How It Works

About the YouTube Video SEO Tool

A free AI tool to generate production-ready YouTube metadata from your video script in one click.

📥

1. Input Your Script

Paste your video script directly or upload a PDF, TXT, SRT, or DOCX file (up to 5MB). SRT files also generate real chapter timestamps from the subtitle timing.

🤖

2. AI Analyzes It

GPT-4o detects your content niche, search intent, emotional trigger, and primary keywords. It applies YouTube-specific SEO rules — not generic content writing.

✂️

3. Copy and Upload

Every section is copy-ready with one click. Regenerate any section you want a fresh take on. Use "Copy Everything" to copy title, description, and tags in YouTube Studio format.

Frequently Asked Questions

What files can I upload? +
PDF, plain text (.txt), SRT subtitle (.srt), and Microsoft Word (.docx) — up to 5MB. If PDF text extraction fails (some PDFs store text as images), paste the content directly in the text area.
How are titles scored? +
Each title is scored 1–10 on four signals: keyword placement (primary keyword near the start), character count (ideal range 40–70 characters), emotional pull (urgency, curiosity, or value promise), and uniqueness (differentiation from generic title patterns). The overall score is the average.
What is the "above the fold" preview? +
YouTube shows ~157 characters of your description before the "Show more" button on desktop. The fold preview mode splits your description visually at that cutoff — yellow = visible, gray = hidden. Putting your primary keyword and strongest hook in the visible section improves both CTR and SEO indexing.
Why 15–20 tags instead of just 500 characters of tags? +
YouTube's algorithm no longer relies heavily on tags for discovery — but they do help with "watch next" recommendations by signaling topic clusters. The tool uses a tiered approach: 3 broad tags anchor the topic, 8 mid-tail tags capture search variations, 5 long-tail tags catch niche queries, and 4 channel-brand tags build topic authority on your channel.
Can I regenerate individual sections? +
Yes. Every section has a ↻ Regenerate button. The regeneration uses your original script plus the detected niche/keyword context to produce a fresh variation — so it stays consistent with the overall metadata even when you replace individual pieces.
