The native Mac editor for Claude Code.

Connect Claude Code through /ide and review its edits as diffs. Underneath, a fast, free editor in the spirit of Notepad++: tabs, regex, CSV tables.

Claude Code in the Incise terminal proposing an edit, shown as a side-by-side diff with Accept and Reject

One editor for code, notes and data.

A CSV file open as source text beside a live, colour-coded table

CSVs open as a table

Columns are detected for you. Sort, filter and edit cells in place, and changes write straight back to the file.

A side-by-side diff with one added line highlighted

Diff against disk

⇧⌘D compares your unsaved edits with the saved file, side by side.

Markdown source beside its rendered preview

Live Markdown preview

⌘⌥P splits the editor, and the preview updates as you type.

Swift source with syntax highlighting, code folding and several tabs

Syntax highlighting that keeps up

A tuned Scintilla engine: tabs, folding and a file tree, with no lag on large files.

Meeting notes with misspelled words underlined in red

Spell-check as you type

In plain-text notes and Markdown. Right-click a squiggle for suggestions.

Quit mid-thought. Every tab comes back as you left it, unsaved notes included, and nothing asks you to confirm.

Incise with a terminal docked below the editor, running git

The editor your coding agent drives.

  1. Claude Code, through /ideClaude sees the file and selection you're on, and shows each edit as a diff you accept or reject.
  2. Any other agent, over MCPCodex, Cursor, Antigravity, Grok Build and VS Code connect to the same small server on your Mac.
  3. Run them in the built-in terminalA real login shell docked beside the editor, a tab per agent, and a notification when one stops to wait for you.

The built-in terminal is in the direct-download and Homebrew edition. Why not the App Store one?

New in this release

1.16.1

November 10, 2026

  • Every match highlighted: while the find bar is open, every match is highlighted in yellow, and the current one is solid yellow with dark text, so it stands out in light and dark themes.
  • Regex selects the whole match: with Regex on, Next selected only as many characters as the pattern had, not the text it matched.
  • Tabs: the tab bar is announced as a group of tabs, each with its name, whether it has unsaved changes, and whether it is the selected one.
