What you’d write
Paste the series page. SurveiLN works out which links on it are chapters, remembers the ones already there, and tells you about the ones that appear later.
mangareader.io/one-piece“Alert me when a new One Piece chapter is posted”
You get: “Chapter 1121 just dropped on Manga Reader.” — with a link straight to it.
Ignored: the sidebar of other series’ latest updates, which rotates every few minutes.
webtoons.com/en/…/list“Tell me when a new episode goes up”
You get: One notification per new episode, named, in the order they appeared.
Ignored: view counts, the “trending” rail, and the banner image changing.
mangadex.org/title/…“Only tell me about official English releases”
You get: The chapters matching that description — the rest stay quiet.
Ignored: fan translations in other languages posted the same hour.
How often it checks
Every 3 hours on Power, every 6 on Pro, once a day on Free. Chapters do not appear on a schedule, so what matters is that a check happens a few times a day — not that it happens the second the page changes.
Free checks once a day at a time you pick, Pro every 6 hours, Power every 3. See the plans →
Where it struggles
- Reader sites behind Cloudflare’s “checking your browser” wall can’t be read. SurveiLN tells you that outright rather than sitting there silently.
- A few readers build the chapter list in the browser with JavaScript. Those pages arrive empty, and the tracker reports that instead of pretending nothing changed.
- Aggregator pages that mix many series can be noisy. Track the series page itself and SurveiLN scopes to that series’ own chapter links.
