YouTube spoilers in recommendations and thumbnails: SKIP, 35/100 | Ideas Lab

Browser extension that auto-blurs YouTube spoilers in recommendations and thumbnails

The pain

Genuine but niche: spoilers ruin viewing experience for binge-watchers, particularly frustrating on YouTube's algorithm-driven platform where you can't control what appears

The gap

No native YouTube feature exists; third-party solutions are fragmented (manual blocking, limited AI detection)

Build angle

Start as browser extension using ML to detect spoiler-laden thumbnails/titles, blur them automatically with user whitelist controls

Strengths

Clear, relatable problem with passionate potential users
Low technical barrier to MVP (browser extension)
Defensible with ML model trained on spoiler patterns
Could expand to Netflix, Prime, other streaming platforms

Risks

Tiny addressable market, only affects active YouTube users avoiding spoilers (likely <2% of users)
YouTube ToS violation risk; platform could block extension or change API access
Spoiler detection is hard: context-dependent, false positives/negatives damage UX
Difficult monetization: users won't pay subscription; ads don't work on extension
Network effects absent, value doesn't increase with more users
YouTube could build this natively, eliminating market overnight
Requires constant maintenance as YouTube UI changes

Lack of comprehensive subscription platform for Pokémon TCG guides

TCG players love reading guides but hate using Metafy; they desire a Sixprizes-style website offering $20-30/month access to all articles plus strong community interaction.
