Introducing VT Chat
Introducing VT Chat, a privacy-first AI chat application that keeps all your conversations local while providing advanced research capabilities and access to 15+ AI models including Claude 4 Sonnet and Claude 4 Opus, O3, Gemini 2.5 Pro and DeepSeek R1.
The core difference is true local-first architecture. All chats are stored in IndexedDB with zero server storage. Your API keys never leave your browser, and I can't see them even as the developer. You can switch between OpenAI, Anthropic, Google and other providers to compare responses, with complete data isolation for shared machines.
Research features: Deep Research does multi-step research with source verification, Pro Search integrates real-time web search with grounding web search powered by Google Gemini. There's also document processing for PDFs, a "thinking mode" to see complete AI reasoning, and structured extraction to turn documents into JSON. AI-powered semantic routing automatically activates tools based on your queries.
Built with Next.js 14, TypeScript, and Turborepo in a monorepo setup. Everything is fully open source for self-hosting with your own API keys. The hosted version keeps most features free, with optional VT+ for premium models and advanced research capabilities.
This is such a powerful launch , a local, privacy-first AI chat tool that taps into 15+ models is seriously next level. And the open-source angle? Gold for builders and teams that want full control.
I work with a skilled team of digital marketers and copywriters who help early-stage founders like you bring their products into the spotlight through smart content, targeted visibility, and user-focused messaging that gets real traction.
If you’re ever looking to boost awareness, build a presence, or just get VTChats in front of the right early users, I’d love to connect or contribute. You’re building something meaningful here. Great job again.
Hi Helen, thank you for checking out VT Chat.
