# KeepPlain

> Local-first memory, rules, and session history for coding agents (Claude Code, Codex, Cursor, Pi, Antigravity). One plugin keeps agent sessions with secrets redacted on your machine, so any agent can explain why a line changed, reuse past solutions, hand off when a limit hits, and turn corrections into rules. Individual features free; team features are paid with a trial.
