Hidden Niche — Personal Content Niche Research Tool
Hidden Niche is a personal, internal command-line research tool that helps its single user (the developer) plan their own video content. It measures content supply and demand for candidate topics by reading public video metadata through the official YouTube Data API v3.
What it does
- Searches public video metadata for candidate topic keywords (
search.list). - Retrieves public video statistics, channel statistics, and channel uploads (
videos.list,channels.list,playlistItems.list). - Reads public top-level comments on those videos (
commentThreads.list) to find questions viewers are still asking, which indicate gaps in existing content. - Optionally reads aggregate keyword search-volume estimates for candidate topics from the developer’s own Google Ads account through the Google Ads API Keyword Planner (
KeywordPlanIdeaService), as an additional demand signal. Read-only: the tool never creates, changes, or spends anything in any Google Ads account. - Computes self-derived aggregate niche scores (supply, demand, competition).
- Outputs reports as command-line text and local markdown files.
The complete list of YouTube Data API endpoints the tool calls is exactly the five above: search.list, videos.list, channels.list, playlistItems.list, commentThreads.list.
What it is NOT
- Not public-facing: no hosted service, no app distribution. This page is the tool’s only web presence.
- No user accounts and no sign-in for anyone else. YouTube data is read with a server API key only (no OAuth). OAuth is used for exactly one purpose: the developer authorizing the tool to read Keyword Planner data from their own Google Ads account (scope
https://www.googleapis.com/auth/adwords). No other person’s Google account is ever connected. - Does not collect, store, or share data about any person.
Access
Command-line only, running locally on the developer’s machine. This page serves as the tool’s public description page for the YouTube API Services compliance review.
