Janitor AI

Janitor AI is a web-based platform launched in 2023. It allows anyone to create and interact with customised AI-driven characters without coding. The platform combines a chatbot builder, role-play studio, and integration hub. This setup helps creators, writers, businesses, and educators design conversational agents with unique personalities.

Unlike traditional bots that rely on rigid question-and-answer scripts, Janitor AI focuses on personality and storytelling. Users define traits, backstories, conversation styles, and example dialogues to guide the large language model (LLM) that powers each character. The platform offers its own free JanitorLLM and can connect to external models like OpenAI’s GPT-4, Anthropic’s Claude, or locally hosted models using tools like KoboldAI.

The interaction process has four steps. First, a user submits a message. Next, Janitor AI analyses the text for grammar, intent, and context. Then, the selected LLM generates a response based on the character’s defined personality and scenario. Finally, the reply is given in a natural tone. This structure promotes smooth transitions from casual conversation to complex role-play while keeping the character’s voice intact.

Key features include flexible persona design, detailed personality customisation, and context handling with emotional nuance. Users can adjust tone, boundaries, and answer styles. This allows for applications in tutoring, coaching, customer service, creative writing, or game character prototyping. Businesses can use the system for quick support agents or onboarding simulations, while creators and gamers can explore interactive narratives.

Privacy and security are core to the platform. Private chats are the default setting, with explicit options for public visibility. Costs depend on the chosen model. JanitorLLM is free, while external LLMs follow their own usage-based pricing.

Janitor AI launched in June 2023 by Jan Zoltkowski as a web-based platform for creating and interacting with customised AI characters. From the beginning, it aimed to provide a conversation experience that went beyond strict question-and-answer scripts. The platform combined a chatbot builder, a role-play studio, and an integration hub, allowing users to design characters with unique personalities, backstories, and dialogue styles.

The launch quickly gained attention. Reports indicate that within its first week, Janitor AI attracted over one million users. Early adoption was fueled by the platform’s flexibility and users' ability to create and share their own characters. Writers, gamers, educators, and businesses found the service helpful for storytelling, prototyping non-player characters, and experimenting with interactive teaching or support agents.

As the user base expanded, the platform introduced various technical upgrades. It added support for multiple large language models, including its own JanitorLLM and external options like OpenAI’s GPT series, Anthropic’s Claude, and locally hosted models using tools like KoboldAI. This feature allowed users to choose models based on their needs for cost, speed, or processing power. Janitor AI also improved tools for defining character traits, conversation scenarios, and example dialogues, helping creators maintain consistency in their characters’ voices and behavior.

With rapid growth, challenges in content moderation and policy compliance emerged. Some users faced restrictions or bans when their activities conflicted with the usage rules of external providers. Discussions about safe content, privacy settings, and managing explicit material became common in the community. The platform addressed these issues by implementing clearer privacy controls, ensuring that chats were private by default and that public visibility required explicit consent.

By 2025, Janitor AI had become a versatile tool for both creative and professional use. Its mix of character-driven interaction, flexible model integration, and community growth established it as a key player in the changing landscape of conversational artificial intelligence.

Janitor AI’s mission is to help people and organisations have meaningful conversations with artificial intelligence. The platform offers tools for creating and managing custom AI personas that support education, entertainment, customer service, and creative projects without the need for programming skills. 

By providing easy integration with multiple large language models, Janitor AI aims to give users control over costs, speed, and capabilities while keeping privacy and security intact. Its goal is to make conversational technology available to writers, learners, businesses, and developers. This encourages responsible innovation and continuous improvement in how humans and AI interact in many different settings.

Janitor AI envisions a world where interactive artificial intelligence is a natural part of learning, communication, and creative work. The platform aims to create a trusted space for individuals and organisations to design and interact with AI characters that can inform, support, and entertain. 

By offering easy-to-use design tools along with a selection of leading language models, it seeks to reduce barriers to using AI and encourage responsible use. Its long-term goal is to help people create personalised, context-aware digital companions and assistants that improve education, business operations, and storytelling, while upholding strong privacy and ethical standards.

Janitor AI offers a web-based platform that enables users to create and manage conversational AI characters without needing to code. Its main product is an integrated chatbot builder, a role-play studio, and an AI integration hub. This setup allows individuals and organisations to design characters with distinct personalities, backstories, and dialogue patterns suitable for education, entertainment, customer service, and creative projects.

The platform’s primary service is its character creation tool. Users define traits, scenarios, and example dialogues through a simple web interface. They then select a preferred large language model to power the character. Janitor AI provides its own in-house JanitorLLM, available for free, along with external models like OpenAI’s GPT series, Anthropic’s Claude, and locally hosted models accessed via tools such as KoboldAI. This flexibility lets users balance factors like speed, cost, and processing power.

Janitor AI also has integration services through an application programming interface (API). Businesses and developers can link their AI characters to websites, messaging platforms, or internal systems for tasks such as customer support, onboarding simulations, and content organisation. The API makes it easy to test new ideas and switch between language models as project needs change.

Additional features include persona customisation options that determine tone, conversation style, and memory, which help characters maintain context and respond naturally in different situations. Privacy and security settings enable creators to keep chats private by default or share them publicly if they wish. The platform supports ongoing improvement, allowing small updates to prompts and example dialogues to enhance the character’s performance over time.

Through these products and services, Janitor AI offers a practical way for writers, educators, businesses, and hobbyists to create engaging conversational experiences and deploy them across a range of digital environments.
