AI search

When you can’t remember the keywords, just describe what you’re looking for:

last month’s cloud invoice
the budget spreadsheet Daniel sent
flight booking confirmation from last year
did anyone ask me to meet next week?

How to use it

Type the description into the search box and click AI search next to it (otherwise it’s a regular keyword search). The results page shows:

how AI understood your description
how many messages it picked out of how many candidates
a one-line reason why each message matches

Click Use normal search instead to switch back to keyword search.

How it works

AI search needs no vector database or embeddings API — any chat model works:

Understand: the model turns your description into filters in search syntax (dates, senders, categories…) plus a few groups of synonyms, covering English, Chinese and abbreviations
Retrieve: the existing full-text index returns up to 60 candidates
Pick: the model reads subjects and AI summaries, picks the messages that really match (up to 20) and explains why

If the filters return too few messages, the search relaxes automatically — first dropping keywords, then filters — and the results page says what was relaxed.

Good to know

AI must be enabled under Models; AI search uses the default model
Each search makes two model calls, recorded as “Semantic search” in usage
The model sees candidates’ subject, sender and summary, not the full body
Results are better for mail that has been through mail analysis, because picking uses the AI summaries
It only searches mailboxes you have access to
