One chat window, every model you already pay for, and a history that stays in your own browser unless you decide otherwise. Neo Chat connects to Google, OpenAI, Anthropic, and any OpenAI-compatible gateway, so switching models mid-project takes one click. Agent mode runs multi-step tool workflows, and Deep Research drafts a plan for approval before producing a cited report that can be resumed if it stops. Attach files, build a knowledge base for retrieval, and let memory carry preferences between conversations. Browse a market of ready-made assistants and text skills, add OpenAPI plugins or remote MCP servers, and search the web through a configurable service. Answers render Markdown, math, diagrams, and charts, plus editable artifacts and interactive checklists, quizzes, flashcards, and calculators. Voice input and read-aloud sit beside the composer, and optional encrypted sync moves settings between devices. An access password can protect a shared deployment, and a health page checks that everything is configured. Switch models mid-conversation, keep one history, and stop juggling a tab for every provider.
