Does Basic Memory work with ChatGPT (Codex)?
Yes. Basic Memory passed every step of our test in ChatGPT (Codex) on Oct 22, 2026: it installed, connected, its tools were visible, and an agent used it to finish a real task.
Result
Steps
- install OK
- connect OK
- tools visible OK
- agent task: recall across sessions OKstore in session 1, recall in a fresh session 2 (the token only appears in session 1's prompt)
