How we compare
Your AI already remembers something. The question is whether that memory survives a second tool, a teammate, or a fact that stops being true. Here is an honest read of the options, including where the others are better than us.
| Capability | Built-in AI memoryChatGPT, Claude | A memory libraryMem0, Zep, Letta | Enterprise searchGlean and similar | GreatArrow.aiThis is us |
|---|---|---|---|---|
| Works across your tools | One vendor only | Whatever you build | A search box, not your assistant | 17 AI clients, plus web, terminal and mobile |
| Reads your company | Your chat history | You supply the corpus | Broad connectors | 40 integrations, synced and kept current |
| Knows what is still true | No — old facts persist | Rarely, and only one does it well | Indexes what exists now | Facts retire with a date and a replacement, and stay queryable |
| Tells you when it is broken | Returns nothing, looks empty | Up to your implementation | Returns nothing, looks empty | A failed search is reported as failed, never shown as empty |
| Your agents can write to it | Implicitly, and invisibly | Yes, once you build it | No write path | 420+ tools your agents already reach |
| Team permissions | Personal to each account | You build it | Strong — this is their core strength | Enforced at the database, and fails closed |
| Effort to run it | None | An engineering project | A rollout | About a minute to connect |
Columns describe the approach, not one company’s roadmap. Drawn from public documentation as of September 2026 and not independently benchmarked by us — check anything here that would change your decision. We would rather you did.
Being straight with you
Built-in memory is free, needs no setup, and for a single person inside a single tool it is the right answer. We are worth it when the context has to outlive the tool — a second assistant, a teammate, or a vendor you might leave.
Memory libraries are good infrastructure and some are excellent on the hard parts — one models time properly, which most do not. If you want to own the stack and build the product yourself, start there. We are the finished system, not a component.
Enterprise search has years of work in permission-aware indexing across large estates, and does it better than we do. It answers questions; it has no write path an agent can use and no model of a fact ceasing to be true. Teams often run both.
Connect your own mail, drive and repositories, ask it something only your company would know, and check the citations it hands back. That is the honest evaluation, and it takes about a minute to start.
