One memory across every tool.
Not one per tool.
Two honest ways to add AI memory today: bake it into a single tool, or store chat facts behind an API you wire up yourself. Both leave a gap — the memory does not understand your code and does not travel with you. That gap is where SecondOS lives.
Single-tool memory
Lives inside one IDE. Genuinely convenient there, and genuinely gone the moment you open a different tool. No portability, no code graph.
Memory APIs
A store for chat-derived facts you integrate yourself. Flexible, but it holds free text, not your codebase — and every tool integration is your job.
SecondOS
One structure-aware map, bound to real symbols, read by every tool over MCP. It knows your code, notices when it changes, and stays yours.
| Capability | SecondOS | Single-tool memory | Memory APIs |
|---|---|---|---|
| Read by every AI tool | ● One map, all toolsCursor, Claude Code, Copilot, Cline… over MCP | ○ One IDE onlymemory dies when you switch tools | ◐ If you wire ityou build the integration per tool |
| Understands code structure | ● Symbols + graphtree-sitter parse, call-sites, routes | ◐ Editor-localindexes the open workspace | ○ Text chunksstores facts, not a code graph |
| Memory bound to real code | ● Anchored to symbolsresolved against the latest sync | ○ Session contextno binding to specific symbols | ○ Free-text factsno link to your codebase |
| Goes stale when code changes | ● Marked stalestate-bound, ranked down in recall | ○ Silently outdatedno drift signal | ○ Never noticesfacts persist regardless |
| Per-memory trust score | ● 0..1 confidenceanchored ↑, stale ↓, reused ↑ | ○ Noneevery fact weighs the same | ○ Noneno notion of trust |
| Code-version validity | ● Valid-through windowsold-as-of-version, down-weighted not deleted | ○ None | ○ None |
| Conflict detection | ● Divergent notes flaggedreview candidates, real check with a model | ○ None | ○ Nonecontradictions just accumulate |
| Assisted distillation | ● Proposes memoriesfrom your map, you accept or reject | ○ Manual only | ○ You write factsno proposals |

| Setup effort | ● One commandbunx @secondos/cli push . | ● Built into IDE | ○ You build itSDK wiring per app + tool |
The other approaches are good at what they do. The category whitespace is that none of them give you one memory that understands your code and every tool can read. That is the only thing SecondOS is trying to be.
Stop re-explaining your codebase to every tool.
