AI reel generator: from one prompt to a voiced reel
Type what your reel is about. The AI writes a script that sounds spoken, records it in a natural voice, times captions to every word, scores it and cuts it to the beat, using your photos if you add them.
- AI voice-over
- Word-by-word captions
- MP4, 1080 x 1920
A reel, not a slideshow
A good reel has a hook in the first second, a voice that sounds like a person, captions people can follow with the sound off, and cuts on the beat. SocialKit's AI handles each part: it writes the voice-over to be spoken, not read, records it in one of its house voices (or a native speaker for Indian languages), aligns the captions word by word, writes music for the mood, and cuts your photos or kinetic type to it.
Three formats suit different posts: "You in front" puts your cut-out in front of big words, "Kinetic type" makes the words themselves the visual when you have no photos, and "Photo dump" cuts quickly through all your photos with sticker captions.
How to make a reel with AI
- Step 1
Write one prompt
What the reel is about, in a sentence. Add photos for a photo-led reel, or leave them out for kinetic type.
- Step 2
Choose the language and length
Auto, or about 15, 30 or 45 seconds. Voices in English and 13 Indian languages.
- Step 3
Let the AI produce it
Script, voice-over, captions, music and edit, ready to preview in the studio.
- Step 4
Render and post
Switch the format or the music, then render an MP4 for Instagram, Facebook or YouTube.

Tips for reels people watch to the end
- Lead with the most surprising line. The AI puts your hook first, so make the prompt's best point clear.
- Keep it short: 15 to 30 seconds holds attention best for most topics.
- Add three or more photos for a photo dump; one clear photo of yourself for "You in front".
- Captions matter: most people watch with the sound off, so every word is on screen.
- Post the carousel version too. Choose "Both" to get both from one prompt.

Everything you need to know about formats, specs, and how it works.
01Is the AI reel generator free?

04Where can I post it?
It is a standard vertical MP4 for Instagram Reels, Facebook Reels and YouTube Shorts.
05Do I need photos?
No. Without photos the reel uses kinetic type on your colours.
