YouTube descriptions live or die on the first two lines — that's all that shows up under your video before the 'show more' fold. The AI generator below is tuned specifically for YouTube: hooky first lines, full descriptions with timestamps and CTA, and 5-10 keyword tags. Free, no login, no email gate.

Frequently asked
How is this different from the Instagram caption generator?
Different system prompt + length cap. YouTube descriptions are tuned to be longer (300-500 words ideal vs IG's 1-2 lines), with hooks for search-driven discovery, and they include a CTA + chapter markers when appropriate. Same free AI, different brief.
Will it write the title too?
Yes. Toggle the 'add title' checkbox and it'll suggest 3-5 title options optimized for YouTube search — high CTR phrasing without clickbait.
Can I use the captions commercially?
Yes. You own anything you generate. The tool is essentially a polished, YouTube-specific prompt-engineered LLM. No watermark, no attribution required.
Will it generate tags / keywords?
Yes — at the end of every description it appends a tag block with 5-10 keywords relevant to the topic. Toggle off in the extras field if you don't want them.
