Directory availability depends on your client. If MemoStem is not listed, use a custom MCP connection where supported. Opening a directory does not connect your account.
View public plugin on GitHubCan I try MemoStem without creating an account?
Yes, in a compatible mixed-auth MCP client. MemoStem can temporarily keep up to 10 useful conversation cards for 90 days and give you a private link to view them. At the limit, or whenever you choose to connect, sign-up and OAuth move the same cards into private pending review.
What is shared, and when?
Your AI may suggest independently teachable knowledge from the current conversation. Nothing is sent until you ask to keep it or confirm that specific suggestion. MemoStem never imports raw transcripts or hidden conversation history. Connected-account cards stay private and pending until you review and approve them; approval does not publish them.
What is eligible to become a card?
Only independently teachable general knowledge. Personal or company decisions, product principles, pricing-plan rationale, preferences, plans, tasks, reminders, meeting outcomes, project status, and autobiographical facts are excluded.
