Copilot memory vs StremAI

GitHub Copilot memory works within a single repository, and per GitHub documentation, stored facts that go unused are automatically deleted after 28 days. It is a useful within-repo assistant memory with admin controls. StremAI is designed as a persistent, shared layer: it is not scoped to one repository, memories remain until a user archives or erases them, and what one connected agent learns can be recalled by other connected agents — across tools, and on teams, across teammates. The two can run side by side: Copilot for in-repo assistance, StremAI as the memory layer your tools share.

Verified with Claude Code and Claude Desktop; Cursor, Codex, Windsurf, OpenClaw, and other MCP clients are supported or in active verification.

What GitHub Copilot memory is great at

Copilot memory is useful for repository-scoped facts validated against the codebase. It also sits close to Copilot coding agent, review, CLI, and GitHub admin controls.

For a team already standardized on GitHub and one repository, it can be the right built-in memory surface.

The gap, as scope

GitHub documentation says Copilot facts can only be used on the same repository. It also says stored facts or preferences that go unused are automatically deleted after 28 days.

StremAI is designed for memory that crosses repositories, tools, sessions, and teammates, with user-controlled archive and erase rather than an idle-use timer.

Using both

Use Copilot memory for in-repository Copilot assistance. Use StremAI as the shared MCP layer that Claude Code, Codex, Cursor, and other connected tools can recall from too.

The practical split is in-repo assistant memory plus cross-tool team memory.

When you don't need StremAI

Skip it if you use one AI tool, in one repository, on one machine, and its built-in memory plus a CLAUDE.md or AGENTS.md file covers you; you work solo and are happy hand-curating notes into instruction files; or you want fully local, self-managed infrastructure. Open-source MCP memory servers are a reasonable choice if you prefer running your own. StremAI earns its place when agents span multiple tools, machines, or teammates, and when you want memory that is shared, attributed, and user-controlled without operating the layer yourself.

FAQ

Does GitHub Copilot have memory?

Yes. GitHub documents Copilot memory for repository-scoped facts and preferences, with admin controls.

Why did Copilot forget something it knew?

Per GitHub documentation, stored facts or preferences that go unused are automatically deleted after 28 days.

Does Copilot memory work across repositories?

GitHub documentation says facts can only be used in operations on the same repository.

What is Copilot custom instructions vs memory?

Custom instructions are written guidance. Copilot memory stores learned facts for Copilot workflows in a repository.

Can Copilot share memory with Claude Code or Cursor?

Not through Copilot memory alone. StremAI provides a shared MCP layer that multiple connected tools can use side by side with Copilot.
