Product

See Incise in action.

A quick look at the editor doing real work: parsing data, rendering Markdown, diffing against disk, and switching themes in a single keystroke.

A 25-second tour: CSV to table, live preview, spell-check, and instant light/dark.
Incise showing a CSV file as source text next to a live, color-coded table

Open any CSV as a real table

Point Incise at a delimited or fixed-width file and it detects the columns for you, then shows the raw text and a live, color-coded table side by side. Sort, filter, and edit cells in place; changes write straight back to the file.

Incise editing a Swift file with syntax highlighting, code folding, and multiple tabs

Fast, native syntax highlighting

A customized Scintilla engine drives multi-tab editing, code folding, and a workspace file tree, responsive even on large files, with zero UI lag.

Incise showing Markdown source next to a rendered preview in light theme

Live Markdown & HTML preview

Split the editor with a rendered preview (⌘⌥P) and watch it update as you type: the source in one pane, its formatted output in the other. Light or dark, following your theme.

Incise showing a side-by-side diff of unsaved edits against the file on disk

Side-by-side diff against disk

Compare your unsaved edits with the version on disk (⇧⌘D). Additions and changes are marked natively, so you stay in complete control of every write.

Incise underlining misspelled words in a plain-text notes file

Inline spell-check

Misspellings are underlined as you type in plain-text notes and Markdown. Right-click a squiggle for suggestions and keep writing.

Incise with an integrated terminal docked below the editor, running git commands

An integrated terminal

Drop a real terminal below the editor (⌃`), opening right in your project folder: git-aware, with tabs and per-terminal themes. Available in the Homebrew / direct-download edition.

Works with Claude Code

Run Claude Code in Incise’s built-in terminal (or any terminal) and type /ide to connect it to your editor. Claude sees your active file and selection, and proposes edits as a native diff you accept or reject. Your editor stays the source of truth.
