The problem it solves

You post videos but have no easy way to know how your audience really feels beyond likes and views. Reading through hundreds of comments by hand to gauge sentiment takes hours you don't have. You want a clear picture of positive, neutral, and negative reactions without doing the reading yourself.

Who it fits

Best for YouTube creators, social media managers, and brand teams tracking audience sentiment.

How it works

  1. You mark a video as ready in a connected spreadsheet
  2. The system fetches all comments for that video
  3. AI classifies each comment as positive, neutral, or negative
  4. Results are saved to a results tab in your spreadsheet
  5. The video's status is updated so it isn't processed again
What you get

Audience mood tracked comment by comment

You get every comment on your video scored as positive, neutral, or negative and logged straight into your spreadsheet.

What you get

A spreadsheet of every comment tagged by sentiment for each video.

What you need

A Google account, a YouTube API key, and a Google Gemini account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
