The algorithm

An algorithm that worksfor you, not your feed.

Feeds are built to keep you scrolling. Summate is built so you can stop. Every morning it reads everything you follow, keeps what matters to you, and learns what you like.

Two kinds of algorithm

Your feed wants your time.Summate gives it back.

A feed's algorithmSummate's algorithm
  • A feed's algorithm: Wants as much of your time as it can get. Summate's algorithm: Saves as much of your time as it can.
  • A feed's algorithm: Shows what gets clicks. Summate's algorithm: Shows what matters to you.
  • A feed's algorithm: Never ends. Summate's algorithm: Ends when you're caught up.
  • A feed's algorithm: Decides in secret. Summate's algorithm: Shows what it skipped, and why.

An example morning: 8:12 and still scrolling in a feed, or 7:11 and caught up with a brief.

Every morning

What happens before your brief arrives.

Eight things, in order, for every piece your sources published since the last brief.

  1. 1 of 8

    It clears out the noise

    Newsletters are full of things that aren't news: ads, sales, receipts, sign-up emails and posts that only sell something. Summate spots them and takes them out before your brief is written, so they never cost you a minute, or a credit.

    It follows your rules

    Tell it what you don't want, the way you'd tell a friend: “No sports.” “Skip crypto prices.” Every piece is checked against every rule, and you can see what each rule caught.

    Your rules

    • “No sports”caught 36 this week
    • “Skip crypto prices”caught 13 this week
    • “Nothing about celebrity gossip”caught 4 this week
    • Add a rule, like “no product launches”

    It knows your topics

    Name the topics you care about, or let Summate suggest them from your sources. Each story lands under the right one. Something off topic only gets in when it's big news, marked “Other notable”.

    One story, not five copies

    When several of your sources cover the same news, you get it once, from the best version, with a note of who else covered it. A story many of them cover moves up, because it probably matters.

    Biggest first, short every day

    Stories are ranked by how important they are and how well they fit you. A busy Tuesday and a quiet Sunday both come out as a short read, and no single source can take over.

    Busy Tuesday

    No single source gets more than a quarter of your brief.

    It checks every takeaway

    Each takeaway is checked against the words it came from. If the source doesn't back it up, it's dropped. In the reader, tap any takeaway to see the exact passage.

    Write the no-list first, and share it before the pitches.

    Checked against the source

    “The teams that ship the most write down what they won't build this quarter, and they share that list before anyone pitches.”

    It learns what you like

    Summate notices what you open, read to the end, star and highlight, and gives more room to the sources and topics you love. It learns only from your own reading, and it never hides a topic you asked for.

    What it learned

    Week 1 → week 6
    • NNot BoringYou read every issue
    • SSimon Willison's WeblogYou highlight his posts
    • LLenny's PodcastYou finish the episodes
    • TThe VergeYou skip most of it

    Your topics and rules always come first. Learning only changes the order.

    It shows its work

    At the bottom of every brief: how much it read, what it merged, and what it skipped and why. One tap shows everything it left out, so nothing disappears quietly.

    At the bottom of today's brief

    Read 214 pieces from 32 sources. Kept 18, merged 9.

    Skipped 187

    • 45 off your topics
    • 52 ads and promotions

Questions

Good questions, short answers.

Want to see where your brief opens? Read about the reader.

Will I miss something important?

Big stories get in even when they're outside your topics, marked “Other notable”. And the bottom of every brief lists everything that was skipped, with the reason, so you can check.

How does it learn what I like?

From what you do with your brief: what you open, how far you read, what you star and what you highlight. It starts neutral and settles over a few weeks of reading. Your topics and rules always come first.

Is my reading used for anything else?

What you read tunes your own brief, and it's never used to rank anyone else's.

Do skipped pieces use my credits?

No. Ads, receipts and anything skipped are taken out before summaries are written, so credits are only spent on what makes your brief.

Can I change how it decides?

Any time. Add or edit topics, write or remove rules, group your brief by topic or by source, and leave notes like “explain the jargon”.

What does it do with videos?

The same: it watches the whole episode, keeps the moments worth your time with their timestamps, and puts long videos in a watch guide with a line on why each is worth it.
