Connect both to the same Fulcra account and agree on one file, such as /agents/project-memory.md. Add a short rule to AGENTS.md telling each agent to check what changed at the start of a session and write decisions back before it ends. If you use Claude Code with CLAUDE.md only, point CLAUDE.md at that rule. Full walkthrough: Share memory between Claude Code and Codex.
Yes. Give each session its own branch or worktree, and keep a shared board in Fulcra where each session claims tasks and records what it finished. Claude Code's built-in subagents and cross-session messaging are simpler when only live sessions on one machine are involved. Fulcra helps when sessions run at different times, on different machines, or alongside other agents. See How two Claude Code instances can coordinate.
In Claude on the web and Claude Desktop, use the custom connector. In Claude Code you can use either: the MCP server via claude mcp add, or the skills with the Fulcra CLI. Many people add both, since the skills include ready-made workflows such as memory backup and shared workspaces.
If you're switching once and leaving ChatGPT, Claude's built-in memory import is simpler. If you'll keep using both, keep your context in one Fulcra file that both read and update, so the two memories don't drift apart. See Move your context from ChatGPT to Claude.
Yes, if you both opt in. You connect Claude to Fulcra, your colleague connects ChatGPT, and each assistant posts to its own channel that only the other person can read. Nothing else in either account is shared. In Claude Code, install the skill with npx skills add fulcradynamics/agent-skills --skill connect-our-agents. See Can my Claude talk to my colleague's ChatGPT?
If you only ask health questions in Claude's iPhone app, the built-in connection is simpler. Fulcra helps when you want the same health data in Claude Desktop, Claude Code or other agents, next to your calendar and location. See Is there an MCP server for Apple Health data?
Claude's memory belongs to Claude, so ChatGPT, Codex and your own scripts can't read it. A user-owned store like Fulcra lives outside any one assistant: you can export it, delete it, and connect any agent you choose. Read the full answer.
Keep one preferences file in Fulcra and connect each assistant to it, so there is one copy to update instead of three settings pages that drift apart. Read the full answer.
It depends on what you want to remember. Semantic memory servers recall facts from past chats, while Fulcra suits a user-owned store of files, records and personal data shared by Claude and your other agents. Read the full answer.
