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.

Immersive AI simulation practice for workplace skills
Employees practice realistic, high-pressure scenarios with interactive avatars that respond in character, so rehearsal happens without involving peers or managers.
Self-directed simulation practice is paired with personalized coaching sessions, giving learners structured feedback on what to change next.
Recordings, scoring and skill metrics are surfaced to L&D teams so upskilling shows up as data rather than attendance records.
Pre-built pathways and workflows are tailored to leadership, sales, healthcare, education and customer service contexts.
