Rapid Chat ⚡
The AI assistant that respects your privacy
Zero cloud storage • Ultra-fast streaming • Multi-model reasoning • Fully open source
No signup required • No data collection • No vendor lock-in
Built Different
Every feature designed for privacy, performance, and developer control
Privacy-First Architecture
Zero cloud storage. All chats, uploads, and interactions stay 100% local in your browser (IndexedDB). No telemetry, no analytics, no data ever leaves your device.
Ultra-Fast + Streaming UI
Token-level streaming, live TPS monitor, minimal UI latency. Feels faster than commercial tools with <think> tag rendering and inline markdown previews.
Multi-Model Access
Choose from multiple specialized models for different tasks (coding, research, summarization). Integrated tool calling for Wikipedia, Weather, Whisper, and more.
Dev-Centric UX
Keyboard-first interface with Command Palette. Clean markdown rendering. All interactions are inspectable and debuggable — made for builders.
BYOK (Bring Your Own Key)
When self-hosting: plug in your own API keys for OpenAI, Gemini, Groq, and other providers. No usage markup — you pay providers directly.
Fully Open Source
Built with Next.js 15, React 19, and Tailwind 4. Entirely self-hostable — no vendor lock-in, no backend needed.
Why Developers Are Switching
No cloud, no tricks. Just fast, private AI that you control.
