Timeline

Not auto-save. Time travel.

THE PROBLEM

Ctrl+Z only goes so far.

You're deep in a coding session. An AI tool makes changes across 5 files. Something breaks. Ctrl+Z doesn't help — the changes are spread everywhere.

Or worse: your IDE crashes. You reopen it. Where were you? What did you lose? Auto-save might have saved something, but which version? The broken one?

Git doesn't help here. You commit after features work, not after every keystroke. The gap between commits is where work disappears.

THE SOLUTION

Every moment, preserved.

Timeline buffers every keystroke. Every save creates a snapshot. Every AI session is grouped together. Go back to any moment — not just commits, any moment.

Keystroke Buffering

Everything you type is buffered locally. Crash? Power outage? No problem. When you reopen, you're exactly where you were.

AI Session Grouping

Claude Code made 20 changes across 5 files? Undo the entire AI session with one click. All the changes, rolled back together.

Visual Comparison

See exactly what changed between any two points. Diff view shows additions, deletions, and modifications clearly.

Intent Tracking

Timeline knows why you made changes, not just what changed. "Refactoring auth" vs "fixing bug" — context preserved with history.

"Explore different approaches risk-free. Experiment boldly. Timeline has your back."

TECHNICAL DETAILS

How it works.

Local Storage

All timeline data is stored locally on your machine. Nothing is uploaded unless you explicitly opt into cloud sync. Your history is your history.

Efficient Compression

Timeline uses incremental snapshots and delta compression. Storing weeks of history typically uses less than 100MB, even for large projects.

Retention Policy

Recent history (last 7 days) is kept at full resolution. Older history is compacted to save space while preserving key milestones like saves and AI sessions.
