Excali Local

By: ISON Add-on
A local-first, offline Excalidraw app in your browser — annotate screenshots, edit and organize drawings in a private gallery, present them, and customize fonts. No account, no uploads. v1.7.0 adds gallery import from ZIP and agent-driven editing.

Features & Capabilities

Excali Local is a local-first, offline Excalidraw app that lives entirely in your browser. Capture a page or select an area and annotate it, use the complete Excalidraw editor with no internet connection, keep every drawing in a private local gallery, turn drawings into presentations, and customize fonts with your own .ttf/.woff/.woff2 files. Nothing leaves your device — no backend, no account, no uploads.

What you can do:

  • Screenshot annotation: capture a full page or select an area, then annotate in Excalidraw.
  • Offline editor: the complete Excalidraw experience, no connection required.
  • Gallery & collections: save, organize, search, export, and import drawings — all stored locally in your browser.
  • Presentation mode: turn any drawing into a slide-based presentation.
  • Custom fonts: upload your own fonts or use system fonts on a fully offline build of Excalidraw 0.18.
  • Direct .excalidraw opening: recognized files get an instant "Open with Excali Local" action.

New in v1.7.0:

  • Import your gallery from a ZIP archive, including archives edited outside the app.
  • Drive the active canvas from a CLI tool or an AI agent over a connection that stays on your local machine.

Your drawings stay private — Excali Local works fully offline with no account and no servers.

Is Excali Local Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Excali Local requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
