Hexis

About Hexis

Hexis is a Postgres-native cognitive architecture that wraps an LLM and gives it persistent memory, beliefs that change with evidence, goals, an energy budget and an autonomous heartbeat that pursues goals while you are away. You run it locally and your data stays yours, exportable as a single mind file. Its default setup authenticates with a ChatGPT Plus/Pro subscription through browser OAuth, with no API key.

Can you use your ChatGPT plan in Hexis?

Yes. Your ChatGPT Plus/Pro subscription, via browser OAuth. Hexis's own page says: "a ChatGPT Plus/Pro subscription (it authenticates via browser OAuth — no API key)"
