As answered by people managing JavaScript Operator Lookup and Reelyze.
Reelyze's answer:
Next.js / React (TypeScript) Vercel (hosting) Anthropic Claude (analysis and coaching) OpenAI Whisper (audio transcription) yt-dlp / SocialKit (video retrieval for the tools)
Reelyze's answer:
Most analytics tools report what happened - views, follower counts, posting cadence. Reelyze tells you why. It actually watches your video frame by frame and pairs that reading with your own account data, so instead of a dashboard of numbers, you get the exact line, the exact second, and the exact reason viewers dropped off - plus what to change. It diagnoses a single video in depth rather than tracking many at the surface.
Reelyze's answer:
Tools like Shortimize, Metricool, and Iconosquare track metrics across many videos but don't watch the footage - they can't tell you that your hook at second 2 is where 40% of viewers left. Repurposing tools like Opus Clip turns long videos into clips, but doesn't diagnose performance. Reelyze does the one thing those don't: it explains why a specific short-form video underperformed and gives you a concrete fix. If you want depth on the video you actually posted - not breadth across a feed - Reelyze is built for that. First analysis is free, no card.
Reelyze's answer:
Short-form video creators who post Instagram Reels, TikToks, and YouTube Shorts and want to grow - from solo creators and coaches to small businesses, real estate agents, and social media managers. The common thread is people who are posting consistently but can't tell why some videos take off and others stall, and want data-backed answers instead of guesswork.
Reelyze's answer:
Reelyze started from a simple frustration: creators get plenty of metrics but almost no explanation. You can see a Reel flopped, but not why - was it the hook, the pacing, the payoff? Founder Usama Latif built Reelyze to close that gap, using AI that watches the video the way a viewer does and connects each moment to real retention data, so the answer to "why did this flop?" is specific and fixable rather than a shrug. (Add the real origin - when you started it, the personal moment that sparked it, the weiBlocks connection - to make this authentic.)
