What Is JanitorAI?

JanitorAI is a free, community-driven AI character chat platform. Instead of paying for a built-in model, you connect your own API key (e.g., popular LLM providers) and then chat with thousands of user-created characters. The result is huge flexibility, no built-in content filters, and a vibrant library—balanced by a slightly more technical setup and potential API usage costs.

How JanitorAI Works

JanitorAI acts as the front end: characters, prompts, memory, and UI. The language model comes from the provider you connect via API key. That means you control speed, style, and price by choosing your model—great for power users, slightly confusing for beginners.

Roleplay & Content Freedom

Because content filtering is not the platform’s focus, JanitorAI supports unfiltered roleplay (within laws and provider terms). You’ll find romance, fantasy, sci-fi, slice-of-life, and adult scenarios. Quality depends on the character prompt and the model you pick; the best creators deliver surprisingly consistent personas. Note: NSFW is for 18+ users only. Always follow local laws and the terms of your model provider.

Character Library & Creation

The site features thousands of community characters with tags, ratings, and frequent uploads. Creators can edit system prompts, add lore, memory cues, and behavior notes—powerful tools for crafting personalities or kink-specific dynamics.

Setup & Ease of Use

If you’ve never used API keys, the initial setup can feel technical: you’ll paste a key, select a model, and tune settings. Once connected, the interface is straightforward—quick character search, favorites, and chat history.

Pricing & Value

The platform itself is free. Your cost comes from the API provider you choose, which can be extremely cheap for light usage but adds up under heavy chat. This model is perfect if you want control over spend and performance.

Who Is JanitorAI Best For?

If you want maximum freedom and control, JanitorAI is one of the best ways to chat with AI characters for free—you only pay your chosen provider. The trade-offs are a DIY setup and inconsistent quality across community characters. Power users will love it; beginners may prefer a turnkey app.

Frequently Asked Questions

Is JanitorAI completely free to use?

Yes, the platform itself is free. JanitorAI is a front end for chatting with community characters. You connect your own LLM API key, and you only pay the API provider based on usage. Light chatting can cost pennies; heavy roleplay sessions or large context windows can add up. Prices and limits depend on the provider you choose.

How do I set up an API key for JanitorAI?

    1. Choose a provider (any supported LLM).

    2. Create an account with that provider and enable billing/credits.

    3. Generate an API key in the provider’s dashboard and copy it.

    4. In JanitorAI → Settings (or Account/API), select the provider and paste the key.

    5. Pick a model and optional parameters (temperature, max tokens, context). Save.

    6. Test a chat with any character. If you see errors, check that your key is valid, you have credit, and your model/region is supported.

    (Tip: keep the key private; rotate it if it leaks.)

Does JanitorAI allow NSFW content?

Yes—JanitorAI is NSFW-friendly (18+). The site itself applies minimal filtering, making it suitable for unfiltered roleplay. However, what’s allowed also depends on your API provider’s policies and local laws. Use block/report tools as needed and avoid sharing sensitive personal data.

Can I create and share my own characters?

Absolutely. Use the character builder to set name, bio/backstory, system prompt, greeting, memory/lore notes, tags, and avatar. Save the character as private, unlisted, or public. Public characters can be discovered by the community; you can update prompts anytime and share a direct link.
