Scores arrive with cited signals and a counterfactual for what would have made them fail, and the pre-publish check runs an adversarial pass against your own draft. That is the difference between a number you argue with and one you can act on.
A short-form content research server over TikTok, Instagram and YouTube: creators analysed, videos searched, templates and rising trends surfaced, hooks scored and rewritten, viral structures remixed for a new topic, and a draft checked before it ships. Calls cost credits, and each tool's cost is published.
- A creator taken apart by handle or channel ID — viral DNA, replicability, originality, consistency and audience fatigue scores, format fingerprint, top recent videos with transcripts, content gaps, and the single largest quantified performance gap as a headline insight
- A draft hook scored 0-100 with its percentile rank, the pattern it matched, what is working and what is not, and three stronger rewrites
- Keyword search across TikTok or Instagram returning up to 20 videos ranked by engagement, with views, likes, shares, comments, hashtags and author, filterable by niche, minimum views, recency and region
- What is rising in a niche right now — formats, hooks, styles and topics with growth signals and their sources — and the patterns already saturated
- Proven templates for a niche ranked by performance, with hook patterns, structures, average views and example URLs
- A viral video turned into a fresh script for your own topic: the extracted formula, scene by scene with voiceover, visuals, camera directions and text overlays
- A creator's voice extracted from three or more samples — energy, humour, vocabulary, signature phrases — and your draft rewritten in it, with reusable prompt instructions
- A finished draft scored for virality with an adversarial check, returning ship, rework or no-go, the evidence behind the breakdown, and the attack vectors against it
- A brand brief turned into a one-page blueprint in a single call: hook, template, hashtag combination, trend-velocity check and shoot instructions
