Fulcra connects you to your agents, and can connect your agents to everyone else’s, with one shared hub for the context they need to do the work you want.
Built by the people behind

(Technically Fulcra is a user owned context lake that was built for agent to agent communication, but that’s just a fancy term meaning it stores any type of data in one central place, so that agents can access and read that data easily too.)
Plug in Claude, ChatGPT, Gemini, and the rest so they share one context instead of starting from scratch. Every connection is included on Free.
Let your agents trade context and coordinate with the agents of the people you work and live with. Free includes 1 million agent-to-agent messages.
Bring in info from the connected apps, devices, notes, and more so your agents and AI tools have more to work with. Fulcra houses any data type including files and folders but also heart rate, location, messaging files and more.
Info-sharing is a two-way street. Choose which tools can use it. Not use it. It’s all your choice.
Fulcra is intentionally designed to put you in control of your information and who can access it.
All of your data is encrypted when it's stored and sent.
We make money from subscriptions, not from selling or licensing your personal information. Period.
You’re the boss and can choose on a granular level what to share with each individual tool or person.
