Memory
How Perch carries context across sessions and across surfaces, so it gets more useful the more you work with it.
Memory is how Perch carries what it learns about you from one session to the next, and from one surface to another. It is the reason Perch gets more useful over time instead of starting from zero every conversation.
Two kinds of memory
Perch keeps memory in two layers that work together.
Project memory
Project memory lives with the work itself. On the desktop app, you can keep notes, rules, and standing instructions alongside a folder, and Perch reads them every time it works there. This is the right place for context that belongs to a specific matter or project: the conventions for this case, the format for this client, the rules for this audit.
Project memory is yours to edit directly. It is plain files you control, so you can see exactly what Perch is being told and change it whenever you want.
Durable memory
Durable memory is account level. It holds the facts and preferences that are true about you across all of your work: your role, your writing conventions, the way you like results presented. Perch builds this up quietly as you work, and recalls the relevant pieces on each turn.
Shared across every surface
Durable memory is tied to your account, not to a single surface. What Perch learns in the web chat is available in the desktop app, and the reverse. Start a line of work in the browser, continue it on the desktop, and Perch already knows the context.
This is a deliberate advantage. Many assistants treat their chat product and their power tools as separate worlds with separate histories. Perch treats them as one account with one memory, so you never have to re-explain yourself when you switch surfaces.
Applied quietly
Memory is surfaced in the background rather than as a feature you operate. There is no memory panel to manage on every turn. When something Perch remembers is relevant, it shapes the answer; when it is not, it stays out of the way. The effect is that Perch feels like it knows you, without making you do the work of reminding it.
You stay in control
Project memory is plain files you can read and edit. Durable memory follows your account and is scoped to you. When a newer statement conflicts with an older one, Perch prefers the newer one, so correcting Perch is as simple as telling it the current truth.
