Text Compare

Compare two or three text panes in one workspace, review chunk-level changes, and merge the output locally in your browser.

Compare and merge in one surface

Use 2-way mode for direct source-to-output editing, or switch to 3-way mode when you need a Base pane and conflict review.

Local processing 2-way and 3-way Chunk controls
Workflow and controls A quick guide before you start comparing.
1. Load or paste text

Type directly in each pane, drag a file into a pane, or use the pane-level Load action.

2. Compare the current state

In 3-way mode, Compare snapshots the current Base pane and refreshes the conflict analysis.

3. Merge in place

Use chunk arrows, then keep refining the current output pane until the remaining differences match what you want.

Shortcuts: Ctrl/Cmd + J next change, Ctrl/Cmd + K previous change.

Keep the existing text merge workspace, and stage folder comparison as an overview-first surface.

What this tool does

Text Compare helps you review text changes with CodeMirror merge panes, chunk controls, and a slim change map inside one local-first workspace.

2-way mode

Compare a source pane against an editable output pane. Both sides stay editable, and each chunk can be copied in either direction.

3-way mode

Use Left, Base, and Right panes when you need conflict detection. Compare snapshots the current Base text and highlights overlapping edits that need review.
