Wan 3.0 Prompt Generator
One line in, Alibaba's own structure out

Type the idea in one line. This Wan 3.0 prompt generator writes it out in the structure Alibaba published — entity, scene, motion, camera, style — with the beats spaced to the length you picked. Free, no account, and no cap on how many you write.

Checks12 rules, run before you copy

Composed in Alibaba's published order
Exclusions written as sentences, not a negative prompt
Camera move named with neither amplitude nor speedthe camera pushes in

The grey skeleton is the order we compose in — three sections, four with references. Wan 3.0 reads one plain paragraph, so the labels are never written into it.

0 / 20,000 characters

Generating needs an account, and the first clip on it is free: 480P, up to three seconds, with sound.

The promise

Free, and actually free

Every other Wan 3.0 prompt tool we checked in August 2026 says "free" and means something narrower than the word does — one prompt per session, or three a day, then an account. This one has no counter. Write forty prompts this afternoon if that is what the shot needs.

The reason is arithmetic rather than generosity. Writing a prompt costs us a fraction of a cent in language-model time. Generating the video costs real money — that is the part we charge for, and we say so on the pricing page instead of hiding it behind a free trial that runs out mid-project.

Free here, with no cap

Writing and rewriting Wan 3.0 prompts, as many as you like
Checking a prompt somebody else wrote
The prompt library — worked prompts beside the clips they made

Costs credits

Generating the video — your first clip is on us: 480P, up to three seconds, with sound
720P and 1080P, and anything longer than three seconds
Reference video, which bills at the same rate as the output

No email, no card, and no "sign up to continue" after the third one. If you never generate a video here, the prompt tools still work.

Four input shapes

One prompt generator, four Wan 3.0 input shapes

What you attach decides how the prompt has to be written, so it comes first. Wan 3.0 publishes no mode codes — what changes is the type on each attachment, which is what the badge on each card names.

Text
no media
The whole timeline is built from words.
Ratio required — adaptive is refused
First frame
first_frame
Your picture opens the shot and the clip develops forwards.
First + last
first_frame + last_frame
Two pictures, and the path between them is generated.
References
reference_image / _video / _audio
Assets define subjects; the scene is built to obey them.

The two frame shapes add a line text prompts do not have: an alignment statement pinning each picture to its moment. They also ignore your ratio — the picture decides. And they cannot be combined with references: Wan 3.0 rejects a request carrying both rather than picking one.
This page writes the words. The attaching happens on image to video and reference to video, and the prompt travels there with the button in the result panel.

Reference mode: one extra section, and citations that bind

Reference mode adds one section that says what each attachment is. Wan 3.0 has no retention vocabulary and no separate summary — an attachment is cited inline as Image 1, Video 1 or Audio 1, and described once. The numbering is per type and in upload order, and it is case-sensitive: image 1 does not bind to anything. Cite one you did not upload and the model has nothing to point at. More on the two families that cannot be mixed: reference to video.

The format

The formula Alibaba published

Alibaba's own documentation gives the order a Wan 3.0 prompt should follow. Most tools ignore it and write pretty sentences instead. This one follows it, because the order is part of the instruction — and none of it is written into the prompt as a label, since Wan 3.0 reads one plain paragraph.

EntityThe subject, described concretely enough to picture.
SceneWhere it is, what time of day, what is behind it.
MotionWhat moves, how far, how fast — stillness counts.
Aesthetic controlShot size, camera move, lens, light.
StylizationA named look, only when the shot needs one.
SoundWritten alongside the picture, not after it.

Why the order is the instruction

The five layers go from what is in frame to how it is shot, which is the sequence a crew would work in. A prompt that opens on the lens and reaches the subject last gives the model its most specific constraint first and its most important one last. The generator composes in this order every time, so what you edit afterwards is the wording rather than the shape.

