Caption
Generator.
Three captions for your next post, with real character limits for every platform. Edit, count and copy in one place.
Your captions
Describe the post, pick a platform and tone, and you get three different angles to edit, count and copy.
How to use it
Caption Generator, in 5 steps.
Describe the post in a sentence or two, with the real details: what it is, when, and who it is for.
Pick the platform, a tone, and the action you want people to take. Switch emoji off for a cleaner look.
Press Write 3 captions. Each option takes a different angle, and you can edit it right in the box.
Watch the counter: it uses each platform's real limit and warns when the important part may hide behind see more.
Copy the one you like (or all three) and paste it into your scheduler. Pair it with tags from our Hashtag Generator.
Questions
Good to know.
Is the Caption Generator really free?
Yes. No signup, no email, no limit on template drafts. AI drafts have a fair use cap of 20 per hour so the tool stays free for everyone.
Who writes the captions?
When it is available, an open source AI model (Llama, running on Cloudflare Workers AI) drafts them from only the details you type. If the AI is busy, built in templates write them instead. Either way they are starting drafts, not expert advice, so read them and check every fact before you post.
How long should a caption be?
It depends on the platform. X allows 280 characters, Threads 500, LinkedIn 3,000, Instagram 2,200 and TikTok 4,000, but most feeds only show the first line or two before a see more link. Put the hook and the key detail up front, and the counter on each option shows where you stand.
Why does X count my caption differently?
X weighs characters: most emoji and many Asian language characters count as 2, and every link counts as 23 no matter how long it is. The counter on X options uses those same rules.
Do you save what I type?
No. Template drafts are written in your browser. AI drafts send your topic, platform, tone and call to action to our AI endpoint to write the captions; nothing is stored or used to train a model.
