Lemma
An open-source AI teammate for your team that learns how you work, on your Claude Code or Codex subscription.
About Lemma
Lemma gives a team an AI teammate that you share with your people: it learns from all of you, runs work in pods with their own context and builds itself around how you work, across spaces, routines and apps. Pod-assigned runs use your local Claude Code or Codex login, so it runs on the subscription you already pay for; Lemma-managed models or your own provider keys also work.
Can you use your ChatGPT plan in Lemma?
Yes. Your Codex subscription, via your local Codex login. Lemma's own page says: "Runs on the Claude Code or Codex subscription you already pay for."
