Frequently asked questions
Is the tool really free?
Yes. You can generate SEO for your YouTube videos for free, no signup and no credit card. A daily usage limit keeps the tool available to everyone — create a VidiaFlow account for unlimited use.
How does it work?
Paste a public YouTube video URL. The tool fetches the video's captions, analyzes them with AI (the same engine as the full product) and generates 5 optimized titles, a ready-to-paste description, 15-20 tags and an SEO score out of 100.
Does the video need captions?
Yes. The analysis relies on the video transcript. If captions are disabled, or the video is too recent, private or deleted, the tool can't generate SEO. Try another video in that case.
What do I get by creating an account?
A VidiaFlow account unlocks everything else from the same video: blog article, short subtitled clips, social posts, AI-generated thumbnails, and unlimited SEO generation. Free trial.
