Create a product demo video from a script in minutes—no camera or editing required. Add an AI presenter, voice-over, captions, and real product screens, then share one professional demo across sales, onboarding, and support.
Key featuresKey features of the product demo video maker
Scripted demos with AI voice-over
Paste your demo script, and the AI video generator will turn it into a narrated walkthrough featuring a lifelike presenter. Fine-tune the tone, pacing, and emphasis in the text-to-video editor, then regenerate the AI-generated voice-over whenever your product copy changes.
Your real screens, scripted and narrated
Add screenshots, screen recordings, or product images, and choose where each one appears beside the presenter. The walkthrough combines your actual interface with narration and captions, helping viewers understand exactly what the product does as they follow each step.
Edit and update without re-recording
Product updates usually mean reshooting the entire demo. Here, you edit the script with script to video, replace one screen or visual, and regenerate only what changed. Templates and brand settings remain intact, so each version is up to date in minutes.
Localize demos in more than 175 languages
Localize one product demo video into more than 175 languages using AI voice cloning, and lip-sync the dubbing rather than relying on subtitles alone. The presenter speaks each language with matching mouth movements, so a single recording can reach multiple markets without reshooting for each region.
On-brand demos for every channel
Apply your logo, colours, and fonts from a template-based brand kit, then export each demo as an MP4 in HD or 4K. Resize it for your website, a sales email, or social media, and embed or send the same walkthrough on demand.
Use cases
Live demos vary by representative and can be difficult to repeat. Send a consistent, on-demand product demo video that explains the same key features and value every time, so deals can move forward without booking another call.
Recording every workflow by hand eats hours. Use the tutorial video maker to turn step-by-step guides into clear walkthroughs, so new users learn each feature visually and understand the product faster without a live session.
Launches usually need extra recordings and edits. Build the update from a launch script, add narration over the screens, and publish a complete video across your site, email, and multiple social channels on launch day.
New users can get stuck when workflows are confusing. Paste a help document link into the URL-to-video tool to create product walkthroughs that improve activation and reduce the need for scheduled onboarding calls.
Support teams repeat the same answers every day. Turn common questions into short product demo videos that show the solution on screen, reduce ticket volume, and provide customers with relevant self-serve guidance at any time.
Localizing demos region by region is slow. Create one product demo video, then deliver lip-synced versions with the AI Video Translator, so businesses reach every market with a native walkthrough.
How it worksHow product demo video maker works
Create product demos using AI in four steps, from a rough script to a polished, share-ready video you can publish anywhere.
Add your script, or let HeyGen generate one from a topic prompt and outline.
Pick a presenter and voice, or clone your own. Select a template, add captions and background music.
Render the product demo video in minutes. Preview it, then tweak any scene or line and regenerate.
Export as an MP4 in HD or 4K, resize for any channel, or localize into more than 175 languages with one click.
A product demo video maker turns a written script into a narrated walkthrough of your product, without filming. Add a presenter, screenshots, captions, and branding, then generate and edit the entire video from text.
Yes. Upload screenshots, screen recordings, product images, a PowerPoint deck, or a PDF, and add them to any scene alongside the presenter and captions. Each slide becomes a narrated scene, so you don't have to rebuild anything manually.
No camera, webcam, or microphone is needed, and there is no built-in screen recorder. Record with the capture tool you already use, then upload the clip, and HeyGen builds the narrated demo around it, adding a presenter, captions, branding, and translation. You can also create a demo without a presenter, showing only screens, narration, and captions.
Yes. Give HeyGen a topic or a short prompt, and it will write the script, then build a matching storyboard with scenes and narration. You can edit any line in the editor before publishing.
Yes. After switching to HeyGen, Advantive reduced content creation time by 50% and shortened voice-over production from days to just two or three hours across its workforce of more than 600 employees, helping demos keep pace with every product release.
Most run 60 to 90 seconds, which demonstrates the core workflow without losing viewers' attention. Start with the problem, highlight one or two key features, and finish with a clear call to action. For more in-depth feature tours, divide the demo into short chapters that viewers can skip through.
Yes. Start with a demo template, then add your logo, colours, and fonts, along with stock footage, AI-generated B-roll, screenshots, and background music. Templates keep the layout consistent across every video your team creates.
Yes. Captions are generated automatically and can be styled, and you can export a full transcript and description to reuse on your video hosting page. Edit the text and timing so demos remain clear when feeds are muted and meet accessibility requirements.
Yes. Generate the demo once, then create lip-synced versions in more than 175 languages with matching voice and timing. Visuals and branding remain identical across every version. Screen-recording tools capture what you record, but they cannot generate a presenter from a script or localize one afterwards.
You can start for free with no credit card. Paid plans let you export without a watermark and start at $29 per month, or $24 per month billed annually, with custom Enterprise pricing available. HeyGen is SOC 2 Type II certified and complies with the GDPR and CCPA. Data is encrypted in transit and at rest, and your content is excluded from AI model training by default.
