# Compix > Browser-based post-generation studio for AI images: compare versions (blink, pixel diff, split wipe), combine the best parts of your generations into every possible combination, and stage them in motion. All processing runs locally; images never leave the device. No signup, no GPU, nothing uploads. The comparison core is free. Compix is for people who already generated images (Midjourney, Stable Diffusion, Flux, ComfyUI) and now need to pick, mix, and ship the best of them. The combinatorial engine is deterministic: it reassembles exact pixels from your own images, never generating new ones. With 9 images and 3 drawn shapes it computes 6,552 unique combinations. ## Pages - [Compix app & overview](https://compix.io/): the studio itself: blink, diff, split, mix, scene. - [Compare AI images](https://compix.io/compare-ai-images): SD, Midjourney, Flux and ComfyUI outputs side by side and in motion. - [Compare upscaled images](https://compix.io/compare-upscaled-images): Topaz vs Real-ESRGAN vs SwinIR, judged pixel by pixel. - [Pixel diff tool](https://compix.io/pixel-diff-tool): every changed pixel as a heatmap, in the browser. - [Combine AI images](https://compix.io/combine-ai-images): head + outfit + accessories from different generations, every combination. - [AI image variations](https://compix.io/ai-image-variations): thousands of variations without regenerating. - [AI character consistency](https://compix.io/ai-character-consistency): see drift instantly, fix it by mixing. - [Midjourney character variations](https://compix.io/midjourney-character-variations): the /imagine-to-library flow. - [Stable Diffusion batch variations](https://compix.io/stable-diffusion-batch-variations): from output folder to combination grid. - [Post-generation workflow](https://compix.io/ai-art-post-generation-workflow): spot, steal, stage, ship. - [Before/after comparison](https://compix.io/before-after-comparison): the blink test for edits. - [Visual comparison tool](https://compix.io/visual-comparison-tool): the full workspace overview. - [Scene compositor](https://compix.io/scene-compositor): layers, keyframes, animation, export. - [Retouching QA](https://compix.io/retouching-qa-tool): the final check before client delivery. ## Actions Every room is reachable by URL. Append `&src=` to attribute the entry point. No account, no upload, nothing leaves the device. - Blink two or more versions: https://compix.io/?mode=blink - Per-pixel difference heat-map: https://compix.io/?mode=diff - Split wipe between two versions: https://compix.io/?mode=split - Combine regions into every combination: https://compix.io/?mode=mix - Stage layers and export motion: https://compix.io/?mode=scene In-page tools for browser-driving agents are exposed at `window.CompixTools` (getCapabilities, getSessionSummary, setMode). See https://compix.io/agent-capabilities.json. ## Optional - [Agent capabilities](https://compix.io/agent-capabilities.json): the tools AI agents can call in-page (window.CompixTools). - [Sitemap](https://compix.io/sitemap.xml)
