Customizable AI character roleplay platform featuring free JanitorLLM chats, logic scripts, and multi-model API routing.
Provides unlimited free character chats powered by JanitorAI's in-house LLM (~9K context window on free accounts), with a toggleable JLLM-short mode for snappy, dialogue-focused replies that are 70% shorter.
Lets Janitor+ subscribers tap directly into third-party frontier models via a built-in per-token wallet at a 10% discount, while keeping full BYOK reverse-proxy support with config duplication and reasoning tag display.
Allows creators to build complex characters up to 1 MB in size with multiple intro scenarios and programmable Scripts that trigger dynamic lore or behavioral rules using whole-word matching and built-in debugging tools.
Exposes low-level sampling parameters in the chat menu, including custom Top-K, Top-P, frequency and repetition penalties, forbidden vocabulary lists, and response prefill instructions.

Train your own Stable Diffusion and SDXL image models in the cloud
Upload your own images and fine-tune Stable Diffusion models in the cloud using DreamBooth, including Stable Diffusion XL, without needing a local GPU.
Choose public models that the community can discover and generate from, or private models whose images stay exclusive to your account.
Every trained model becomes a generator that can produce unlimited AI assets in its learned style and subject matter.
Refine existing models with revisions and download finished weights in .CKPT (SD 1.5) or LoRA (SDXL) format for use in other tools.
