ArtBot Ai
ArtBot is a free web client for generating images through Stable Diffusion on the AI Horde distributed GPU cluster. You open the create page, write a prompt, pick a model and sampler, and send the job to community workers without installing software or creating an account.
The interface covers text-to-image, image-to-image, inpainting, ControlNet, live paint, and a drawing canvas. You can tune steps, guidance, CLIP skip, seed, LoRAs, textual inversions, upscalers, and post-processors like GFPGAN or CodeFormer. Generated images stay in your browser via IndexedDB, with galleries for pending and completed work.
ArtBot is maintained by Dave Schumaker as an unofficial front end to AI Horde. The project is open source on GitHub, and the site reports more than 30 million images generated through the app.

Is ArtBot free to use?
Yes. ArtBot is free and does not require an account. Image jobs run on the AI Horde cluster, which uses a kudos priority system rather than paid subscriptions.
Do I need to log in to use ArtBot?
No. You can generate images anonymously. Logging in with an AI Horde API key gives higher queue priority and access to some advanced limits.
What is the AI Horde and how does ArtBot connect to it?
AI Horde is an open source distributed cluster that runs Stable Diffusion jobs on volunteer GPU workers. ArtBot is an unofficial web front end that sends your prompts to that cluster and stores results in your browser.
What are kudos on ArtBot?
Kudos are AI Horde priority points, not a currency you can buy. You earn them by contributing GPU power, rating images, or participating in the community, and they affect queue speed.
Does ArtBot have a mobile app?
No dedicated mobile app is listed. ArtBot runs in the browser and supports PWA-style installation, though some features work best on desktop.
