I wanted the games and the quieter study tools in the same place. Sometimes you want to race a friend. Sometimes you just need to understand one question.

Bring one handout. Start with a race.

Lecta is available on iPhone in English and Japanese. There's a free plan with daily limits, and Premium if you need more. Web is coming soon.

I'd love to hear what works for you and what feels off, especially in the games. Feel free to ask questions here, too.

Fun question: What subject would you turn into a race, and who would you challenge first?
