Version Control keeps a complete history of every memo inside 📝Version History — every edit is retained for 13 months, browsable on a timeline with rendered and markup diffs, and restorable to any point with one click. It exists so an edit is never truly final — mistakes, deletions, and drift are all recoverable. It's for owners who want the safety net of full history without managing it themselves.
Key Capabilities
- Automatic retention — every edit lands in a version log, retained for 13 months, no setup required
- Timeline scrubber — step through revisions on a timeline above the memo; arrow keys move between revisions, Home and End jump to the ends, and older revisions load as you reach the start
- Rendered diff — see a revision as it reads in the memo, with added text in green and removed text in red, in the same centered column as the memo
- Markup diff — compare the markdown source of the title, body and Notes, with additions in green and removals in red
- Compare and filters — compare a revision against the one before it or against the current memo, and narrow the timeline by collaborator or date
- Daily memo history — daily memos keep their history too; open a day's history from the journal to read and compare its revisions
- One-click restore — restore a memo to any prior version as a full snapshot
- Owner and collaborators — the memo's owner and its invited collaborators can open its history; only the owner can restore a version, and Notes stay hidden from anyone without Notes access
Getting Started
- Open a memo and find its History panel in the editor sidebar
- Move along the timeline, or use the arrow keys, to pick a revision
- Read it in Rendered to see what changed as it reads in the memo, or switch to Markup for the source
- Click Restore this version, then confirm. Restore brings back the title, body, and notes together; if the memo changed while you were looking at history, or people are editing it live, the restore is refused so nothing is overwritten and you can reopen history and try again.
- For a daily memo, open History from that day in your journal. Daily history is read-only.
FAQ
- How far back does history go? 13 months of retained versions.
- Can collaborators see version history? Yes — invited collaborators can browse and compare versions, but only the owner can restore one.
- Does restoring delete newer versions? No — restoring creates a new version snapshot from the old content; nothing in the log is deleted.
- Can I restore a daily memo? Not yet — daily memo history is read-only.
- Can an AI agent read my history? Yes — agents connected through the MythOS MCP can list and read a memo's versions, daily memos included, and can restore a memo version on your behalf. Daily memos can't be restored.
