YouTube Transcript Analysis API Skill

📖 Brief

This skill provides an end-to-end YouTube video transcript extraction and deep content analysis service. By extracting video transcripts and then systematically analyzing them, users can understand competitors' core value propositions, target audience profiles, pain point strategies, and content gaps — all without manually watching hours of video.

This skill works in two phases:

1. Phase 1 — Transcript Extraction: Uses BrowserAct API to extract raw transcript data (supports single video and batch modes).
2. Phase 2 — Deep Analysis: The Agent performs structured 8-dimension analysis on the extracted transcripts.

✨ Features

1. No hallucinations, ensuring stable and accurate data extraction: Pre-set workflows avoid AI generative hallucinations, ensuring stable and precise data extraction.
2. No CAPTCHA issues: No need to handle reCAPTCHA or other verification challenges.
3. No IP restrictions or geo-blocking: No need to handle regional IP restrictions or geofencing.
4. Faster execution: Tasks execute faster compared to pure AI-driven browser automation solutions.
5. Extremely high cost-efficiency: Significantly lowers data acquisition costs compared to high-token-consuming AI solutions.

🔑 API Key Guide

Before running, check the BROWSERACT_API_KEY environment variable. If not set, do not take other measures; ask and wait for the user to provide it. Agent must inform the user:

"Since you haven't configured the BrowserAct API Key yet, please go to the BrowserAct Console to get your Key."
