Why GlissNotes

Everything a notepad should have. Nothing it shouldn't.

GlissNotes combines a quick plain-text editor, a capable rich-document mode, and native desktop ergonomics in one small app.

One workspace for everything

Plain text, Markdown, source code, and rich documents live side by side in tabs with a document sidebar, open-recent, and a quick switcher.

Editing commands you already know

Duplicate, move, join, and sort lines. Toggle comments, change case, trim whitespace, auto-close brackets, and multi-select the next match. All undoable.

Recovery you never think about

Your workspace is snapshotted locally every 15 seconds. Dirty-document indicators and unsaved-change protection guard against lost work.

Find like a power user

Match case, whole word, and regular expressions with capture groups. Replace one or all, go to line, and reach every action from the command palette.

Make it yours

Thirteen themes from Clean white to true-black Ink, four font stacks, font size, line height, interface scale, page width, and more.

Sync when you want it

Optional sign-in with Google, GitHub, Apple, or an email link keeps documents and settings in step across your Macs and PCs.

AI on your terms

Improve, summarize, explain, proofread, or run a custom instruction against any OpenAI-compatible endpoint you choose.

Q4 product proposal

We recommend shipping the editor refresh first, then the sync beta. The two can be staged independently and neither blocks the other.

Ship small, ship often.
  1. Freeze scope by Friday
  2. Cut a release candidate
  3. Notify beta testers via the changelog

Optional cloud sync

Local-first, cloud when you ask

  • Sign in with Google, GitHub, Apple, or an email link
  • One workspace per account, protected by row-level security
  • Conflict detection before a newer workspace is replaced
  • Sign out everywhere and delete cloud data from inside the app

Themes

Thirteen themes, one editor

Clean is the default. Carbon, Aurora, Midnight, Plum, Slate, Moss, Ember, and true-black Ink for dark work; Paper, Sepia, Mist, and Snow for light. Pair any with system mono, JetBrains Mono, Fira Code, or a sans-serif stack.

Optional AI tools

Bring your own model

GlissNotes talks to any OpenAI-compatible chat endpoint you configure. Improve a paragraph, summarize a page, explain a snippet, proofread a draft, or write your own instruction. Insert the result below the source or replace it in place.

  • Your API key is kept for the session only and never written to disk
  • Nothing is sent until you explicitly run an action
  • Endpoint and model are fully configurable

Also in your browser

The same editor, no install

GlissNotes runs as a web app with the same themes, local recovery, and optional sync. On Android, add it to your home screen and it installs as a standalone app that works offline.

  • Works in Chrome, Edge, Safari, and Firefox on desktop and mobile
  • Phones get a sidebar drawer and larger touch targets
  • Sign in once and your workspace follows you between desktop and browser
  • Offline-capable after the first visit
