Split View

Split view lets you divide a gem into side-by-side terminal panes so you can watch multiple shards at once — run a build in one pane while Claude works in another.

Splitting a Gem

Press Cmd + Shift + D to split the current gem. Crystl adds a new pane next to the active shard with a draggable divider between them.

Each pane is a full shard with its own shell process, working directory, and approval mode. You can run Claude Code in one pane and use the other for manual commands, logs, or a second Claude session.

Working with Panes

• Focus a pane — Click anywhere inside a pane to make it active
• Resize panes — Drag the divider between panes to adjust the split
• Close a pane — Close the shard inside it with Cmd + W, and the remaining pane expands to fill the gem

When to Use Split View

Watch Logs While Claude Works

Split your gem and run tail -f on a log file in one pane while Claude iterates on code in the other. You see errors as they happen without switching shards.

Compare Outputs

Run the same command with different arguments in two panes to compare results side by side.

Monitor a Dev Server

Keep your dev server visible in one pane while Claude makes changes in the other. See hot reloads as they land.

Availability

Split view is available in both Free and Guild tiers.
