What is AIRunner?

AIRunner is an AI chat bot tool. AI Runner is a downloadable desktop app that runs Stable Diffusion image generation and a Mistral-7b chatbot on your own NVIDIA GPU, with drawing tools, outpainting, filters and prompt storage. Users bring their own models; the interface is aimed at non-technical artists but the hardware requirements are real.

AI Runner is a desktop application from Capsize Games that puts Stable Diffusion image generation and a conversational chatbot on local hardware. Rather than renting cloud GPU time or uploading prompts to a hosted service, the program runs diffusion models (Stable Diffusion 1.5, SDXL 1.0 and SDXL Turbo) and a Mistral-7b chatbot directly on the user's machine. It is a downloadable tool rather than a website, and the source notes that no technical knowledge is needed to get started, though users have to supply their own model weights. The image side is built around a canvas with collapsible panels. Prompts can be weighted, LoRAs, embeddings and textual inversion are supported, and both safetensors and ckpt files load. Drawing tools feed sketches into image-to-image conversion, outpainting extends an image to larger sizes, and filters such as the pixel art and film presets change the final look. Sessions remember settings and prompts between launches, and a prompt browser stores favourites for reuse. Metadata export and automatic image export are configurable, and an NSFW filter toggle can be switched off. The chatbot is the second pillar. Mistral-7b powers conversations with custom system instructions, bot names, personalities and moods that shift with context. Conversations can be saved and revisited, and the bot can trigger image generation or leave prompt control entirely to the user. Voice interaction is described as real-time text-to-speech and speech-to-text, with the homepage warning that this particular feature is prone to error. The realistic audience is hobbyists and artists with an NVIDIA card who already own or plan to download Stable Diffusion checkpoints and want an offline workspace instead of a browser tab. That framing matters, because AI Runner competes with polished cloud generators but wins on privacy and no per image billing, at the cost of hardware setup and a Linux first system profile. It suits people who enjoy tuning memory options like attention slicing and CPU offload more than they mind missing hosted conveniences.

How do you use AIRunner?

  1. 1Download AI Runner from its itch.io page
    Open the tool page on itch.io and download the build for your machine. The listing describes the app as a downloadable tool with an easy setup and installation flow.
  2. 2Install and launch the application
    Run the installer, then open the app. Setup requires an active internet connection the first time because models have to be fetched afterwards.
  3. 3Download Stable Diffusion models
    The built-in model downloader pulls the checkpoints you need, or point the app at a folder you already use. Both safetensors and ckpt formats are accepted.
  4. 4Generate and edit on the canvas
    Write a prompt, adjust weighting, add LoRAs or embeddings, then generate. Use the drawing tools and image-to-image for sketches, outpaint to extend the frame, and apply filters afterwards.
  5. 5Set up a chatbot
    Open the chatbot panel and give the bot a name, system instructions and personality. Conversations are saved, and the bot can generate images or hand prompt control back to you.
  6. 6Track releases and fixes
    The devlog carries release notes, patch announcements and Docker instructions. Check it before upgrading, since builds are updated frequently and downloads have been paused before.

Pros and cons

Pros

  • Runs image generation and chat locally, so prompts and outputs stay on the user's machineAI
  • Supports Stable Diffusion 1.5, SDXL 1.0 and SDXL Turbo with LoRAs, embeddings, prompting weights and both safetensors and ckpt filesAI
  • Canvas with collapsible panels, outpainting, drawing tools and a sketch to image workflow in one editorAI
  • Chatbot accepts custom names, personalities and system instructions, saves past conversations and can trigger imagesAI
  • Prompt browser, stored sessions, metadata export and memory tuning options give fine control over repeat workAI

Cons

  • No bundled models: users must find and download Stable Diffusion checkpoints before any art can be madeAI
  • Real-time voice conversation with the chatbot is flagged on the site as prone to errorAI
  • CPU generation is limited and the developer advises against running without a CUDA capable GPUAI
  • Stated system requirements start at an RTX 3060 with 16 GB RAM and 36 GB free storage, and recommended specs list Ubuntu, so Windows and Mac users get no documented pathAI
  • The listing carries no pricing information and no support channel beyond the itch.io page, leaving buyers to judge value from devlogsAI
