Memory Sync
MemoryBase is a cross-platform memory layer for people who use multiple AI tools daily. It syncs your conversations across ChatGPT, Claude, Claude Code, Cursor, and Gemini, so whatever you tell one AI is available to all the others.
Conversations get captured automatically as they happen, organized into projects and topics, and the relevant pieces surface in whichever tool you open next. You stay in control of what gets stored and what loads where.
Available as a Chrome extension and web app at memorybase.app. Free and Pro plans, with more integrations on the roadmap including OpenClaw, Slack, and Google Docs.
