DexLabs Note App — Docs

What this is

DexLabs Note App is a fast, keyboard-and-touch-friendly text editor and file manager that runs entirely in your browser. There's no server backend beyond optional Google Drive sync — your notes live in this browser's local storage, organized into folders, and sync to your own Drive account if you sign in.

Getting started

From the homepage, tap Note App to open the file manager. If this is your first visit, tap the + button to create your first file or folder. Tapping a file opens it in the editor.

The file manager

The file manager (/filemanager) is the app's entry point. Every note lives in a folder tree you can search, sort, and reorganize.

Its left sidebar holds app-level tools: Settings, Debug, Sync to Cloud, and Asteroid Belt.

Tap Select to enter select mode: pick multiple files and Move, Copy, Download, Delete, or Batch apply a function to all of them at once — "zap mode."

Three modes, one note

Every open note has a URL shape of /note/:id/:mode.

  • Base — the plain text/code editor.
  • Diffusion — a side-by-side Raw/Morph comparison.
  • Mermaid — a Mermaid.js diagram editor with live preview.

Selecting and editing text

Long-press to select a word on any text surface. A small menu appears near the selection with the actions appropriate to the current view.

Sidebar functions

Open a note and tap the second sidebar icon for the full function catalog — formatting, find/replace, cleanup, ciphers, hashing, HTML tools, and more.

Chains

A "chain" is a saved sequence of find/replace steps and certain functions that can be re-run on any note or across many notes.

Asteroid Belt

Link two notes by writing {{note title}} in either one. Open Asteroid Belt from the file manager sidebar to see notes as a force-directed graph.

Settings

Light/dark theme, editor syntax theme, line numbers, word wrap, and the two exclusive modes all live in Settings.

Staying in sync

Sign in with Google from the homepage to back up notes to your Drive app-data folder. Everything still works fully offline without an account.
