Fluxion, by Synthemo.

Describe it. See it.

Type a prompt, pick a model like FLUX 3, Seedream or Nano Banana, and generate. Turn a premise into a cast and a storyboard with Story. When you want more control, switch to Node mode and wire prompts, models, masks and video into pipelines you can rerun.

Free plan with daily credits. Pro from $12 a month.

Where everyone starts. One prompt, one click.

How it works

Start simple. Go deeper when you want.

Simple mode

For everyone, and where you start.

One panel, no wiring. It's the default on desktop and the whole app on your phone. A Story tab sits beside it when you want to tell one.

  1. 1Describe itType what you want to see, or start from a style preset like Cinematic or Watercolor.
  2. 2Pick a modelFLUX 3, Seedream, GPT Image, Nano Banana and more. The credit cost shows before you generate.
  3. 3GenerateSketch four quick drafts first if you like. The result saves to your library.
Node mode · advanced

When you want control, wire it up.

Flip the switch to Node and every step becomes a node on a canvas. Connect a prompt to a model, a model to a mask, a mask to an inpaint. Tweak one node and rerun only what changed.

Story · new

From one line to a storyboard.

Give Story a premise and it writes the rest: who's in it, where it happens, how it looks, and every shot. Then render it frame by frame with the same faces and places throughout. It's a tab in Simple mode and a node in Node mode.

  1. 1
    PremiseOne line is enough. Pick how many shots, and a style if you have one in mind.
  2. 2
    Story scriptA title, a look, a cast, its places and a numbered shot list, all editable. Rewrite any shot, or the whole cast.
  3. 3
    Cast and placesA portrait for each character, or cast a real person from a photo; a set plate for each place. Every frame draws them the same.
  4. 4
    StoryboardRender it shot by shot with any model, then refine the keepers with a stronger one. Edit any frame’s prompt, redo, reorder, export a PDF.
  5. 5
    AnimateTurn each frame into a clip with Seedance, Kling, Veo, LTX and more, then play the story through and export it as one video.

Clips in, a finished video out.

Cut your clips together without leaving Fluxion: trim them, put them in order, join them with crossfades, and score the whole thing with AI music. It's a tab in Simple mode and a node in Node mode.

  1. 1
    Pick your clipsSelect videos in your gallery and choose Add to edit, or drag them in. Story clips, Video Diffusion runs and your own uploads all work.
  2. 2
    Trim and orderDrag the handles to cut each clip down, reorder them, and use a clip twice. The file is never cut, so you can always change your mind.
  3. 3
    Transitions and fadesA cut, a crossfade or a dip to black between any two clips, and a fade in and out for the whole video. Mute any clip’s own sound.
  4. 4
    AI musicDescribe the mood and make a track with ElevenLabs Music, sized to your edit, or upload your own. Keep every take, and use up to three tracks that crossfade from one to the next. About 3,740 credits for 30 seconds.
  5. 5
    ExportOne mp4 at 720p or 1080p in any shape, or just the soundtrack as audio, free. It lands in your gallery, and My edits keeps every cut to come back to.
The Orchard Keeps TimeTwo musicians, an orchard at dusk, one song. Written with Story, cut and scored in Edit.
