Know the moment it changes.
A competitor's pricing page. A regulator's guidance. A topic you can't afford to miss. Radar watches the sources you name and the subjects you describe, tells your AI what moved, and never tells you the same thing twice. In beta — it works, and it will change.
$15 a month, and it isn't just this app — every Parsons product is on the same subscription. Cancel any time. Findings are deduped before they count, and a watch never checks a source more often than you said.

Name a source. Describe a topic. Read what moved.
Watch a page.
A URL and a cadence. Daily, hourly, weekly. It keeps the last version and tells you the diff, in words, when it changes.
Watch acme.com/pricing daily.Paste one link into your AI.
Your account comes with one private address. Paste it into Claude, ChatGPT or Cursor once, and Radar's tools are there. No AI of your own? The console has chat built in.

Not a page — a subject. "Anthropic model releases." "California solar incentives." It reads the sources it finds and files what's new, once.
Watch for changes to California's solar incentive rules.Ask what moved.
"Anything on pricing this week?" It reads the findings, not the feed. Or let Notifications text you when a source changes.

Source watches
A page, a cadence, a diff in words. The last version is kept so the change is shown, not guessed.
Topic watches
A subject described in a sentence. It finds the sources and files what's new. You don't maintain a list of URLs.
run_checkacme.com/pricingchangeddedupeagainst 23 findings1 newFindings, deduped
The same change reported by six sources is one finding. Noise is the thing a monitor has to be good at removing.
Alerts through Notifications
A change becomes a text or an email, on the channels you keep. Or nothing, and you just ask.
A scope you can read
What's watched, how often, what it found. One screen, no dashboard to admire.
Honestly in beta
It works. It isn't finished. The console says so on every page, and there's a link to tell us what it should become.
It watches what you named. It cannot spam you about it.

Page-change monitors are a mature category with free tiers. Here's what the paid tiers publish.
If you want to watch three pages, Distill's free tier is fine. Ours is $15 for watches that your AI reads and acts on, plus Notifications, CRM and the rest on the same bill. And there is no free tier because a free monitor is one whose checks get throttled when it matters.
