Fulla

Generative fill in Photoshop. Pay only for the images you make.

Fulla is a free Photoshop plugin. Select an area, say what you want, click Generate: just like Photoshop's own generative fill, with your own account at an AI service (OpenRouter, Google or OpenAI). From about 5 cents an image, no subscription, no credits.

Why Fulla

• Pay for what you make. You pay the AI service per image; Fulla shows the cost in dollars after every run.
• Sharp enough for print. Up to 4K, chosen from the size of your selection.
• Blends into your photo. The whole photo goes along for context, and the colours of the result are matched to it.
• Reference images. Show the model the real pattern, face or object.
• No server. Fulla talks to the AI service you chose, directly. Your keys stay on your computer.
• Free and open source, MIT.

Models: Nano Banana 2.1 (recommended), Nano Banana Pro, GPT Image, Qwen Image, through OpenRouter (one account for all, a few clicks from the panel) or your own Google or OpenAI key. See Models.

Install

You need Photoshop 2026 (27.11 or later).

With the Creative Cloud app (Windows and macOS): download fulla-<version>.ccx from Releases and double-click it. Creative Cloud warns that the plugin comes from a third-party developer; the first time, Windows may ask for administrator rights.

Without the Creative Cloud app or administrator rights (Windows): download fulla-<version>-windows.zip, unzip it, close Photoshop and double-click Install Fulla.bat. Uninstall Fulla.bat removes it again.

• Copies the plugin to %APPDATA%\Adobe\UXP\Plugins\External\io.github.toorop.fulla.
• Adds one entry to Photoshop's plugin list, %APPDATA%\Adobe\UXP\PluginsInfo\v1\PS.json, after saving a backup copy next to it. Other plugins are left untouched.
• Uninstall Fulla.bat removes both again.

Then open Plugins > Fulla and click Connect with OpenRouter, or add a Google or OpenAI key. The guide takes you from there: First run, Your first fill, Troubleshooting.

Limits

More in Limits on the website.

• The providers return at most about 4K pixels. Filling most of a large photo means upscaling, which looks softer; the panel tells you when that happens.
• The providers treat the mask as a guide, not a hard edge. Fulla clips their result to your selection.
• Cancel stops Fulla from using a result, but the provider may still bill the request it already received.
• Colours are right only when Photoshop keeps embedded profiles (see Colours). A result that comes back as WebP gets no profile yet (PNG and JPEG do).
• The Windows installer is Windows only; on macOS use the .ccx.

Develop

npm test          # unit tests, no dependencies
npm run package   # builds dist/fulla-<version>.ccx and -windows.zip

Load plugin/manifest.json in Adobe's UXP Developer Tools (turn on Watch to reload on every save), or install a dev copy with installer/install.ps1 -Source plugin; not both, they share the plugin id. UXP Developer Tools needs Photoshop's developer mode on (Preferences > Plugins > Enable Developer Mode), otherwise Load fails with "Failed to load the devtools plugin". To add a provider, write one file in plugin/src/providers/ with the same shape as openai.js and list it in providers/index.js.

Release

1. Set the same version in package.json and plugin/manifest.json.
2. Add a ## X.Y.Z section, written for users, at the top of the website's Changelog page (site/src/content/docs/docs/changelog.md). It becomes the release notes; links such as /docs/... are turned into links to the website.
3. Commit and push, then push the tag:

   git tag vX.Y.Z && git push origin vX.Y.Z
   

4. .github/workflows/release.yml runs the whole CI, checks that the tag matches both versions and that the Changelog section exists, builds the .ccx and the Windows zip, adds SHA256SUMS.txt, and creates a draft release. Nothing is public yet.
5. On GitHub, read the draft, tick Set as a pre-release if wanted, and click Publish release.

If a step fails, no release is created. Fix the cause, move the tag (git tag -d vX.Y.Z && git push origin :refs/tags/vX.Y.Z, then step 3 again), or re-run the workflow if nothing needed fixing in the repository.

Dev installs only; release packages leave it out. With the Fulla panel open, write {} to selftest.json in the plugin's data folder:

%APPDATA%\Adobe\UXP\PluginsStorage\<host>\<version>\<kind>\io.github.toorop.fulla\PluginData
