Archive Insights AI Digest (opt-in AI cleanup suggestions for the senders you archive)

What it is

SuperMail already tracks your Archive Insights — which senders and domains you archive, whether you opened them first, and how long you looked. The AI Digest turns that into concrete cleanup suggestions: an AI reviews the senders you archive (especially the ones you never open) and recommends what to do about each — set up a filter, unsubscribe, or mute — and every suggestion has a one-click Create filter button that opens the filter editor pre-filled.

It reaches you two ways:

• On demand — in SuperMail → Archive Insights there's an AI Digest section with an "Analyze with AI" button. Click it to get suggestions right now, plus a one-line summary of your archiving pattern (how much you archive without opening, and how long you spend reading first).
• Automatic (opt-in cadence) — a digest inbox card posted on a schedule (Daily / Weekly), so you get cleanup suggestions even when SuperMail is closed. The card's button takes you to SuperMail to act on them.

It is OFF by default and in development (behind the Lab / dev gate) until it ships.

Where to find it

Turning it on

Settings → Email & Summaries → Archive Insights AI digest — a toggle plus a cadence picker (Off / Daily / Weekly). The row only appears once the feature is revealed (shipped, or via the Settings → Lab toggle / AMC_SHOW_SUPERMAIL_ARCHIVE_DIGEST=1).

How it behaves

Privacy — what leaves your device

To make specific suggestions (e.g. "filter Geek Square"), the sender and subject of the emails you archive are sent to the AI provider. That is stated on the toggle. If you do not opt in, nothing is sent. Everything else stays on your machine: the analysis snapshot used by the automatic digest is encrypted at rest, and the record of what has already been suggested is stored hashed (no readable email address on disk).

Limits / planned follow-ups

• Week-over-week trends (how your archiving changed vs last week) are a planned follow-up — today the digest shows your current-period pattern plus the recommendations.
• The automatic card's button opens Settings → Email & Summaries (where "Open Supermail" reaches Archive Insights); a direct jump to the Archive Insights view is a follow-up.

Contract: supermail-archive-digest-contract.

For agents

How it works (under the hood)

• The SuperMail screen computes a bounded shortlist of "candidates" — the senders/domains you archive, minus any you've already filtered — from your local Archive Insights data. It never digs into files on disk.
• It sends that shortlist to the main app, which runs one cheap AI call with a per-account daily spend cap, validates the result, and returns the recommendations. The AI key never touches the SuperMail screen, and the AI can only ever recommend a sender that was actually sent to it — a safeguard so a crafted email subject can't hijack the analysis.
• It never repeats itself. The on-demand button and the automatic card share ONE memory (in the main app) of what has already been suggested, and both skip senders you've already filtered — so you never see the same recommendation twice.
• The automatic card runs off the last snapshot your app synced while SuperMail was open; if you haven't opened SuperMail in a while, it is skipped rather than run on stale data.

Desktop-only (the analysis + snapshot never leave the device except the single AI call).
