captionland
Reels captions are different from feed captions — shorter, hook-first, designed to make people stop scrolling in the first second. The AI generator below is tuned specifically for Reels: 5-15 word outputs, hook-driven openers, and POV / question / declarative formats that perform on the Explore page.

Best Reels caption format: hook (first 3-5 words), payoff (the rest). Hook does the work — payoff confirms the watch was worth it. Examples: 'POV: you're the side character', 'wait for it', 'the bit that broke me'.
Frequently asked
How is this different from the regular caption generator?
Different system prompt + length cap. Reels captions are tuned to be shorter (5-15 words ideal vs feed's 10-30), and biased toward hooks/POVs/questions that drive watch-completion and saves. Same free AI, different brief.
Will it write hashtags too?
Optional. Toggle the 'add hashtags' checkbox and it'll suggest 3-5 relevant Reels-friendly hashtags at the end. Includes one Explore-friendly variant for reach.
Will it match my video's vibe?
Roughly. Add a vibe word in the prompt — 'POV', 'tutorial', 'reaction', 'aesthetic', 'comedic' — and the AI biases the output. The vibe word matters more than the topic.
Are Reels captions different from TikTok captions?
Slightly. Reels captions can be a touch longer because Instagram doesn't truncate them as aggressively as TikTok's first-line cap. But the hook-first principle is identical.
