Key featuresFeatures of the AI reel generator
Script and prompt to reel creator
Describe your idea, paste a text script, or drop in a blog post, and the AI tool generates a vertical video on the spot. Pacing, transitions, and beats happen automatically, so creators get a publish-ready video without an editing tool or text-to-video software.
Auto-captions and on-screen text
Every reel ships with auto-generated captions synced to voiceovers, plus animated on-screen text that still works when the sound’s off. Creators edit burn-ins, fonts and motion to match each brand, then export reels to Instagram, TikTok or YouTube videos with the subtitle generator.
Audio-reactive visuals and beat sync
Upload a track and HeyGen reads the tempo, mood, and phrasing to drive cuts, dynamic transitions, and high-energy visual effects. Hits land on the beat, music and sound effects build on the drop, and captions snap to lyrics for dramatic, on-trend music promos.
Voice cloning and AI voice-overs
Clone your voice from a 30-second sample, or pick from natural-sounding AI voices for voiceovers, and keep one consistent delivery across every reel. With AI voice cloning, creators and brands keep a single narrator identity across a content calendar without re-recording.
Localised reels in any language
Translate any reel into 177+ languages and dialects with lip-synced voice, accurate captions, and culturally adapted phrasing for every market. The AI video translator keeps your delivery and timing intact, so one creative can ship globally in an afternoon instead of weeks of dubbing.
Use cases
Create production-grade videos every day without filming. Type a hook, choose a style, and the AI tool generates vertical video clips for Instagram Reels, TikTok, and YouTube Shorts so every creator posts consistently.
Drop in a product URL and the AI reel maker pulls imagery, builds product demos, and creates shoppable brand videos. Spin ad clip variants with the promo video workflow for paid social and brand campaigns.
Run a faceless brand or commentary channel and create reels without a camera. HeyGen pairs cloned voice with B-roll clips, animated text and stock footage, so a script becomes a polished, on-trend video.
Create reels at scale and generate dozens of testimonial-style UGC videos from a script using realistic AI presenters. The AI ad maker batches variants for split testing on Meta, TikTok, and Reels without having to book creators.
Turn lessons, tutorial videos, and how-to guides into captioned reels for Instagram Reels or Shorts. Create reels from long lectures, generate narration, and localise each video for global audiences in any language.
Upload a track and HeyGen instantly builds audio-reactive lyric reels where captions match the phrasing and dramatic visuals land on the drop. Artists and labels create standout release videos without hiring a video editor.
