Most videos don't fail on content.They fail before anyone presses play.
A viewer decides in a second or two — from a title, a thumbnail and the first line — whether your video is worth their time. Creators spend days on the video and minutes on those three pieces, and usually check them one at a time, if at all.
HookSignals is an independent, founder-built tool for that moment before you publish. It reads your hook, title and thumbnail together, tells you where the promise breaks, and shows real videos on your topic that beat their own channel — so every suggestion comes with evidence you can open and check.
We launched in 2026, we're small, and we'd rather tell you exactly what the tool does than oversell it.
Where the data comes from
Real videos and channel numbers
The public YouTube Data API v3, fetched when you search. Outlier multiples are a video's views divided by the median views of its channel's recent uploads — measured, not estimated.
Written analysis and rewrites
OpenAI language models, prompted to stay on your topic and never invent numbers or results you didn't give. Anything that needs your proof is left as a [placeholder].
Your account and payments
Sign-in by Clerk. Payments by Paddle, which acts as merchant of record, so we never see your card. Your saved reports live in our database and are visible only to you unless you share a link.