Entity → Scene → Motion → Aesthetic control → Stylization

Sound is the sixth thing, and it is not optional

Wan 3.0 generates the audio in the same pass as the picture, so the prompt is also the sound brief. Say nothing about it and you still get a soundtrack — one the model chose. The split we compose to is what the scene itself makes against what only the audience hears, because that is the line a viewer can hear.

Rain on fabric and asphalt — and, for the audience only, sparse lo-fi jazz held under it.

Camera grammar

Name the camera move, get the feeling

"Cinematic" is not a camera instruction. Alibaba's prompt guide pairs each move with the feeling it produces, and this generator writes the wording rather than the adjective.

Motionpush in
Amplitudea small move
Speedslowly

Push inIntimacy, or rising tension — the most reliable Wan 3.0 move.
Pull outScale, or isolation.
Tracking shotPlaces you alongside the subject.
Arc shotSays this subject is the important one.
Static shotStillness and focus.
cinematic camera workNothing in it to execute.

"The camera pushes in slowly, a small move" is executable. "Cinematic camera work" is not, and it costs characters to say. Leave amplitude and speed out when you mean medium and normal — the checker only flags a move that gives neither.

Say static when you want a locked frame: a camera you never mention is a camera the model is free to move.

The rules

Four Wan 3.0 rules this generator handles for you

These four trip up anyone writing Wan 3.0 prompts by hand, and none of them is guessable. The generator applies all four automatically, and the checker looks for them in anything you paste.

There is no negative prompt fieldso exclusions go in as sentences — “no music”, “no on-screen text”
Dialogue needs braces{ } is the whole mechanism — outside them a line is narrated, not performed
Reference numbering is case-sensitiveImage 1 binds; image 1 and Image_1 bind to nothing
Length changes the structureone action under 8s; ordered beats past 15s, ending named

One finding, as the checker writes it

"the camera pushes in" — gives neither amplitude nor speed.

Try: the camera pushes in slowly, a small move.

Twelve checks run before you copy, these four among them. The rest cover the things that fail quietly: a prompt past the twenty-thousand-character ceiling, which Wan 3.0 truncates instead of refusing; a section label left in the text, which it renders as words on screen; a prompt written in another model's format, which it reads as prose.

Paste anything into the Check tab and it gets the same treatment, with the failing line quoted and a fix suggested. Finding a broken prompt normally costs a paid generation. Here it costs nothing.

Length is structure

The same idea, written three ways

One input — "a courier in the rain" — at three Wan 3.0 lengths. Read them side by side and the pattern becomes obvious: the length does not add adjectives, it adds structure.

3 seconds
a courier in the rainOne subject, one action, one framing — no beats, because there is no room for a change
10 seconds
a courier in the rainThe action, one camera move across the whole clip, and a sound bed named
25 seconds
a courier in the rainThree ordered beats with the transitions stated, the camera changing once per beat, and an ending specified rather than invented

The last one is the reason the length picker sits next to the idea box rather than in an options panel. An unplanned final third is the most common way a long Wan 3.0 clip goes wrong, so past fifteen seconds the generator names the closing beat whether you asked for one or not.

A worked example

What the generator actually changes

Structure is easier to see than to describe. This is the example behind the Rain alley button above — one line in, and what came back.

a womanGiven an age, a haircut and a coat. A person you could cast beats a noun.
rain-soaked, at nightGiven a light source: a flickering red ramen sign, neon on wet asphalt. Rain is weather; the shot needs something to see by.
then smilesGiven its own beat and its own framing — a tight close-up, camera static. Ten seconds holds two shots, and the cut has to be stated.
(nothing about sound)Rain on fabric and asphalt, drips off the awning, a food cart sizzling to the left. Wan 3.0 generates audio in the same pass, so silence is a decision you make by accident.
(nothing about music)Sparse lo-fi jazz entering halfway and held under the rain. The score is the one layer the characters cannot hear.

One line in

Plain words, no structure, no camera. This is the whole input.

A woman waits under a dripping awning in a rain-soaked Tokyo alley at night, then smiles.

