How to use the AI Caption & Hashtag Generator
1
Describe your post
Type a keyword or a short description of what your photo, video or post is about.
2
Choose a platform
Pick Instagram, TikTok or Facebook so the caption length, tone and hashtag count fit that platform.
3
Set tone and length
Choose a tone such as fun, professional or inspirational, and how long the caption should be.
4
Copy and post
Copy a caption, the hashtags, or both together, then edit the wording to sound like you.
Write better social media captions, faster
A good caption does three jobs: it grabs attention in the first line, adds context or personality, and gives people a reason to react, whether that is a like, a comment or a share. This generator gives you several starting points for any topic so you are never staring at a blank box.
Platform differences that matter
Instagram rewards captions that tell a short story or ask a question, and it handles a moderate set of hashtags well. TikTok captions are brief, so the hook and a few precise hashtags do most of the work. Facebook audiences respond to conversational wording and clear calls to action, with only a couple of hashtags. The tool adjusts length and hashtag count to each.
How to use hashtags well
Mix broad tags that many people search with niche tags tied to your exact topic. Avoid unrelated tags that are only popular, since they can attract the wrong audience and look spammy. Re-check each tag before posting to make sure its meaning fits, and keep the count within what the platform recommends.
Make it yours
AI captions are drafts. Add a personal detail, a location or an inside joke, remove anything that does not sound like you, and follow each platform’s rules, including labelling sponsored content.
