# digestbox

> AI-powered newsletter filter. Each user gets a unique intake alias on `news.digestbox.email`; we read every issue sent to that alias, ask Claude to score each candidate story against the user's declared interests, and forward only the ones that clear the bar.

Digestbox is a filter, not a feed reader. There's no dashboard to check and no unread counter. Users subscribe to newsletters normally — they just give the newsletter their digestbox alias instead of their real email. The alias-per-user pattern means subscription membership is private to the user.

## How it works
- MIME parse: we read Mailgun's parsed form fields into a provider-neutral InboundEmail.
- HTML cleanup: deterministic boilerplate removal (footer, unsubscribe, tracking pixels).
- Block segmentation: split into candidate items (title + snippet + url).
- Rule filter: sender allow/block + exclusion terms drop the obvious no's.
- LLM scoring: Claude (Anthropic Haiku 4.5) judges each candidate against the user's interest profile, one API call per email.
- Notification: items that clear the threshold get wrapped in a concise email sent to the user's real inbox.

## Optional
- [Sitemap](https://digestbox.email/sitemap.xml): all public URLs for crawlers
- [Health](https://digestbox.email/health): JSON ok
