- **Search companion:** next to search results, a keyword score with demand and competition, views per hour by video age, the channels that own the term and the tags the results share.
- **Badges on thumbnails:** views per hour and outlier multiples on search results and related videos.
- **Channel stats:** a quick stats card on every channel page, a full channel panel (recent uploads, posting habits, format mix, top outliers) and a channel audit.
- **Top bar:** your channel's numbers and the Vid0 menu in YouTube's header.

## In YouTube Studio

- **Pre-publish checklist:** title, description, chapters, tags, thumbnail and links, re-checked as you type.
- **Title ideas and description score:** rated title ideas and a description suggestion that keeps your chapters.
- **Forecast check-in:** how a new upload is tracking, with a chart and what to improve.
- **Best time to publish and thumbnail preview:** the hours your last 50 uploads did best, and how your thumbnail looks in the feed, on mobile and up next.

## Privacy

- The page you're viewing stays on your device. The Vid0 API receives only video or channel IDs, never your browsing history.
- Permissions: storage and alarms, plus youtube.com and vid0.in. No access to other sites.
- Read-only: Vid0 never uploads, edits or deletes anything on YouTube.

## FAQ

- **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.
