Build the workflow once. Then run it for every brief after.

Turn one product photo into a whole ad campaign. A Mac and Windows app with 174 AI models. Bring your own key, pay the AI company directly, nothing expires.

How it works

1. Open a template or ask Copilot.
2. Wire prompts and references into models.
3. Run one node or all of them. The cost shows first.
4. Keep what works, branch what almost does.
5. New brief, new photo, rerun.

What is in it

• Brand Kit: paste a URL and get the colours, fonts, logos and business details, each labelled with where it came from.
• Tagging: @ sends a Brand Kit photo or colour into a prompt, $ sends another node’s output.
• Copilot agrees the direction with you, then builds the graph.
• Flowgen is an MCP server, so Claude, Codex, Cursor and other agents can drive the canvas.
• Workflows and media sit in a local database. Keys are encrypted. Nothing leaves but the prompt.

Questions people ask before buying

What is a workflow?

The boxes and arrows you build on screen. One box holds your photo, one holds what you typed, and the arrows feed them into an AI model. Save it and the whole thing is reusable next month.

What is a template?

A workflow somebody already built for you. Open it, put your own photo and words in, press Run. Four come with the app, and you can save your own.

What is Copilot?

A chat window inside the app. Tell it what you want in a sentence. It writes back a plan, you change whatever you disagree with, and it builds the workflow for you. It runs on your ChatGPT or Claude plan.

What counts as a run?

One image or one video. Chat with Copilot is free, and so is anything that does not generate.

Do I need my own API key?

Yes, or a paid ChatGPT plan. Flowgen does not sell image or video generation. You open an account with fal, Google, Higgsfield or Kinovi, paste the key in once, and they bill you for what you make. We never touch that money.

What do I need to start?

A Mac on macOS 11 or newer, or a PC on Windows 10 or newer. Plus one key from fal, Google, Higgsfield or Kinovi, or a paid ChatGPT plan. One is enough.

How much does an image cost?

Between about half a cent and twenty cents, depending on which AI model you pick. The exact price is on the Run button before you press it, and the prices page lists every model.

How is this different from Higgsfield, Weave or FLORA?

They charge you every month for credits, and whatever you do not use disappears. Your files live on their website. Flowgen is an app you buy once. You pay the AI companies directly, nothing expires, and your files are on your own computer.

Which provider is cheapest?

It depends on the model. Nano Banana Pro is $0.067 on Kinovi and $0.15 on fal, for the same picture. The prices page compares all of them, updated daily.

Is the Mac app safe to install?

Yes. Apple has checked and signed it since version 0.1.0-beta.5, so it opens like any other app, with no warning.

Is there a Windows build?

Yes, for Windows 10 and 11. It is not signed yet, so Windows shows a blue "protected your PC" box on first run. Click More info, then Run anyway.

Does the licence include image credits?

No. The $25 buys the app. Images and videos are billed by whichever AI company you connected, at their own price. We add nothing.

Can I use my ChatGPT plan?

Yes. Sign in with Codex. Making images needs a paid plan.

Can I use my Claude plan?

For Copilot, yes: sign in to Claude Code and pick Claude plan. Images need a different connection, because Anthropic does not make an image model.

Where are my files?

On your own computer: ~/Library/Application Support/Flowgen on a Mac, %APPDATA%\Flowgen on Windows.

Does anything leave my computer?

Only the words you typed, sent to the AI company you picked, plus anonymous crash reports. Your images and your workflows stay put.

What happens after two years?

Nothing breaks. You keep every version you already got, forever. Only versions released after that need a renewal.

Does it work offline?

You can build and edit offline. Making an image needs the internet.

Is Linux coming?

Not yet. Vote for it on the roadmap and it moves up.

Can I get it free?

The first 100 testers can. Build one workflow, email [email protected] telling me what broke, and the licence is yours.

Can it write a story for me?

Story mode, which turns a written scene into shots, is being built. Everything else on this page is in the app today.

Can I sell what I make?

Flowgen puts no limit on it. Whatever licence the AI model you used has still applies.
