1. Architectural Philosophy
| Dimension | Janitor AI (All-in-One Cloud) | SillyTavern (Decoupled Self-Hosted) |
|---|---|---|
| System Architecture | Integrated Web UI, community hub, and free cloud model. | Standalone local frontend connecting to external or local model backends. |
| Hosting & Storage | Cloud database managed by Janitor AI. | 100% local on your PC; zero data leaves your disk when running local models. |
| Hardware Demand | Runs on any browser, smartphone, or tablet. | Requires modern PC/GPU if running local open-weights LLMs. |
Janitor AI is designed for friction-free access: log in, pick a bot from the trending feed, and start typing.
SillyTavern is the ultimate power-user’s Swiss Army Knife. It is not an AI service itself, but rather an extraordinarily advanced user interface that runs locally on your computer or phone, connecting to whatever AI backend you provide.
