Diffusely

Diffusely is a Photoshop plugin that generates images from prompts, edits with reference images, fills selections and upscales to 4K without leaving the canvas. Free accounts get three images per day plus a first-day bonus.

Diffusely is an AI plugin for Adobe Photoshop that puts image generation, prompt-based editing, generative fill and upscaling on the same canvas where artists already work. Rather than exporting a layered document to a browser tool, generating something and reimporting it, the plugin sends the request from inside Photoshop and drops the result back as a new layer. Output is matched to the dimensions of the open document, so a generated image arrives at a size that fits the artboard instead of needing to be rescaled first. The plugin bundles four workflows. Generate takes a written prompt and returns a finished image. Edit lets the user pin a reference image and describe a change, which covers background swaps, restyling objects and broader composition changes. Generative Fill works from an existing Photoshop selection and replaces only that region while the rest of the layer stays untouched. Upscale is intent-driven: pin an image, type the word upscale, and the plugin routes the request to an AI upscaler that can push resolution to 4K. The tool is aimed at digital artists, photographers and designers who already have Photoshop in their pipeline and want AI assistance without a second application or a subscription to a separate generation platform. Installation runs through the Adobe plugin marketplace, so setup is a single click, followed by a sign-in with Google or email. The plugin reports a maximum resolution of 4K and generation times under ten seconds. A free account gives three images every day with no credit card, plus a ten-image bonus on the first day, which makes it practical to test on real client work before committing. Against standalone generators, Diffusely trades breadth of models and features for location: it does not try to be a full studio, it removes the round trip. Against Photoshop's built-in generative features, it adds reference-driven editing and a fast upscale path that are not native to the host app. The trade-off is that the entire product is bound to Photoshop, so anyone working in Affinity, Procreate or a browser-only stack gets no value from it. Pricing above the free daily allowance is not published on the homepage, so current paid tiers should be confirmed directly with the vendor.
