AGPL-3.0

What it does

One interface across many providers — local backends, OpenAI, Claude, Mistral, OpenRouter and more — with character definitions, lorebooks, Visual Novel mode, image generation and TTS hookups, auto-translate, and more prompt controls than most people will ever touch. Mobile-friendly, documented in several languages including Japanese. The depth is the barrier: if you just want answers to questions, something simpler will serve you better. AGPL-3.0.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

SillyTavern FAQ

Is SillyTavern free?: SillyTavern itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
Do I need to install anything or write code to use SillyTavern?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does SillyTavern work on a phone?: No. It needs a computer.
Can I use SillyTavern commercially?: The licence is AGPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
