Three to pick from
Every write gives you three different captions, so you can choose the one that sounds most like your brand.
Hashtags sized right
The hashtag set follows each app's habits: 3 to 8 on Instagram, 3 to 5 on TikTok, fewer on X and Threads.
Fits the character limit
Each caption shows its length, and caption plus hashtags always fit the app you picked.
A two-person candle shop is dropping a winter scent on Friday and has ten minutes before the next order run. They type "new cedar and orange candle drops Friday, small batch", pick TikTok and Bold, and get three short hooks plus five tags to post with the clip.
