Overview

Monadic Chat is a locally hosted web application for creating and utilizing intelligent chatbots. By providing AI models with a real Linux environment through Docker, it enables advanced tasks requiring external tools. With support for voice interaction, image/video processing, and AI-to-AI conversations, Monadic Chat serves both as an AI application platform and a framework for developing AI-powered applications.

Contextual Conversations: Like monads in functional programming that wrap values with context, conversations in Monadic Chat can carry structured metadata (reasoning, topics, notes).

Conversations as Data: Your conversations are persistent, portable data you own—not ephemeral sessions locked in a web service. Edit, delete, export, and import your conversation history freely.

Available for Mac, Windows, and Linux

Why Monadic Chat?

Unlike web-based AI services or IDE-integrated assistants, Monadic Chat is a locally-run AI platform that gives you:

1. Use Your Preferred Tools: Access real Docker containers to run code, install packages, and persist files.

2. Local Data Storage: Store conversations, code, and files on your local machine, not in cloud services. Work offline with Ollama.

3. Extensible Platform: Not just a chatbot—a framework for building custom AI applications with Monadic DSL.

4. Provider Independence: Switch between 9 AI providers. Choose the best model for each task.

Perfect for: Developers building AI tools, researchers needing reproducible environments, privacy-conscious teams, and anyone wanting full control over their AI infrastructure.
