Browse version history & diff
Now that you have versions, how do you look at them? How do you compare two? That's what this article covers.

Open the version control panel
Click the "Version Control" icon in the editor's left activity bar. The panel lists every version in this book, newest first — the latest version is at the top.
Three ways to browse
1 · Click any version → preview
Click any version:
- The editor switches to read-only preview of that version's content
- An amber banner appears at the top: "Previewing an older version" + "Restore this version" / "Exit preview"
- The file tree also reflects that version's structure (deletions / renames show up)
Exit preview brings you back to the current version without changing anything.
2 · "Compare with previous"
Each version has a "Compare" button. It opens a diff view:
- Left: the previous version
- Right: this version
- Red = removed, green = added, yellow = modified
This is what the new "compare versions" step in onboarding teaches.
3 · "Compare with current"
The one you'll use most: diff any older version against what you have right now.
- "What did the AI change?" — old vs. current
- "How different is the draft from last week?"
- "What's actually changed since 'revision pass 1'?"
Filters
Top of the panel, three filters:
| Filter | What |
|---|---|
| Hide auto snapshots | Show only named (manual) versions |
| By file | Only versions that touched a specific file |
| By time range | Jump to last month / week / today |
Cross-file versions
Slima's versions are book-scoped — one version captures the state of every file at that moment. So:
- "Revision pass 1" includes the whole book as it was
- Not just one chapter
- Restore is whole-book (or per-file, see Restore the whole book or a single file)
Find specific text
Want to know which version added a particular sentence?
- Select it in the editor
- Right-click → "Find this passage's history"
- Slima jumps to the version where it first appears
