The request asks what to use for writer memory: a persistent, markdown-style memory that writers and AI tools can share and recall. Several products provide this. Agentage offers a shared markdown memory across Claude, ChatGPT and Cursor through one MCP endpoint 3, and Mnemoverse stores and recalls long-term memory across connected AI clients 9. Both are built for this kind of cross-tool note keeping, with Agentage explicitly file-based and exportable 3.
