YouTube Caption Generator FAQ
How does the AI YouTube caption generator work?
You describe the video and the AI drafts titles and a description from it, using the plain words people search for. It doesn't see YouTube's data or what is trending, so compare your title with the suggestions in YouTube's own search box.
Does it help with YouTube SEO?
It can help with the words. The draft uses your topic's keywords in the title and description, but it doesn't see YouTube's search data, so compare it with the suggestions in YouTube's own search box before you publish.
Can I generate YouTube Shorts captions?
Absolutely! Select 'Shorts Caption' as the content type for short-form content. The AI adapts to Shorts' vertical format requirements, creating punchy titles and descriptions optimized for the Shorts shelf and mobile viewing experience.
What makes a good YouTube description?
A clear first line or two (they show in search and before "more"), what the video covers, timestamps if you want chapters, links and a call to action. The AI drafts the summary and the call to action from your description; add timestamps and links yourself, since it doesn't watch the video.
Should I include hashtags in YouTube descriptions?
Yes. YouTube shows up to 3 hashtags from your description by the title, and ignores all hashtags on a video that has more than 60. Use 3-5 relevant hashtags for better discovery without appearing spammy. Our generator suggests hashtags based on your video topic; check them against what people actually search.
How long should YouTube titles be?
Keep titles under 60 characters to avoid truncation in search results and suggested videos. Front-load important keywords and emotional triggers in the first 40 characters. Our AI optimizes title length while maximizing click-through rate potential.
Can I generate video tags?
Yes! Our tool suggests relevant tags based on your video topic, including a mix of broad and specific terms. Tags help YouTube understand your content for recommendations. The AI prioritizes tags with high search volume and low competition.
Is there a limit to captions I can generate?
Each generation uses AI credits from your PostNext plan: 10 a month on the free plan, 150 on Premium and 500 on Business. Generating needs an account, and new accounts start with a 7-day free trial that asks for a card.
