The AI YouTube Shorts Generator turns one idea into a finished vertical video. Type a topic to build a faceless Short from scratch, or drop in a long upload to repurpose, and HeyGen handles the script, voice, and captions. No filming needed.
FeaturesAI YouTube Shorts generator features
One prompt to a finished 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 reshooting.
AI voiceovers in 175+ languages
Choose from 300+ natural voices or clone your own from a short sample, then narrate every Short in one of 175+ languages. The voice keeps the same tone across clips, so an entire faceless channel sounds consistent without you recording a single line.
Auto-captions designed for vertical video
Every Short comes back with word-level captions burned 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 in a click.
Turn long videos into ready-made Shorts
Drop in a podcast, interview, or long upload, and HeyGen finds the moments that keep viewers watching, crops them to vertical, and adds captions. You get several posting-ready Shorts from one 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 with AI visuals, stock footage, and cinematic B-roll, or put a real presenter on screen. HeyGen turns a 15-second clip into a digital twin that delivers your script, so one tool can power an anonymous channel or a personal brand.
Use cases
Growing a channel without filming used to mean hiring editors and voice artists. Describe a niche, generate a batch of faceless Shorts with script, voice, and captions, and post consistently without ever showing your face.
Hours of podcast or livestream footage rarely get clipped. The clip generator scans a long recording, pulls the strongest moments, and returns vertical Shorts with captions, turning one upload into a 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 matched visuals and synced captions, then spin up the next one quickly.
Marketing teams need short-form ads faster than an agency can film 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 once. 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 steps, with no camera, editing software or production experience required.
Type a topic, paste a full script, or drop in a long video link to repurpose into Shorts.
Pick a voice and language, set the caption style, and choose faceless visuals or an on-screen presenter.
HeyGen builds the scenes, records the voice-over, and syncs captions into a vertical 9:16 cut.
Tweak any line by editing the text, then export a vertical MP4 ready to upload to Shorts.
It’s 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 filming or editing software.
Upload the recording or paste its link, and HeyGen scans it for the moments most likely to keep viewers watching, crops each one to vertical, and adds synced captions. You get several ranked Shorts from one video, so you can post the strongest clips first.
Not when the script, visuals, and voice are built to match your topic. HeyGen pairs each line with relevant footage or a realistic presenter and natural narration, so Shorts feel like produced content rather than a slideshow of stock clips and robotic text-to-speech.
Yes. Choose AI visuals, stock footage, and B-roll with a voiceover for a fully faceless Short, and run an anonymous channel end to end. 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 Program, so make sure each video has a clear angle.
You can choose from 300+ natural AI voices and narrate in more than 175 languages. Voices keep a consistent tone across every clip, and you can match accent and delivery to your niche, from calm explainer narration to high-energy hooks.
Most tools do one job: either generate faceless clips or repurpose long videos. HeyGen does both and adds a realistic presenter option with Avatar V, plus dubbing into 175+ languages, so one 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 begin at $24 per month for more videos, longer exports, and premium voices. You can generate your first Shorts for free to test 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 1M students. Generating script, voice, and captions in one 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 to fit 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 recognisable voice across languages and clips without you recording each script.
Yes. Generate a Short once, then translate it into 175+ languages with lip-synced dubbing so each regional channel gets a natural-sounding local version. Creators use this to grow the same content across markets without rewriting or re-recording.
