Relearnify

A notes app that emails you what to review

portfolio

A notes app that emails you what to review. You write notes once, and the app nudges you later when it’s actually worth revisiting.

TL;DR

  • Rich-text notes + FSRS scheduling + daily review emails.
  • Key implementation areas: a Tiptap patch, background jobs, and a one-click “summarize” flow for long notes.

Tech Stack: Next.js tRPC PostgreSQL BullMQ Tiptap Gemini API

Try it: relearnify.vercel.app

Demo

How it works (the simple version)

  1. You write a note (Tiptap editor).
  2. FSRS schedules when you should see it again.
  3. A background queue sends you a daily email with “today’s reviews”.

Email example

Implementation details that took more effort

Tiptap patching. Tiptap’s default YouTube embed is an iframe. The extension node view was patched to render a styled link instead (lighter UI, fewer distractions).

FSRS integration. The scheduling model has state (stability, difficulty, retrievability). The real work is persisting that per note and not breaking it when notes change.

Summarization. Long notes get a “summarize” button (Gemini). It is a practical shortcut during review of dense material.

What I learned

Note-taking UX has many invisible details. Keyboard shortcuts, paste handling, list indentation, and mobile responsiveness only become visible when they break. A significant part of the effort went into these edge cases.

What’s next

Working on v2 as an offline-first app. The current version needs internet for everything. Local-first with sync would be more resilient.
