Track competitor pricing pages on your watchlist. Email alerts when prices or tiers change. Privacy by default. pricepulse turns "I should keep an eye on their pricing page" into a one-click subscription. 1. Add. While you're on a competitor pricing page, click the pricepulse icon and the page joins your watchlist. Optionally give it a nickname. 2. Watch. Our backend re-fetches each URL on your tier's schedule (weekly free, daily Pro, hourly Pro+). The page is fetched server-side — your browser is never the user-agent, no proxy, no scraping from your computer. 3. Diff. When the page text changes against the previous snapshot, you get a one-line summary email and a deep-link to a side-by-side diff with token-level highlights. If nothing changes, you don't get an email. Free tier: 5 watchlist entries, weekly checks, rolling 30-day snapshot history, full diff viewer, email alerts. No card to start. Pro ($4.99/mo): 50 entries, daily checks, unlimited history, CSV export of any timeline, AI tier & price extraction (one click on a snapshot — get a structured list of plan-name / price / interval / featured-flag). Pro+ ($12.99/mo): 500 entries, hourly checks, Slack & Discord webhooks (route alerts into a team channel), JSON read-API (drive your own dashboard from any pipeline you already run). Privacy by default: the extension only stores your watchlist URLs, an optional alert email, and a 24-character random install-id used for free-tier rate limiting. No browsing-history collection, no analytics, no fingerprinting. Full policy at extensions.voiddo.com/pricepulse/privacy. Built by vøiddo, a small studio shipping AI-flavoured tools, browser extensions and weird browser games.
