Firmament vs built-in agent memory

Built-in memory helps one person's agent remember across their own sessions. Use Firmament when a whole team's agents need to share what they learn, owned by you and portable across every tool.

Keep your agent's built-in memory. Firmament is the layer it doesn't have: shared across people and tools, governed by human approval, and owned by your team as an asset instead of a personal profile a vendor keeps.

Free for a team of three. 30-day trial of everything.

Doesn't my agent already remember?

For you, yes. Claude, ChatGPT, and Cursor can recall your own past chats. But that memory is personal, it lives with one vendor, and your teammate's agent never sees it. Firmament is the shared layer: what one agent learns, every agent on the team knows.

Can't I just move my memory between tools?

Only by hand. Some tools now let you export your own memory profile, but moving it from Claude to ChatGPT to Cursor is manual reconstruction, and it stays personal to you. Firmament holds your team's knowledge once and serves it to any agent that speaks MCP, across every tool, with no migration.

Who actually owns the built-in memory?

Not your team, really. It's a personal profile the vendor keeps, a picture of how one tool sees one person. Firmament is a shared asset your company owns and governs: full export, version history, and human control over what it contains.

What does "a team brain" actually mean?

One agent learns something, a human approves it, and every agent on the team has it, across every tool. Built-in memory keeps each person's agent on its own island. Firmament connects them, so the lesson your teammate's agent learned this morning guides yours this afternoon.

In fairness

When built-in memory is enough

If you are one person who never needs to share what your agent remembers or move it between tools, built-in memory is convenient and free. Firmament earns its place the moment a teammate should benefit from what your agent learned, or you want to own and govern it as a team.
