YouTube Keyword Research

Find out how popular your keywords are on YouTube. Give it a keyword and it fans out into synonyms and conceptually similar terms, then searches our database for how many times each has been used in YouTube video summaries and transcripts.

It’s like Google Trends — but for YouTube.

One prompt — the agent fans a seed keyword into related terms and ranks each by real YouTube usage, live in the terminal.

Counted, not estimated

When it says “cold plunge” turns up 12,481 times, that’s a count, not a guess. It’s reading Elasticsearch — our index of the titles, summaries, and transcripts of videos across 1,299,244 YouTube channels, built up over seven years of ingesting what creators actually say on camera. The number is occurrences in real videos.

We didn’t build that corpus for keyword research. We built it to match 61,008 brands to the right creators by topic — and the same transcript search that surfaces every channel talking about your category is what tallies your keywords here. You’re not searching the open web; you’re searching the exact corpus we place sponsorships from.
