The AI YouTube Shorts Generator turns a single idea into a finished vertical video. Type a topic to create a faceless Short from scratch, or drop in a long upload to repurpose, and HeyGen handles the script, voiceover, and captions. No filming required.
FeaturesAI YouTube Shorts Generator Features
From a single prompt to a polished short video
Type a topic, paste a script, or share a brief, and the AI video generator writes the script, builds scenes, adds media and a voiceover, and returns a vertical Short. Tweak any line by editing the text, then regenerate in seconds without needing to reshoot.
AI voiceovers in 175+ languages
Choose from 300+ natural-sounding voices or clone your own from a short sample, then narrate every Short in any of 175+ languages. The voice maintains the same tone across clips, so an entire faceless channel sounds consistent without you having to record even a single line.
Auto-captions designed for vertical video
Every Short comes back with word-level captions embedded into the frame, styled for the 9:16 safe zone so text never sits under the progress bar. The subtitle generator syncs each word to the voiceover, and you can restyle fonts, colour, and position with a single click.
Long videos into ready-made Shorts
Upload a podcast, interview, or any long video, and HeyGen automatically finds the most engaging, high-retention moments, crops them to vertical, and adds captions. You get multiple ready-to-post Shorts from a single recording, ranked so you can publish the strongest clips first, without manually scrubbing through the footage.
Go faceless or add a presenter
Create a faceless video using AI visuals, stock footage, and cinematic B-roll, or feature a real presenter on screen. HeyGen converts a 15-second clip into a digital twin that delivers your script, so a single tool can power an anonymous channel or a personal brand.
Use cases
Earlier, growing a channel without filming usually meant hiring editors and voice artists. Now you can simply describe a niche, generate a batch of faceless Shorts with script, voice, and captions, and keep posting regularly without ever showing your face.
Hours of podcast or livestream footage rarely get clipped. The clip generator scans a long recording, picks out the strongest moments, and delivers vertical Shorts with captions, turning a single upload into a full week of posts.
Story channels thrive on strong hooks and consistent output. Generate narrated Reddit-style stories, fun facts, or ranked listicles from a prompt, each with matching visuals and synchronised captions, then get the next one ready quickly.
Marketing teams need short-form ads faster than an agency can shoot them. Paste a product brief into the text-to-video workflow, add a voice and captions, and get vertical promos ready to post quickly.
Teachers and course creators turn dense topics into quick lessons. Enter a concept and get a scripted explainer Short with a clear voiceover and captions, so complex ideas land in under a minute.
One Short can serve every market at the same time. Run a finished clip through the AI video translator to dub it into 175+ languages with matched lip-sync, then post a localised version to each regional channel.
How it worksHow to create AI YouTube Shorts
Go from idea to a posting-ready Short in four simple steps, with no camera, editing software, or production experience needed.
Type a topic, paste a full script, or drop a long video link to repurpose into Shorts.
Select a voice and language, set the caption style, and choose either faceless visuals or an on-screen presenter.
HeyGen creates the scenes, records the voice-over, and syncs captions into a vertical 9:16 cut.
Adjust any line by editing the text, then export a vertical MP4 that is ready to upload to Shorts.
It is a tool that turns a text prompt or a long video into a finished vertical Short. HeyGen writes the script, generates a voiceover, adds captions, and exports a 9:16 clip sized for the Shorts feed, all without any filming or editing software.
Upload the recording or paste its link, and HeyGen scans it for the highest-retention moments, crops each one to vertical, and adds synced captions. You get multiple ranked Shorts from a single video, so you can post the strongest clips first.
Not when the script, visuals, and voice are designed to suit your topic. HeyGen pairs each line with relevant footage or a realistic presenter and natural narration, so Shorts feel like properly produced content rather than a basic slideshow of stock clips and robotic text-to-speech.
Yes. Choose AI visuals, stock footage, and B-roll with a voiceover for a completely faceless Short, and run an anonymous channel from start to finish. If you later want a presenter, you can add one without changing your workflow.
Yes, as long as the content follows YouTube’s rules on original, valuable content rather than low-effort repurposing. Scripted, narrated Shorts with your own edits and commentary are eligible for the YouTube Partner Programme, so make sure you add a clear, distinct angle to each video.
You can choose from 300+ natural AI voices and narrate in over 175 languages. The voices maintain a consistent tone across every clip, and you can match the accent and delivery to your niche, from calm explainer narration to high-energy hooks.
Most tools do only one job: either generate faceless clips or repurpose long-form videos. HeyGen does both and also adds a realistic presenter option with Avatar V, plus dubbing in 175+ languages, so a single tool covers faceless, presenter-led, and global Shorts.
Yes. HeyGen has a free plan you can start without a credit card, and paid creator plans start at $24 per month for more videos, longer exports, and premium voices. You can generate your first Shorts for free to try out the workflow.
Yes. Educator Anton Voroniuk reported saving 15.5 hours per week and cutting production costs by 40x after moving to HeyGen, while reaching over 1 million students. Generating the script, voice, and captions in a single pass removes the slowest steps of short-form production.
Shorts export as vertical 9:16 MP4 files sized for the YouTube Shorts feed, TikTok, and Reels. You control the length so it fits within the under-60-second Shorts window, and captions stay inside the safe zone above the interface controls.
Yes. With AI voice cloning, you can create a copy of your voice from a short sample and use it to narrate every Short. Your channel keeps one easily recognisable voice across languages and clips, without you having to record each script yourself.
Yes. Generate a Short once, then translate it into 175+ languages with lip-synced dubbing so each regional channel gets a version that sounds native. Creators use this to scale the same content across markets without rewriting or re-recording.
