Frequently asked questions
Does the platform matter for captions?
Yes. Instagram requires longer, story-driven captions with strategic hashtag placement. TikTok relies on short, punchy context that forces the user to re-watch the video while reading. Our AI knows the difference.
Do captions affect reach on Instagram and TikTok?
Both platforms read caption text to understand what a post is about, which affects who it is shown to. Captions also drive comments and saves, which are strong engagement signals. A caption is rarely the difference between success and failure, but it is not decorative either.
How long should a caption be?
Match it to the job. A Reel that explains itself needs one line and a question. A carousel that people save as reference benefits from a longer caption that stands alone. Length matters less than whether the first line earns the tap on more.
How many hashtags should you use?
Both platforms have moved toward treating hashtags as topic signals rather than discovery channels. A small number of genuinely relevant tags is fine; thirty loosely related ones mostly signal spam and crowd the caption.
Should the caption repeat what the video says?
No. The caption should add something the video did not: context, a specific number, a question, or the next step. Repetition wastes the one piece of text a viewer will actually read.
