I built a study tool because my notes, flashcards, and practice questions were scattered everywhere
Hi everyone,
I’ve been working on a project called RecallHaven and wanted to share it here and get some feedback from other builders.
The idea started from a problem I kept running into while studying. My notes were in one place, flashcards somewhere else, and practice questions in another tool. Switching between them made the workflow fragmented and inefficient.
I wanted a way to bring those things together into a single workflow.
RecallHaven is a study platform where you can:
• create courses and organize notes
• write notes using Markdown with KaTeX support for math
• attach quizzes directly to notes
• practice quizzes anytime
• review everything using spaced repetition
I built it mainly for studying technical subjects like computer science or math where notes often include formulas and structured concepts.
The stack behind it is:
Rust (backend)
React + TanStack Router (frontend)
PostgreSQL
MinIO for object storage
I'm currently launching it and looking for early feedback, especially about usability, confusing parts of the workflow, or missing features.
You can try it here:
If anyone wants to test the paid features I'm sharing an early feedback code for 80% off for the first month.
Code: SIDEPROJECT80
Happy to answer any questions and would really appreciate feedback from the community.
