GenStation

GenStation is the only native iOS & macOS client that gives you both cloud models (Gemini, Grok, and 40+ models via AI/ML-API) AND direct connection to your own ComfyUI server. No subscription and no hosted models. Most AI art apps lock you into one model, one provider, and a monthly subscription. GenStation takes a different approach: bring your own API keys, connect your own servers, and keep full control over your creative workflow. ONE APP. 40+ MODELS. Connect to Gemini, Grok, and AI-ML-API to access FLUX.1, Stable Diffusion XL, SD 3.5, and dozens more. Compare results across models side by side in the session panel. Switch providers in a tap. YOUR OWN COMFYUI SERVER. Import workflows from JSON files or PNG images. Send prompts and reference images to your local ComfyUI installation over your network. Run your own custom pipelines from your phone, tablet, or Mac. 400+ ART STYLES YOU CAN STACK. Browse and combine styles like cyberpunk, film noir, watercolor, and hundreds more. Apply one or layer several to transform any generation. Create and save your own custom styles. SMARTER PROMPTS, LESS EFFORT. ▸ AI prompt enhancement turns simple ideas into detailed, model-ready prompts ▸ Video prompt builder structures camera movements, actions, and style ▸ Batch prompt generation creates dozens of themed variations at scale IMAGE MARKUP AND MULTI-IMAGE INPUT. Draw over any image to guide your next generation. Add text labels, circle areas, fill regions with color. Feed multiple reference images into models that support them to combine subjects, settings, and styles. BUILT FOR PROFESSIONALS. ▸ Full generation history with folders, search, and thumbnails ▸ Export to Photos or package images with embedded prompt metadata ▸ Edit batch prompt lists using the integrated text editor ▸ API keys stored in your device's Keychain, never shared beyond your chosen providers FREE. NO SUBSCRIPTION. NO ACCOUNT REQUIRED. GenStation does not host AI models or process your generations. You connect directly to providers and pay them on your own terms. No middleman. No markup. Requires your own API keys for Gemini, Grok, and/or AI-ML-API, or a working ComfyUI server on your local network.
