The gist of every page, on your terms

Built for deep reading

Everything in GistNode is designed around long-form PDFs: import, navigate, mark up, and ask AI — with a freemium credit economy that only charges when AI succeeds.

PDF library

Import from your device into a private app folder. Thumbnail grid, live title search, and flexible sort: last opened, title, date added, or page count.

  • Resume where you left off
  • Safe delete with cascade cleanup

Kindle-like reader

Native PDF rendering with adjustable font size (12–32 pt), continuous scroll, and debounced position save. Jump pages from the indicator or table of contents.

  • In-book search with next / previous
  • Offline banner when AI is unavailable
  • Figure overlays: tap to analyse with AI vision

Highlights

Six colors, inline rendering, and SQLite-backed storage with precise bounds. Tap a highlight to remove it or ask AI about that passage.

Bookmarks

Per-page bookmarks with a filled app bar icon. Open the sheet to jump to any marked page in the current document.

AI assistant

Explain, Meaning, Summarize, custom questions, follow-ups, and vision analysis for figures — powered by Firebase Cloud Functions with a 30-second timeout.

  • Markdown answers with copy & share
  • Credits deducted only after a successful response

AI history

Every interaction is saved per PDF: view full responses, jump back to the source page, or delete entries. Linked to highlights with cascade delete.

Share cards

Turn quotes into branded images: Academic, Midnight, Minimalist, or Vibrant templates. Optional social handle and gistnode.app footer — export as high-res PNG.

Credit wallet

Welcome credits on first install, daily grants when your balance is low, a 50-credit cap, and animated feedback when AI uses credits.

Streak rewards

Daily opens build streaks with milestone bonuses at days 3, 7, 14, and 30. Miss a day and the streak resets — a gentle nudge to keep reading.

Rewarded ads

Optional Google Mobile Ads: earn credits for completed videos, with daily limits, cooldowns, and preloading so the flow stays smooth.

Notifications

Local reminders for daily credits and continuing your last book — scheduled in your timezone with a late-night quiet window.

Settings

Light, dark, or sepia themes; default zoom; notification time; and a share handle for quote cards — all persisted on device.
