Keinsaas Navigator
An open-source AI chatbot workspace for individuals and teams, combining multiple LLM providers, MCP tools, visual workflows, custom agents, and a realtime voice assistant.
Keinsaas Navigator, originally created as Better Chatbot by Choi Sung Keun, is an open-source AI chatbot and workspace for individuals and teams. It integrates multiple LLM providers (OpenAI, Anthropic, Google, xAI, Ollama and others) behind one interface, and needs only one AI provider API key to run, with the rest of the stack running on free-tier database, storage and hosting services.
Its tools include the Model Context Protocol, web search, JavaScript and Python code execution, and data visualization, and it supports generating and editing images, building custom agents and visual workflows that become reusable tools, sharing agents, workflows and MCP configurations with a team, and a realtime voice assistant with full MCP tool integration. Any feature can be invoked directly by @mention in the chat.
It is built with the Vercel AI SDK and Next.js and deploys with one click to Vercel.
