What VideoByPrompt is
VideoByPrompt is a free AI video generator. You type one sentence — a scene, a product, a story, a joke — and our engine turns it into a real video clip, with motion, lighting, and sound. There is no account to create, no email to verify, no credit card, and no credit system. You open the site, you type, you generate, you download. That is the whole product.
Every video is generated with Seedance 2.5, a modern text-to-video model known for smooth motion, realistic physics, and native synchronized audio — including spoken dialogue and lip-sync. You can generate from text alone, or start from an image and animate it. Clips can be up to 30 seconds long, in 16:9, 9:16, 1:1, or 21:9, at up to 1080p.
Alongside the video generator, the site includes two companion tools: a free AI image generator for turning text into still images, and a free AI video prompt generator that helps you write stronger prompts when you are stuck for words. Our guides explain how to get the best out of all three.
Our mission: free creativity for everyone
Most AI video tools hide behind paywalls: a few free credits, then a subscription. We think that is the wrong shape for creativity. A student making a class project, a small shop filming its first product ad, a creator testing an idea at midnight — none of them should have to reach for a wallet before they can see whether an idea works.
So VideoByPrompt is free, without limits on how many videos you can make, without credits that run out, and without a sign-up wall. A fair-use daily limit keeps the service available for everyone, but there is no paid tier waiting behind it. If the site ever asks you to pay, it is not us.
How it works
Write what you want to see — a place, a subject, an action, a mood. Add dialogue in quotes if you want someone to speak.
Choose the shape (16:9 for YouTube, 9:16 for Reels and TikTok), the length, a camera motion, and a style. Or just press generate.
Seedance 2.5 renders your clip in about a minute. Watch it, download the MP4, and use it wherever you like.
Who it is for
VideoByPrompt is built for creators of every kind: YouTubers and TikTokers making Shorts and Reels, marketers producing product ads, teachers illustrating a lesson, small businesses showing off a product, and anyone who has ever thought "I wish I could show this as a video." You do not need editing skills, a camera, or a budget — just an idea and a sentence.
What we believe
- Free means free. No trials that expire, no watermarks held hostage, no "pro" lock on the good settings.
- Simple beats powerful. One sentence should be enough to make a video. Controls are there when you want them, invisible when you do not.
- Honest about AI. AI video is remarkable and imperfect. We say what the tool can and cannot do, and we expect you to label AI content where the platform you publish on asks for it.
- Privacy by default. No account means nothing to leak. Your history lives in your own browser, and you can clear it any time. Read the full Privacy Policy.
