What makes a good YouTube caption
A good caption opens with a hook, delivers one clear idea, and ends with a reason to engage — a question, a call to comment, or a save-worthy takeaway. Length and emoji norms differ by platform, which is why this generator writes natively for YouTube.
How many hashtags should you use
Use a focused set of relevant tags rather than the maximum allowed — a mix of broad and niche tags helps discovery without looking spammy. The generator returns a tuned set you can trim to taste.
Frequently asked questions

Will the captions sound generic?
They are written natively for YouTube from your topic, but they are a starting point — edit in your own voice. Connect your account in BlueKona to generate captions trained on your best-performing posts.
How long should a YouTube caption be?
It varies by platform and goal: short captions suit fast-scrolling feeds, while longer captions can drive saves and comments when the topic warrants depth. Use the length control to match your intent.
