Memory

Persistent, searchable, editable memory across sessions.

Memory is what makes Hermes feel like an autonomous workspace instead of a chat session. Every observation, every important plan step, every fact the user pins gets written to the local Dexie store and recalled on demand.

Memory kinds

Kind	Lifetime	Example
`conversation`	session	"User clarified that the goal is daily PnL only"
`project`	project	"This project tracks Hyperliquid USDC delta-neutral"
`preference`	global	"User prefers TL;DR before details"
`tool`	global	"wallet.read_balance returns wei not eth"
`knowledge`	global	Indexed document chunks

Recall

Recall is hybrid: BM25 over tokens by default, with vector recall when an /embeddings endpoint is available on the configured model provider.

const recalled = await memory.recall({
  query: "wallet balance for current address",
  kinds: ["project", "tool"],
  k: 6,
});

Editing

The Memory page lets you browse, edit and forget entries. Forgetting is hard-delete from IndexedDB; there is no soft-delete table and no shadow copy.
