Only the changes you actually asked for.
Track any URL — manga chapters, YouTube uploads, job listings, blog posts. Describe what matters in plain English; AI reads every change and stays quiet unless it matches. Checked daily on Free, every 6 hours on Pro.
How it works
Paste a URL
Any public webpage — a manga site, a YouTube channel, a job board, a blog. If it has a URL, SurveiLN can watch it.
Describe the watch
Tell us in plain English what to watch for — AI-powered, so it understands. No selectors, no regex, no setup.
Get notified
We check on a schedule, with an extra push for YouTube and blogs when the source supports it (Pro and Power). The moment something matches, you get a push or an email.
What people track
Built for things that update a few times a day — the stuff you'd otherwise check by hand.
Why it doesn't cry wolf
AI-powered extraction
Byte-diff tools cry wolf on rotating ads and timestamps. When a page changes, AI judges whether it matches what you asked for — so an alert means something happened.
A cadence you can count on
Every tracker is checked on a fixed schedule — every 3 hours on Power, 6 on Pro, daily on Free. Where a source publishes an update feed we subscribe to it as well, which can arrive sooner, but the schedule is the guarantee.
Push + email, every plan
A push for the chapter you've been waiting on, an email for the slow-moving stuff. Both included on every plan, Free included.
RSS auto-detection
Paste any URL and SurveiLN finds the cleanest way to watch it — RSS feed, WebSub, or a plain scrape. You never pick a method.
Simple, transparent pricing
Start on Free — no card required. Upgrade to Pro or Power from the pricing page once you're in, and change or cancel any time.
