Frequently asked questions
What exactly does HookIQ do?+

Is it really free?+
Yes. Every account gets 10 full analyses per month with no credit card. Paid plans unlock higher volume, thumbnail vision analysis and saved history.
Which platforms does it support?+
TikTok, Instagram Reels and YouTube Shorts. You switch platform context and re-score instantly since each algorithm rewards different things.
How is this different from Virlo or VidIQ?+
They track what other creators already posted. HookIQ scores YOUR content before you post it, rewrites it, and gives you a shareable result page. It's radar, not a rear-view mirror.
What AI model powers the scores?+
A fast, capable vision model tuned with a short-form virality rubric so results are specific and consistent, not generic.
