KeepPlain
KeepPlain saves and searches coding-agent sessions so developers can trace code changes, reuse past solutions, and hand tasks between agents. Teams can also share reviewed rules and link sessions to pull requests.
Who it's for
- Developers using Claude Code, Codex, Cursor, Pi, or Antigravity who need to find context from earlier agent sessions.
- Teams that want reviewed coding rules and shared memory to reach their agents.
- Pull-request reviewers who want links from commits to the sessions that produced them.
How it fits your workflow
Install the plugin and enable it for use with a supported coding agent. KeepPlain stores session history and removes secrets on the user's machine before anything leaves it.
Search previous sessions to see why code changed or find a solution. Agents can also check session examples through MCP, and developers can turn useful sessions into rules, skills, or prompts.
For teams, reviewed rules and shared session memory reach agents. Pull requests can show the sessions associated with their commits, and Insights reports on agent time, merges, and cost.

Key features
- Explain code changes
- Point to a line of code and view the agent session associated with the change, including the relevant conversation context.
- Memory across agents
- Search past sessions for earlier solutions and let an agent pick up work across the supported coding agents.
- Handoff at an agent limit
- Build a brief on the user's machine so work can continue in Codex or Pi when Claude is near its stated usage limit.
- Rules from corrections
- Turn corrections made across conversations into rules that are read by the agents the user works with.
- Session summaries
- Condense longer sessions into the moments that mattered, alongside the code from each turn.
