Know if a topic is worth making before you search twice

Next to every search: a keyword score with demand and competition, views per hour by video age, and whether the term is winnable at your channel's size.

It runs on youtube.com and talks to vid0.in. No access to any other site.

Read-only on YouTube

It never uploads, edits or deletes anything. You stay in control of your channel.

Questions

Good to know

Is the extension free?

Yes, on every plan. Lookups that use AI or keyword research count against your plan's limits, the same as in the web app.

What does it send to Vid0?

The IDs of the videos and channels on the page, so we can look up their public stats. The page itself, your history and your searches stay on your device.

Does it work next to vidIQ?

Yes. Vid0 picks spots that leave room for other extensions, and stacks above them where they share a column.

Does it follow dark mode?

Yes. It follows YouTube's own theme, light or dark.

Why does it need youtube.com and vid0.in?

youtube.com is where it draws its cards; vid0.in is the Vid0 API and the page that connects the extension to your account.
