Videolyze

"What are viewers really saying?"

Extracts sentiments, recurring themes, questions and insights from YouTube comments.

Introduction

Videolyze is a defensive API that answers one simple question: "What are viewers really saying?". It returns a deterministic verdict — same input, same output. Always. Zero LLM, stateless, designed to integrate into your automated pipelines.

Input

Send a POST request with a JSON payload. See the example on the right.

Output

The response contains a verdict and explanatory signals. See the example on the right.

Signals

Each response includes a signals object that details the reasons for the verdict. These signals are deterministic and reproducible.

What the API does NOT do

❌Does not moderate comments
❌Does not reply to comments
