Review the change, not the chat.
Loom's editor is built on CodeMirror 6, with inline AI autocomplete while you type and AI edits that arrive as diffs you accept or reject hunk by hunk.
In the editor
Complete, propose, decide.
Inline autocomplete
AI completions appear inline as you type. Take one, or keep typing and it gets out of the way. The AI in the editor guide shows the full flow.
Hunk-by-hunk diffs
An AI edit never lands silently. It arrives as a diff, and every hunk is accepted or rejected on its own, so you keep exactly the parts that hold up and nothing else.
CodeMirror 6 core
A fast, modern editing foundation with language support, so the files you open are highlighted and handled properly across your project.
Around the editor
The rest of the workspace is one tab away.
Source control
A source control panel with a full git graph sits beside your files, so the history of what the fleet changed is always in view before you push.
Files and previews
A file explorer, markdown preview, and an auto-detected web preview of running dev servers keep the whole project in reach without leaving Loom.
Design first
The Design tab is a website builder that designs before it builds, so frontend work starts from a deliberate look instead of a blank file.
Questions
How the diffs behave.
What happens to a rejected hunk?
It is discarded and your file keeps your version of those lines. Every other hunk in the same edit is still yours to accept or reject independently, so one bad hunk never costs you a good one.
How does the editor fit a fleet workflow?
While the six Claude Code sessions work in their terminals, the editor is where you read and shape the result yourself. The Conductor verifies tasks before they count, and the editor and git graph give you the final say.
Is the editor part of the free app?
Yes. The editor ships inside Loom Conductor, which is free and open source under Apache-2.0 with an installer around 13 MB. You pay only your model providers, directly.
Hand it the work.
