In just two years, Janitor AI has exploded from a niche experiment into a global playground where writers, gamers, customer-support teams and lonely hearts all meet. Whether you want to co-write a fantasy novel with a sentient dragon, automate repetitive FAQ tickets, or simply banter with an anime crush, Janitor AI promises the tools—and freedom—to do it. Below you’ll find a 360-degree tour of the platform: what it is, how it works, pricing, use-cases, five worthy alternatives, and the five questions new users ask most often.
What Is Janitor AI?
Janitor AI is a browser-based AI character platform that lets you create or import virtual personas and chat with them through cutting-edge large language models (LLMs) like GPT-4, Claude or KoboldAI . Unlike single-purpose chatbots, Janitor AI acts as middleware: it provides the character builder, memory controls, NSFW toggle and immersive UI, while external LLMs supply the raw intelligence. This hybrid design gives you both creative freedom (you decide personality, lore, greeting, temperature) and technical flexibility (pick the model that balances cost, speed and quality) .

Power users can hook up GPT-4 for Oscar-worthy dialogue, while casual visitors can still enjoy unlimited free chats.

Ready to meet your next AI best friend—or build the perfect customer-service elf? Head to Janitor AI and start creating today.
Is Janitor AI free to use?
Yes. You can chat unlimited times using the in-house JanitorLLM Beta at no cost. If you prefer higher-quality responses, connecting your own OpenAI, Claude or KoboldAI API will incur charges from those providers.
Is Janitor AI safe and private?
Chats are encrypted in transit and stored under pseudonymous IDs. NSFW content is opt-in, and no personal data is sold. For maximum privacy, use a local KoboldAI model.
Can I use Janitor AI on mobile?
Absolutely. The site is fully responsive; add it to your home screen as a PWA for an app-like experience on iOS and Android.
Why is Janitor AI slow or down?
Peak-hour traffic can overload the free JanitorLLM servers. Switching to a paid OpenAI or KoboldAI backend usually restores normal speed.
How do I create a character that remembers past chats?
Enable the “Persistent Memory” toggle in the character settings and set a reasonable context token limit (e.g., 2 048). Summarize key events in the “Memory” box so the bot recalls them in future sessions.
