Build a viral hook library from the TikToks you study
Every serious creator knows: the first three seconds decide whether the video gets watched. You've been saving scroll-stoppers for months to figure out what works. Sftir turns those saves into a structured Hook Library — every opening line, pattern, and format extracted and searchable. Study what works. Adapt what resonates.
How sftir helps
Automatic hook extraction
Every TikTok you save on the Creator tier gets its opening hook pulled out and filed. Over weeks, you build a growing archive of first lines that made you stop scrolling.
Searchable by pattern
Filter hooks by type — curiosity gap, bold claim, pattern interrupt, question hook. Search by keyword ('nobody talks about,' 'I spent 6 months'). See which patterns are dominating right now.
Compare hooks against performance
The transcript + metadata gives you the full context — what the hook was, what the video was about, how the creator built on it. Study the whole package, not just the line.
How it works
Save the TikToks that stopped your scroll
Your Hook Library builds itself from your normal saving behavior — no extra workflow, no manual logging.
Sftir extracts the opening
The first beats — the hook — are pulled from the transcript and filed. Pattern classification is automatic.
Browse, search, and riff
Open your Hook Library when you're writing your next script. Scan the patterns that are working. Adapt the structure to your own voice.
For the full-time content creator
Jordan posts 3–5 TikToks a week in the finance niche. Before Sftir, his 'hook file' was a messy Notes doc. Now his Hook Library is 400+ hooks deep, auto-filed by type, searchable by topic. When he's stuck on a script, he opens the library, filters by 'bold claim,' and has ten reference patterns instantly.
Frequently asked questions
Is Hook Library included in all plans?
The Hook Library is a Creator-tier feature ($79/mo, unlimited videos). Lower tiers get the transcripts and summaries, but the dedicated hook extraction and pattern classification is Creator-only.
Can I export my Hook Library?
Yes. Export to CSV or JSON, or pull via API. Build your own hook-pattern tooling on top if you want.
Does it detect hooks in non-English content?
Yes — Sftir handles multilingual transcripts, and hook extraction works on whatever language the video is in. Patterns translate, so cross-language study is useful for trend spotting.
Will Sftir write hooks for me?
No. Sftir surfaces the patterns and helps you study them. Writing your own hook in your own voice is the whole point — the Hook Library is the reference material, not the author.
