Build a better prompt for your AI video.

Pick your subject, action, camera move, lighting and style. This builder assembles them into a polished prompt you paste into Sora, Runway, Pika, Kling, Veo or Luma.

This tool writes prompts — it does not generate videos. Everything runs in your browser; nothing you type leaves your device.

Notes for popular generators

Every AI video tool reads prompts a little differently. These are general tendencies, not official rules — when in doubt, try the same prompt in two tools and compare.

Questions about AI video prompts

Does this tool generate videos?

No. This is a prompt builder: it helps you write better text prompts, which you then paste into an actual AI video generator such as Sora, Runway, Pika, Kling, Veo or Luma. Nothing here renders a single frame of video.

What makes a good AI video prompt?

Five building blocks: a specific subject, one clear action, a defined setting, a camera instruction, and a look (lighting plus style plus mood). Vague prompts ("a cool video of a city") give the generator too many decisions; specific ones ("a drone flyover of a neon-lit harbor at night, cinematic, tense") give it direction. This builder assembles all five for you.

Which AI video generator should I use?

It depends on what you need: Sora, Runway, Veo, Kling, Pika and Luma are all popular text-to-video options, and most offer free tiers or trials. For a first project, pick one with a free tier, run the same prompt in two of them, and compare — the differences in motion quality and style adherence are immediately visible.

How long should my prompt be?

One to three sentences is a good starting point for most generators. Some tools prefer short prompts with a single action (Pika is the classic example), while others reward longer, more detailed descriptions (Sora tends to). Start medium, then lengthen or shorten based on what your chosen tool returns.

What is a negative prompt?

A negative prompt tells the generator what to avoid: common entries are "blurry", "watermark", "extra limbs" and "distorted faces". Not every generator supports negative prompts, but the ones that do treat them as hard constraints, so they're worth filling in when the option exists.

Do my prompts leave my device?

No. Everything you type stays in your browser — the prompt is assembled locally with JavaScript and never sent anywhere. Only copy it out when you're ready to paste it into a video generator.

How the AI video prompt generator works

An AI video generator is only as good as the prompt you feed it. This AI video prompt generator turns a few choices — subject, action, setting, camera movement, shot type, lighting, visual style and mood — into a structured, ready-to-paste prompt for tools like Sora, Runway, Pika, Kling, Veo and Luma. The prompt assembles live as you type: a style and shot-type opener, a subject-action-setting sentence, camera and lighting lines, and your aspect ratio and duration hint. Fill in the negative prompt field to exclude things like watermarks, blur or distorted faces. Everything runs in your browser, so nothing you write ever leaves your device. For more hands-on inspiration, the eight one-click presets cover the most common recipes — cinematic chase, product shot, anime scene, drone landscape, talking head, music video, sci-fi corridor and cooking close-up — and each one loads the whole builder so you can reshape it into your own idea.

What you can do with the results

Copy the assembled prompt into whichever generator you use and run it. If the render misses, iterate on one variable at a time — change the camera move first, then the lighting, then the style — rather than rewriting everything, so you learn what each control actually does on that tool. The per-generator notes above give you honest starting points: Pika generally prefers short prompts with a single action, Sora tends to reward detailed descriptions of motion and physics, and Runway behaves well with subject and camera stated up front. Pair this with the image compressor if you need to shrink thumbnails or stills for the same project, and browse all free tools for the full collection.
