Frequently Asked Questions about Janitor AI
Is Janitor AI free to use?
The Janitor AI platform itself is free. However, to chat with characters, you either need to provide your own API key from a supported LLM provider like OpenAI (which has its own usage costs) or use the built-in JanitorLLM option which is free but may have limitations on response quality and speed.
What is the BYOK model and how does it work?
BYOK stands for Bring Your Own Key. You create an account with an LLM provider like OpenAI, generate an API key, and enter it into Janitor AI settings. The platform then uses your API key to power conversations, and you pay the LLM provider directly based on your usage.
Can I create my own AI characters on Janitor AI?
Yes, Janitor AI provides a character creation tool where you can define your character's name, personality, backstory, greeting message, scenario context, and example dialogues. Created characters can be kept private or shared with the community.
