Paste up to twenty links at once and smry works out what each one is — a feed, a site, an X account, a creator, a topic, or a page that publishes nothing at all.

​
Paste the pile

You do not have to know which of your links publish a feed. Hand over the whole list and smry resolves each one on its own.
follow all of these and put them in a collection called Signal: stratechery.com, x.com/paulg, tiktok.com/@zachking, https://simonwillison.net/atom/everything/
follow_feeds · 1 call Each link gets its own outcome. One dead URL never throws away the nineteen that worked, so a partial result is the normal, legible answer rather than an error. The first six rows go through one call. A topic is its own call, and so is a page with no feed. All eight end up as the same kind of followed source. An @handle on its own is too short to send. Use the profile URL, or the x://handle short form. That last row is a monitor. It matters here because a monitor’s detected changes arrive as feed entries, so it reads like everything else.

​
Follow a creator, not a platform

An X account, a TikTok handle, an Instagram profile, a Threads account — paste the profile link and it becomes a source. No feed URL to hunt for, no scraping to set up on your side.
follow x.com/paulg and https://www.threads.com/@zuck
Because the machinery underneath is identical, one Collection can hold a newsletter, a creator, a news query, and a pricing page that changes twice a year. Your agent asks that Collection one question and gets all four back in one stream.

​
Follow a topic

Some things you want are not published by anyone in particular. Give smry the topic instead and it becomes a durable source you can follow, filter, and poll like a feed.
follow “open source databases” as a news feed in my Research collection

​
Filter a Collection in plain English

A Collection can carry a written rule about what belongs in it. No keyword syntax, no boolean operators — say what you want.

smry classifies a recent sample first and shows you what it would have kept and what it would have dropped, with its reasoning. You look, then you apply it. A preview stays valid for fifteen minutes, so the thing you approve is the exact thing that gets saved.

​
A feed that posts forty times a day

One noisy publisher can bury nine good ones. Two things help, and they stack. A Collection filter drops the categories you never read. Per-entry feedback handles the rest: tell smry “less like this” on an entry and it hides that one without quietly rewriting your filter behind your back.
less like this — I don’t want their sponsored roundups

​
Catch up without reading twice

The point of following things is the second visit, not the first.
what’s new since yesterday?
From there it is the rest of smry: read the two entries worth reading, save the one worth keeping, and ask your library about it next month. For a scheduled agent — one that wakes up, works, and exits — smry holds the read position on its own. Your agent stores no cursor, no timestamp, no list of what it already saw. It asks what changed, processes it, and says it is done. Nothing else in the reading space works this way.

​
Questions

Then a monitor covers it: smry checks the page on a schedule and turns each change into an entry. See Watch a page for changes.
A free account follows 100 sources across 5 collections. Paid plans go to 1,000 sources across 100 collections, and 25,000 across 1,000.
Yes, and it is the point. A newsletter, an X account, a TikTok creator, a news query, and a monitored pricing page sit in one Collection and come back in one stream.
Yes. Ask smry for feeds on a topic, or ask what a single site publishes. Discovery does not subscribe to anything — you follow what you pick.
Ask your agent to unfollow it. Destructive feed changes preview what they would affect before they happen, so an over-broad instruction shows you the damage instead of doing it.
