Every time you switch AI tools, you start from zero. CogniCore fixes that. It saves a structured handoff from Claude Code and Codex after every turn: the goal, current state, decisions with the reason behind each, open tasks, and exact values like IDs, versions and file paths. Any other agent, including Claude.ai, ChatGPT and Cursor, can then continue the work through an MCP connector.

It’s free, open source and local-first: no login needed, and cloud sync is opt-in. In our benchmark against claude-mem 15.7.0, it completed the same tasks using 2.4–4.1× fewer tokens, with memory ready in about 1 second.
