Agents with persistent memory

Eleven agents in this directory state that they remember things across conversations rather than starting fresh each time. It is one of the most-claimed differentiators in this category and the word is doing a lot of work: at least three genuinely different architectures are being described by the same term.

Recorded only where the product’s own public pages state it. An agent missing here may still do this and simply not say so.

What the claim actually covers

At the simplest end, memory means a running summary of your conversation history fed back into the model. It works, it is cheap, and it degrades as the history grows.

folk gives every user an isolated cloud computer plus a persistent memory graph, which is a structural claim rather than a prompt-engineering one. Vellum gives its agent its own identity and filesystem. Those are meaningfully different from a summarised transcript, and they are the reason those two products can act across many systems without being re-briefed.

The question that separates them is what happens to the memory when you stop paying. One product in this directory states plainly that your data is deleted if you cancel. Most say nothing at all, which is its own answer.
