What is Vt?
Introducing VT Chat, a privacy-first AI chat application that maintains all conversations while offering advanced research capabilities and access to models including Claude 4 Sonnet, Claude 4 Opus, O3, o3, Gemini 2.5 Pro, and DeepSeek R1.
The key differentiator is its truly local-first architecture. All chats are stored in an indexed DB with zero server storage. You can switch between OpenAI, Anthropic, Google, and other providers to compare responses with complete data isolation on your own machine.
Research features include:
- **Deep Research** for multi-step investigations with source verification.
- **Pro Search**, integrating real-time web searches with grounded web searches powered by Google Gemini.
- Document processing for PDFs, a **"Think Mode"** to observe full AI reasoning, and structured extraction to convert documents into JSON.
- AI-driven semantic routing that automatically activates tools based on your queries.
Built with Next.js 14, TypeScript, and Turborepo. The hosted version offers most features for free, with an optional VT+ upgrade for advanced models and premium research tools.
