Refreshing competitor tabs is not a competitive intelligence program
Most teams find out a rival cut prices or shipped a feature when a sales rep loses a deal over it. By then the battlecard is already wrong. Google Alerts misses anything that never becomes a press release — which is most of what changes on a website.
- •Silent pricing changes: a competitor drops a tier from $499 to $399 and never announces it. Your reps quote the old number.
- •Quiet positioning shifts: the homepage headline changes, a category gets renamed, a new ICP shows up in the nav — signals your messaging should answer.
- •Feature drops: a changelog or "what's new" page updates before the press cycle. You want it in the battlecard first.
- •Hiring tells: new roles on their careers page reveal where they're investing months before the market notices.
How it works
Tell us which pages to watch
Paste the exact URLs — pricing, product, careers, changelog, a specific competitor's blog. You decide the watchlist, down to the page.
Watch a single page or a whole section.
Our agent checks them on your schedule
sieve re-reads each page and understands it semantically, so a layout redesign or a moved div doesn't trigger a false alarm — and a real change never slips through.
Survives site redesigns that break scrapers.
You get the diff where you work
A clean, human-readable alert — what changed, old value vs. new — lands in your inbox, Slack, or as a text. Drop it straight into a battlecard.
Email, Slack, or SMS.
Watch pages, not the whole internet
This isn't a media-monitoring firehose. You curate the sources; we watch only those. Signal, not noise.
Catches changes no press release covers
Pricing edits, swapped testimonials, a removed feature, a new logo on the customers page — the quiet stuff that never hits the news.
Human-verified, so alerts are trustworthy
Every flagged change is checked before it reaches you. No "the CSS changed" false positives that train you to ignore alerts.
Battlecard-ready summaries
Each alert says what moved in plain English, with before/after — paste it into Klue, Crayon, a wiki, or your sales channel as-is.
What competitive intelligence teams watch
- Competitor pricing and packaging pages — every tier, every number
- Homepage and category pages for positioning and messaging shifts
- Changelogs, release notes, and "what's new" pages for feature drops
- Careers pages — headcount signals by team and geography
- Customer / logo pages to catch new marquee wins and churned logos

Questions people ask
Google Alerts only catches things that get indexed and mostly surfaces news articles and blog posts. It will never tell you a competitor quietly changed a number on their pricing page. sieve watches the actual pages you choose and reports the on-page change itself.
No. The agent reads pages by meaning, not raw HTML, and a human verifies a change is real and material before it reaches you. A redesigned page that says the same thing is not an alert.
You set the cadence per watch — from a few times a day to weekly. For fast-moving pricing or launch pages, run them more often; for stable pages, less.
Public pages work out of the box. Gated pages are sometimes possible depending on the site — tell us the URL and we'll be straight with you about what's feasible.
