A catalog of ChatGPT & Codex plugins, sorted by people.
Two Memory & Context tools whose own descriptions overlap (shared terms: layer, memory). Here's what each project says it does and the public numbers, side by side, so you can pick one in a minute instead of reading two READMEs.

We haven't run both, so we won't crown a winner. Use the list above to rule one out, then read its README and recent commits before installing. Anything that runs commands on your machine deserves a look at the code.
