Your two AIs don't know about each other. Give them one notebook.
Put both assistants on the same lane in a shared notebook and they read each other's notes. Each AI has its own memory, if it has one at all, and they don't talk to each other. People end up re-explaining a project to the second assistant, or copying answers between tabs. The fix is a shared record both can reach: one place where either AI reads what the other did and leaves a note of its own.
In Memoshelf a lane is a named strand of the notebook. Two assistants on the same lane see the same notes and the same pinned rules; a bot on another lane does not. You choose the lane name when you connect each AI (for example "research"), and you can change it later on the account page.
How it runs, in one example:
- Connect Claude and ChatGPT to Memoshelf, both on lane "research".
- In Claude: "Read what happened last on research, then summarize the three papers I pasted." Claude reads the lane, does the work, and stores a note: "Summarized papers A, B, C; open question on C's sample size."
- In ChatGPT, a new chat: "Read what happened last on research and draft the email to the author of paper C." ChatGPT reads Claude's note and starts from it. No pasting.
- Both keep following the same "How we work" page, so the names, formats and rules stay consistent across assistants.
Limits worth knowing: notes are plain text you can read on the account page; nothing is sent between the assistants directly, only through the notebook. Keep passwords and private details out of it.
