Know what your competitors ship — before your customers do.
Rivvie watches their changelog, pricing, and feature pages. When something meaningful changes, we summarize it and drop it in your inbox. Not in a spreadsheet. Not on Monday morning.
No credit card. Cancel any time. We email you only when something matters.
You're losing the competitive race to a 30-tab browser session.
Every week you open the same competitor pages: their changelog, their pricing, their /features. You scroll, looking for what's new. You miss things. You forget which page changed last week. You wonder if the marketing tweak you didn't notice was actually a strategic pivot.
Rivvie does the boring part. You see only what changed, summarized in a sentence.
Three steps. Then it's hands-off.
Add competitor URLs
Their changelog, /pricing, /features, blog index — anything HTML. Optionally narrow to a CSS selector to skip nav and footer.
Rivvie watches — quietly
We re-fetch every few hours, normalize the page (no nav/footer noise), and diff against your last snapshot. We respect rate limits and identify ourselves with a clear User-Agent.
You get the headline
Claude reads the diff and tags each change as major, minor, or trivial. Daily email digest, dashboard view, full diff one click away.
Built around the signal, not the noise.
Severity-tagged summaries
Every change is automatically classified. New pricing tier? Major. Reformatted blog post? Trivial. Your inbox shows the first; the dashboard surfaces the rest.
Boilerplate-free diffing
We strip nav, footer, scripts, cookie banners, and dynamic timestamps before comparing. The diff you see is the diff that matters — no "page updated" false positives.
One email a day
Major and minor changes from across your watchlist, grouped by severity. Trivial changes stay on the dashboard so the email stays short.
Full diff, one click
Click any change to see the unified diff — added lines green, removed red — alongside the AI summary. Verify what we found before acting on it.
Scans every few hours
Free plan checks every 6 hours. Paid plans check hourly. You can also click "Scan now" on any source for an immediate refresh.
Your data, your control
Snapshots and AI summaries live in your account. Delete a source and its history is gone. Export anytime — every change has a permanent URL.

Everything else
How does Rivvie know what's "important"?
We send the diff to Claude with a system prompt that knows what indie SaaS founders care about: new features, pricing changes, new tiers, executive moves, big positioning shifts. Reformatting and dynamic timestamps get tagged trivial and skip the digest.
What about JavaScript-rendered pages?
Today Rivvie reads the server-rendered HTML. Most changelog and pricing pages render server-side, so this works for the vast majority of sources. Headless browser rendering is on the roadmap for SPA-only competitors.
Will competitors know I'm watching?
Our scraper sets a clear User-Agent (RivvieBot/1.0) so site owners can identify it in their access logs if they look. We don't try to hide. We also enforce a 20-second timeout and 2 MB cap per page so we never hammer anyone's site.
What happens when a page goes down or changes layout?
Failed scans are tagged "error" on your dashboard with the reason. The next successful scan reconnects automatically. If a layout change adds noise, you can scope the watch to a CSS selector.
Can I export my data?
Every change has a permanent URL with the AI summary and raw diff — bookmark or share any of them. Daily digest emails act as an ongoing record in your inbox. A bulk CSV export is on the roadmap.
Who builds Rivvie?
One indie founder. No VC, no growth team, no sales reps. The pricing reflects it. If something's broken or you have a feature request, you're emailing the person who writes the code.
