Cross-AI Memory Bus

Continue the same research session across Grok, ChatGPT and Claude

Problem

After a user hit Grok's free limit, they wanted to move the research to ChatGPT or Claude but could only copy a huge block of context by hand, and the answer still hallucinated afterward. Developers also cycle through Claude Code, Codex, Cursor and Copilot, where each session's memory is siloed and background must be re-explained every time.

Solution

A local-first memory layer: a browser extension or MCP server captures key conclusions from each platform's sessions into structured markdown memory files, then injects relevant memory into a new chat on any platform with one click. Users can view, edit and delete each memory so mistakes don't propagate.

Users

Researchers, developers, content creators and consultants who use several AI tools heavily

MVP

Browser extension to export a session summary in one click; local markdown memory store with tags and search; one-click inject selected memory into another platform's input box; MCP read support for Claude Desktop; each memory tagged with source platform and timestamp

Revenue

Free base tier plus subscription for multi-device sync, shared team memory and better auto-summarization; optional one-time desktop license

Why now

People already juggle three or four AI platforms with separate free limits, so switching is routine; MCP and browser extensions lower the bar enough for an indie dev to ship in weeks
