ViralML™ is 100% fine-tuned on hand-picked content that actually went viral. Not scraped, not synthetic. Every transcript was selected by our editorial team, annotated for structure, and trained on our own GPUs in Frankfurt am Main.
General models learned to write from the whole internet, which is mostly content nobody watched. We did the opposite.
Only posts that beat their creator's median by 10× or more. Across TikTok, Reels, Shorts, X and LinkedIn.
Hooks, beats, pattern interrupts, open loops and CTAs, labelled second by second across 460,000 hours.
Full-parameter fine-tuning on our own cluster. No third-party APIs between your brief and the model.
Every checkpoint is scored on SVBench™: real posts, real audiences, blind panels.
