What is Janitor AI?

Janitor AI is a platform for building and chatting with custom virtual characters. You define their backstory, tone, and behavior, and the AI takes care of the responses using natural language processing.

It launched in June 2023, created by Jan Zoltkowski, and gained over 1 million users in the first week. By 2025, the platform sees over 1.4 million daily active users and continues to grow with a strong community and new features. Click Here: Discover the power of Janitor AI for efficiency

How Janitor AI Works

Here’s the basic flow:

You send a message to a character.
The AI model (like GPT or KoboldAI) processes it.
Your character responds based on its settings and backstory.

Each conversation feels natural because Janitor AI includes memory features and real-time responses. That means your characters can remember previous chats, making the experience more engaging.

Creating a Character (Examples Included)

You can pick from thousands of community-created characters—or make your own.

Creating Your Own Character:

Name: Choose something unique.
Backstory: Define their origin, job, mood, etc.
Behavior: Decide how they respond (e.g., funny, helpful, sarcastic).
AI Model: Choose between GPT-4o, GPT-3.5, or KoboldAI depending on speed and budget.

Example Characters:

A sarcastic medieval knight who tells jokes in battle.
A space explorer tutor who helps you learn science facts.
A virtual therapist who listens and offers emotional support. Read Here: Boost productivity with Janitor AI today!

Keeping Janitor AI Safe

Janitor AI is still in beta, so user safety depends on both platform moderation and your own habits. Here’s how to stay protected:

Safety Tips:

Use a unique password that you don’t use on other platforms.
Avoid sharing personal info (real names, emails, addresses).
Disable NSFW content if you prefer a clean experience.
Use trusted API sources only, especially if integrating 3rd-party services.

UK Access Update:

In July 2024, UK access was blocked due to the Online Safety Act. This law required biometric ID verification costing $1.5 per user, which wasn’t viable. UK accounts remain safe, but new logins are restricted.
