Short videos for business, made from your website
Free AI video generator: paste your website, get business videos free for 7 days
Paste your website into this free AI video generator and get short vertical videos about your business, free for 7 days on the trial. You approve each one and Postdom posts it, so you get video on social media without filming or editing.
A free AI video generator makes video from an input such as a prompt, a script or a website. Postdom is an AI social media tool that turns your website into short videos, slideshows and posts, then publishes them. Its input is your business website, and its videos are short 9:16 posts with a hook, matched clips and music.
Videos Postdom's AI has made
Nine finished videos for sample businesses in nine styles, labelled with the style and the trade, from a gym to a hotel.
Real Postdom posts for sample brands, which aren't real businesses. Clips and photos are licensed stock or made with AI, as in the product.
How the free AI video generator works
The trial is the free part: 7 days on Starter, Growth or Scale, with up to 10 posts made for you. If all you have is a link, the URL to video converter shows how a web address becomes a finished video.
Paste your website.
Postdom reads your services, prices and place, and links each fact to the page it came from.
It writes the video.
An opening line said the way people talk, then a few lines of text on screen for viewers on mute.
It edits the video.
Clips and AI-made shots matched to each line, with music, in one of 40 styles.
You approve, and it posts.
Approved videos post to TikTok, Instagram Reels, YouTube Shorts, Facebook Reels and LinkedIn at the times you set.
AI video generator
An AI video generator is software that makes a video for you from an input. The big prompt-to-video models start from a sentence you type and return a cinematic clip you then edit and post yourself. Postdom starts from your business website and returns a finished social video, written, edited and captioned.
That makes it a fit for one job in particular: a business that wants several short videos a week about what it sells, posted on schedule, without anyone filming or editing.
AI video maker
An AI video maker should leave you with a video you can post, not a project to finish. Each video Postdom makes is upright 9:16, most run 7 to 22 seconds, and each one has a hook, on-screen text, clips matched to every line, music and a caption written for the platform it goes to.
Pick the page for the kind of video you want. Each one shows real examples and works the same way: paste your website, approve, and it posts.

Text to video AI
Text to video AI turns written words into moving pictures. Most tools take a prompt or a script you type. Postdom's text is your website: it writes the script from your pages, then sets the words on screen and finds a clip that fits each line, so you never write a prompt.
The text it starts from is the same text your customers read, such as your services, prices, opening hours and answers to common questions, so every video says something true about your business.
Three kinds of AI video tool
The phrase covers three different tools. Pick by the job.
| Kind | Starts from | Good for |
|---|---|---|
| Postdom | Your business website | Short social videos for a business, made and posted every week |
| Prompt-to-video models | A written prompt | Cinematic scenes and b-roll you then edit |
| Avatar video tools | A script read by a talking avatar | Training, explainers and spokesperson videos |

Questions
What is an AI video generator?
It is software that makes video from an input such as a prompt, a script or a website. Postdom makes short social videos from your business website and posts the ones you approve to your accounts.
Is there a free AI video generator?
Yes, free for 7 days on Starter, Growth or Scale: the trial makes up to 10 posts, and an AI video can be one of them. After it, Starter is $39 a month for 30 posts. Cancel anytime.
Can it make a video from a text prompt?
No. Postdom starts from your website, not from a prompt you type, and makes short social videos about your business rather than cinematic scenes. For a scene from a prompt, a prompt-to-video model fits.
Can it make long videos?
No. Postdom makes short vertical videos, the kind TikTok, Reels and Shorts show; most run 7 to 22 seconds. For a long explainer or a training video, an avatar video tool fits better.
Do I need footage of my own?
No. Postdom builds each video from checked stock clips and AI-made shots, and you can ask for a different clip with Make changes before it posts. Videos you filmed can also be posted as they are.
Is an AI-made video labelled as AI?
Only if you want it to be. The AI label on TikTok, Instagram and YouTube is off by default; turn it on in Settings. Other platforms show no such label.
Is this like Canva or CapCut?
No. Canva and CapCut are editors with AI features, and you still build each video. Postdom generates the finished video from your website and posts it once you approve.
Can I change an AI video before it posts?
Yes: approve it, ask for a change or turn it down. Each change to a AI video uses one credit, from the credits your plan includes every month.
