FeaturesAI YouTube Shorts Generator features
One prompt to a finished short
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. Adjust any line by editing the text, then regenerate in seconds without reshooting.
AI voiceovers in over 175 languages
Pick 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 a whole faceless channel sounds consistent without you recording a single line.
Auto-captions designed for vertical
Every Short comes back with word-level captions burnt 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.
Long videos into ready-made Shorts
Drop in a podcast, interview, or long upload, and HeyGen finds the moments most likely to keep viewers watching, crops them to vertical, and adds captions. You get several ready-to-post 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
Build 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 speaks your script, so one tool runs 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 out the strongest moments, and returns vertical Shorts with captions, turning one upload into a week of posts.
Story channels rely on strong hooks and consistent output. Generate narrated Reddit-style stories, fun facts, or ranked listicles from a prompt, each with matched visuals and synchronised captions, then spin up the next one quickly.
Marketing teams need short-form adverts more quickly than an agency can film. Paste a product brief into the text-to-video workflow, add a voice and captions, and get vertical promos ready to post straightaway.
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 are conveyed 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 a long video link to repurpose into Shorts.
Pick a voice and language, set caption style, and choose faceless visuals or an on-screen presenter.
HeyGen build the scenes, record the voiceover, and sync 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 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 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 synchronised 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 come across as 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 Programme, so add a clear angle to each video.
You can choose from 300+ natural AI voices and narrate in one of 175+ languages. Voices maintain 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 do both and add a realistic presenter option with Avatar V, plus dubbing into 175+ languages, so one tool covers faceless, presenter-led, and global Shorts.
Yes. HeyGen have 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, whilst 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 native-sounding version. Creators use this to grow the same content across markets without rewriting or re-recording.
