Timeglass Gives Claude and Codex Persistent Contextual Memory of Everything You Build
Timeglass indexes file changes and terminal actions in the background, providing coding assistants with continuous chronological context across editor restarts.
Why it matters
You can stop writing manual design documents to explain things to your AI coding agents between sessions; they now remember every iteration step automatically.
TL;DR
- 01Install Timeglass locally to capture file histories and terminal logs in the background
- 02Enable the Timeglass MCP server in your Claude Desktop or Cursor configuration
- 03Ask your agent for execution summaries to verify its recall of your design decisions
Persistent Memory for AI Editors
While MCP servers can fetch active project structures, they usually lack a historical ledger of user activities. Timeglass resolves this limitation by tracking terminal logs and filesystem mutations. By storing a semantic chronological register, it allows coding models like Claude or Codex to maintain long-term workflow context across session interruptions.
Background Synchronization
Timeglass compiles your entire coding journey in the background, mapping consecutive debugging iterations and architectural changes. This compressed history is directly injected into the prompt context, allowing the assistant to understand past refactoring decisions, uncommitted draft schemas, and architectural intent without requiring manually documented development histories.
✓ When to use
- When building complex software solutions during multi-day continuous coding sessions.
- When you need to retain uncommitted design rationale and terminal history across editor restarts.
✕ When NOT to use
- When working on single, atomic scripts that do not benefit from historical context.
- When strict enterprise policies forbid background filesystem monitoring tools.
