WANT A MODEL TO WRITE IT

Take it to Claude instead

The variants above are instant starting points, assembled in your browser from proven caption structures. They are meant to react to, not to post untouched. If you want a model to write the caption from scratch, generate once above to fill this prompt in with your post and settings, then paste it into Claude or ChatGPT. 

Generate captions above, then this prompt fills in with your post and settings.

Running Claude with an MCP server already? The same brief works as a step in an agent that writes the caption, then schedules it. That is what the Blotato API is for.

FAQ

Instagram caption generator questions

01 Is the Instagram caption generator free?
Yes. No signup, no limits. Generate as many captions as you want.
02 Does it work for Reels and Stories?
Yes. Captions work for feed posts, Reels, and carousels. For Stories, pick the Short length option.
03 Can I add hashtags?
Yes. Toggle the Hashtags option and the generator adds 5 to 10 relevant hashtags based on your topic.
04 Does it use AI?
No, and that is deliberate. It runs entirely in your browser on proven caption structures, so there is no signup, no rate limit, and nothing to wait on. You get 3 variations instantly and edit from there.
05 How is this different from writing captions manually?
It gives you a starting point instead of a blank box. You get 3 structured variations to react to, which is usually faster than writing from scratch. Edit them to sound like you, or use the built-in prompt to have Claude or ChatGPT write them from scratch in your own account.
06 Can I schedule the caption to post automatically?
Yes, with Blotato. Paste the caption, schedule, and it goes live on Instagram (and 8 other platforms if you want).
