Free reference libraries for short-form video teams
Mentis resources are public references for short-form creators, editors, and growth strategists. Use them alongside paste-a-link analysis on the homepage when you need hook inspiration, psychology framing, or concrete examples before you brief an editor or send a creative to paid social.
Everything here is designed for teams that ship TikTok, Instagram Reels, YouTube Shorts, Facebook video, and X clips weekly—not one-off vanity checks. Browse open libraries without a login, then sign in when you want deeper access or to run structured video intelligence on a specific URL or upload.
Viral hooks library — search by category and psychology
The viral hooks library catalogs more than 4,000 proven openers for TikTok, Instagram Reels, and YouTube Shorts. Each entry includes example phrasing, psychology notes, and tags so you can compare patterns to your own drafts instead of guessing what made a competitor clip stop the scroll.
Filter by content category, psychological trigger, or keyword to find curiosity gaps, pattern interrupts, social proof frames, and contrarian angles that fit your niche. Editors use the library to rewrite weak first seconds; strategists use it to build hook matrices for UGC briefs and influencer outreach before a shoot day.
Free tools by platform
Interactive analyzers live under Free tools, organized by platform: TikTok, Instagram, Facebook, X, and YouTube. Each folder lists a keyword niche analyzer and paste-a-link video analyzer where available — no sign-in required.
Platform niche analyzers — keyword research without sign-in
Free niche analyzers estimate demand, saturation, and monetization for any topic keyword — powered by the Mentis social world catalog, not live platform API pulls:
- YouTube Niche Analyzer
- TikTok Niche Analyzer
- Instagram Reels Niche Analyzer
- Facebook Video Niche Analyzer
- X Video Niche Analyzer
Enter a topic like “artificial intelligence” or “meal prep” to get catalog-backed scores, sub-niche ideas, and whitespace opportunities. Results appear instantly on the page and are not saved — no account required.
Pair hook research with paste-a-link video analysis
Reference libraries answer “what hooks exist?” Mentis analysis answers “how does this clip perform?” Paste a supported URL or upload a file to get structured scores on pacing, retention signals, sentiment, on-screen text, captions, and cross-platform fit. That combination helps you move from inspiration to iteration: pick a hook pattern from the library, draft your variant, then validate whether the first three seconds actually land.
Product and growth teams also use Mentis for creator analytics, hook optimization, and audience retention insights when reporting to clients or internal stakeholders. See the full capability map on the product overview or compare plans on pricing. Common workflow questions are covered in the FAQ.
Who uses Mentis resources
Solo creators bookmark hook categories before batching content. Agency editors share psychology tags with clients to explain why a rewrite will perform better. In-house growth teams pair the library with competitor benchmarking so monthly creative reviews start from evidence, not taste alone. Brand and compliance teams still run full Mentis analysis when they need brand safety, authenticity checks, or forensic review on a specific asset.