What came back

One paragraph, in the published order, with no labels anywhere in it. Two more paragraphs follow it for the sound and the score, and all three are yours to edit before you copy.

Live-action, cinematic, a medium-wide shot frames a rain-soaked Tokyo alley at night, lit by a flickering red ramen sign and wet neon reflections on the asphalt. A woman in her early 30s, short black bob, oversized grey trench coat, stands under a dripping awning holding a paper umbrella. The camera pushes in slowly, a small move as she watches steam rise from a food cart to her left. Then, a tight close-up on her face. The camera holds a static shot. Raindrops streak the frame edge. She exhales, breath visible, and a faint smile forms as she looks off-camera right.

Take it straight to the generator

Most prompt tools hand you text and wish you luck, which leaves you on somebody else's site finding out whether the prompt was any good. The button in the result panel drops it into a real Wan 3.0 generator here, with the length and the aspect ratio already matching what you wrote it for.

01
Write it, edit it, check it
Every section in the result panel is editable, and the checks re-run as you type.
02
Press the button in the panel
The prompt, the length and the ratio travel together, so nothing gets re-typed — and the mode decides where it lands.
03
Generate
This part needs an account, and the first clip on it is free: Wan 3.0 itself at 480P, up to three seconds, with sound.

Open text to video

Or copy it and paste it anywhere else — the prompt is yours, it is plain text, and there is nothing to unlock.

Questions people actually ask

Wan 3.0 prompt generator questions

Nine answers · all visible · nothing collapsed

Is the Wan 3.0 prompt generator really free?

Yes, with no account and no daily cap. Writing text is cheap; generating video is not, and video is where we charge. The section above lists exactly which tools are free and which are not.

Do I need an account to use the Wan 3.0 prompt generator?

No. Nothing here is gated. There is a rate limit to stop automated abuse, but ordinary use never reaches it — and if you do, it asks you to slow down rather than telling you that you are out.

How long should my Wan 3.0 prompt be?

Wan 3.0 accepts twenty thousand characters, and most good prompts use two hundred. Length is not the goal — a prompt where every sentence has a job beats a long one that repeats itself. Past the ceiling Wan truncates silently rather than refusing, which is why the counter warns before the wall.

Can I write Wan 3.0 prompts in Chinese?

Yes. Wan 3.0 reads both, and Alibaba's own documentation examples are in Chinese. This generator writes English by default, and the checker only asks that one prompt picks one language for its description — spoken lines in braces can be in whatever the character speaks.

How do I write dialogue?

Put the exact words in braces. Braces are the entire mechanism Wan 3.0 uses to tell a spoken line from a narrated one, so who says it and how they say it stay outside them, in the prose. A paraphrase — "she says something reassuring" — gets you a line the model invented.

Why does the generator not add a negative prompt?

Because Wan 3.0 has no negative prompt field. Anything you write as one reaches the model as words to render, which is how a clip ends up with "blurry, low quality" on screen. Exclusions belong inside the prompt as instructions, and the generator writes them that way.

I pasted a prompt from another tool and it failed every check. Why?

Most likely it was written for a different model. Shot markers, timestamps and angle-bracket asset tags are somebody else's format; Wan 3.0 reads plain prose and renders the markup as text. The checker names the format rather than reporting the pieces one by one.

Will the prompt work on other video models?

Partly. The subject, scene and camera language transfer to most models. The Wan 3.0 specifics — braced dialogue, the reference numbering, the thirty-second beat structure — are ours and may confuse other systems.

What if I already have a video I want to copy?

Use video to prompt instead. It works backwards from a clip to a Wan 3.0 prompt, it is free too, and you can bring the result back here to edit. If you want prompts that already worked, the prompt library has them beside the clips they produced.

Write a better prompt in ten seconds.

One line in, a structured Wan 3.0 prompt out. No account, no counter, and a button at the end that actually generates the thing.
