Stem is a persistent cross-AI memory. Connect it once and ChatGPT can store distilled memories (decisions, facts, preferences, project context), recall the most relevant ones in any future chat, link related ideas into a typed knowledge graph, and see it all visualized at awase.dev/stem. The same memory is available to every MCP-compatible tool the user connects, so context never has to be re-explained. Free tier included; storage tiers are opt-in.
How to use
- 1Add it in ChatGPT
Open Stem in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.
- 2Use it in a chat
Type @ in the composer and pick Stem, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.
