Autopilot
Give it your video — or a topic you're planning — and it runs every check on its own: your stats against your channel, competitors, search demand, keywords, comments and upload timing. Then it writes the titles, description, tags, thumbnail brief and a growth plan.
Auto Run → Google Sheet
Hands-free. It finds topics on YouTube, checks each one against real search demand and competition, writes the title, description, tags and thumbnail brief, and puts every row into your Google Sheet. Or it fills in the rows you add to the Sheet yourself.

Turn a broad interest into ranked, specific video niches for the USA and Europe. Every topic is scanned live on YouTube — demand, outliers, how open it is to small channels, search interest and ad value.

How the Opportunity score works
Note: YouTube's API can't filter by where viewers live, so a market here means videos available there plus that market's language. Search suggestions and RPM are truly market-specific.
Keyword explorer
Real YouTube search-box suggestions per market — what viewers in the US and Europe actually type. Free: uses no API quota.
Outlier finder
Videos that crushed their own channel's normal views — proven topics you can make your own version of. Small-channel outliers are the easiest to copy the pattern of.
Rising now
The fastest-climbing new uploads per market and category — catch a topic while it's still rising. YouTube retired its Trending page in 2025; this rebuilds it with search.
Recreate a thumbnail
Take any winning thumbnail and rebuild its visual formula for your own topic.
Generate from a title
Pulls the top competitor thumbnails, finds what drives their clicks, then generates thumbnails built to beat them.
Edit a thumbnail
Describe what to add, remove or replace. Pick a result and edit it again to iterate.
Competitors & thumbnails
Search with your planned title or any keyword. 🚀 marks outliers — videos pulling more views than their channel has subscribers. Download any thumbnail in full resolution, or all of them as a .zip.
Reach check
Check before you film: is YouTube still giving this topic impressions? Recent winners and losers are sampled and every video is measured against its own channel size.
