Reels & TikTok Hook Analyzer

AI & Media Processing

Operated by Sourcelane✓ verified

Analyzes short-form videos (Instagram Reels and TikTok) to reverse-engineer why a clip engages viewers by extracting structured, keyword-rich analysis: verbatim opening hooks and classified hook types and delivery modes; timestamped on-screen text overlays merged into searchable phrases and combined transcripts of overlays; detected calls-to-action with timings and counts; a segment-by-segment, timestamped content structure (e.g., hook → problem → solution → proof → CTA); edit-pacing metrics (scene changes, cuts per minute) and production format signals (talking head, voiceover, music); content-type classification and topic keyword extraction; post metadata and engagement metrics; plus a full verbatim transcript. Outputs are produced as structured records for sorting, filtering and downstream analysis and support videos up to 150 MB.
