What it solves

Keinsaas Navigator is an open-source AI chatbot platform designed for individuals and teams to consolidate multiple AI services into a single, highly extensible interface. It eliminates the need to switch between different AI providers and provides a powerful set of tools for automation, data visualization, and browser control.

How it works

Built with Next.js and the Vercel AI SDK, the platform integrates with major LLM providers (OpenAI, Anthropic, Google, xAI, Ollama) and supports the Model Context Protocol (MCP) to allow the AI to interact with external tools. It features a visual workflow builder to chain LLM nodes and tool nodes into reusable automated sequences, and a system for creating specialized AI agents with custom instructions.

Who it’s for

Users who want a self-hosted, feature-rich AI assistant that supports multiple models, custom tool integration via MCP, and collaborative team features.
