Brief
Problem
Students studying with raw notes had no fast way to turn them into structured study material. Existing tools either required manual reformatting or didn't work with your own content.
Response
SimplyNote is an AI-powered learning productivity platform that helps students and self-learners study smarter using their own content. It transforms raw notes into concise structured summaries, structured learning roadmaps, interactive quizzes with explanations. SimplyNote implements a rolling-window AI quota system to ensure fairness, performance, and transparency.
Technical Decisions
- 01
Rolling-window AI quota system: tracks usage per user over a sliding 24h window rather than a hard daily reset, fairer distribution and harder to game than a midnight cutoff.
- 02
Django REST over Next.js API routes: the quota logic, PDF parsing, and AI orchestration needed a persistent process with proper task isolation, serverless functions would hit timeout limits.
- 03
Zustand over Redux: the client state surface (auth, quota display, note draft) is small enough that a store factory pattern would have been over-engineering for 3 slices.
