A provider changed the pricing behind your fallback route

Why it matters: It overlaps the margin decision in your filter.

The filter explains itself

Every signal earns its place.

Paperboy does not just summarize the stream. It ranks each item against your stated focus, links the source, and explains the match.

Hacker News AI infrastructure Example

A model provider changed the pricing behind your fallback route

Why it matters

Your filter names model margin and API changes. This item overlaps both, so it ranks above generic AI news.

Why the rest disappeared

Funding gossip and beginner tutorials match your ignore list, so they never enter the brief.

Open the Hacker News RSS feed

How it works

Three inputs. One automatic rollup.

  1. 1

    Build your firehose

    Start with Hacker News or paste the public RSS and Atom feeds you already follow.

  2. 2

    Define relevance

    Describe what you are building, watching, deciding, and tired of seeing.

  3. 3

    Let Paperboy set it up

    Paperboy validates the feeds, scans recent items, ranks the best matches, saves the filter, and emails a secure confirmation link.

  4. ✓

    Get the cut on your schedule

    After you confirm the address and start the trial, your active filter refreshes the sources and sends the strongest matches daily or weekly.

Automatic, without inbox access

Paste feeds. Paperboy does the setup.

Paperboy works from public RSS and Atom feeds. It validates each URL, reads a bounded set of recent items, removes duplicates, and ranks the result against your filter. No Gmail connection or manual concierge step is required.

Straight answers

What does automatic setup actually do?

Do I need to connect Gmail?

No. Paste public RSS or Atom feed URLs. Paperboy reads only those URLs.

Does Paperboy auto-subscribe me to newsletters?

No. Many newsletters require email confirmation or expose no public feed. Use a public newsletter archive/feed when available; email-only ingestion is not part of the live preview.

Which sources work right now?

Public RSS and Atom feeds, including Hacker News and many blogs, release feeds, and research feeds.

Is the first brief automated?

Yes. Paperboy validates the feeds, scans recent items, removes duplicates, and ranks them against your filter. Delivery starts only after email confirmation and hosted trial checkout.

Do I need to wait for someone to set it up?

No. Paperboy validates and saves the filter automatically, then asks you to confirm the email address. No operator needs to approve it.
