Are these YouTube tools really free?

Most are free with no account: the research tools, every generator and the size checkers. The deeper AI checks (Packaging Check, Hook Analyzer, Video Analyzer) use credits; a free account starts with 15.

Where does the data come from?

Public YouTube data through the YouTube Data API. Outlier scores divide a video's views by the median views of its channel's recent uploads. You never connect your channel.

Do the AI tools invent numbers or results?

They're instructed not to. Anything that needs your real results, numbers or experience is left in [brackets] for you to fill in.

How is this different from vidIQ or TubeBuddy?

HookSignals focuses on the decisions before you publish — what to make and how to package it — using videos that beat their own channel as evidence, rather than keyword scores or channel management.
