ProductFlow turns a product photo and a few facts into finished selling material, giving solo merchants and small teams one workspace for copy, posters, and repeatable image generation. You start by creating a product record, attaching original and reference images, then arranging product data, copy nodes, and image nodes on a zoomable canvas with drag, pan, multi-select, and connections. Copy nodes generate editable structured text that you can review, confirm, and keep in history before downstream image nodes read it. Poster generation runs in template mode with local rendering or generated mode through an image provider, and completed results can be downloaded, saved as product references, or promoted to the main product image slot. A separate image session view supports text-to-image and image-to-image runs with base image selection, candidate comparison, queue position, progress, cancel, and retry. Every finished image can move into the gallery with its source session, linked product, prompt, size, and model recorded for later reuse. Runtime settings cover provider profiles, model bindings, image tool parameters, prompt templates, upload limits, and concurrency, guarded by a separate settings token. The built-in help pages document the canvas, gallery, image sessions, and configuration in searchable sections.
