Questions
How long can a TikTok caption be?
Up to 4,000 characters, but only about the first 100 are visible on the video. Most captions work best in one or two lines.
Does it write hooks for the video itself?
Ask for it in the description, for example “also give me on-screen text for the first 3 seconds”.
Should I use #fyp and #foryou?
They say nothing about your topic. Two or three tags that describe the video help TikTok find the right viewers.
Can I get captions for a photo carousel?
Yes. Say it is a carousel and the caption will invite people to swipe through the photos.
Can AI SMM post to TikTok?
Yes, videos and photo carousels on schedule, with views, likes and followers in analytics. Long videos can be cut into vertical clips in the video clipping app.
