Spoiler Alert
Progress-aware spoiler protection for social media and the web.
On-device matching. Spoiler detection runs entirely in your browser. Page content is never sent to our servers.
Spoiler Alert is a Chrome browser extension that hides posts about the TV shows, movies, and sports you're trying to avoid spoilers for. Add titles to your watchlist, set your progress, and Spoiler Alert covers matching posts on supported sites — with optional coverage on any website you opt into.
What Spoiler Alert does

- Progress-aware matching — block spoilers beyond where you are in a series.
- Animated cover themes in Pro — posts stay hidden until you choose to reveal them.
