Overview

Built to shrink the gap between class and revision.

NodeStudy reduces the time students spend rewriting notes and building revision material by hand. It generates a study set from raw classroom content, lets you refine it, and keeps the result available for later review, sync, or sharing.

From whiteboard photos to lecture audio and PDF handouts, the app routes your source through a Gemini-backed generation pipeline and returns structured, editable learning assets — with confidence signals that point out where a manual pass is worth it.

    Send the source through the Gemini-backed generation pipeline.

  3. 03

    Review

    Inspect the generated notes, flashcards, and quiz items with confidence cues.

  4. 04

    Refine

    Edit or translate the study set until it fits how you learn best.

  5. 05

    Save & share

    Store locally, sync to Firebase, or share via Study Circle.

Runtime Behavior

Resilient by design, even before setup is complete.

Remote key feed

Gemini keys load from the hosted api_keys.json, cache locally in SharedPreferences, and refresh on a 12-hour interval.

Key precedence

The app tries GEMINI_API_KEY, then _2, _3, and _4 in order until one works.

Graceful fallback

If the remote fetch fails, NodeStudy can still fall back to a local .env file when present.

Demo services

Without a production key, the app falls back to local demo services so the UI stays fully usable during setup.

Feedback mail

The Settings feedback form uses hardcoded EmailJS values — no .env needed for support mail.

Firebase config

Initialized from committed Android assets: google-services.json and firebase_options.dart.

Setup

Up and running in five steps.

  1. 1
