7 Elite AI Models
Choose from the best models across Google, OpenAI, and Anthropic. Switch providers instantly from a single dropdown inside the chat input — no page reload, no friction.
Typewriter Streaming
Responses feel alive. AiChat animates AI replies character-by-character, just like watching the model think in real time — no jarring full-text pop-ins.
Full Markdown Rendering
Responses render beautifully — bold, italic, lists, inline code, and syntax-highlighted code blocks with a one-click Copy button.
Client-Side Key Security
Your API keys live only in your browser's localStorage. Never uploaded to any server, never logged, never shared. You are always in full control.
Persistent Chat History
Every thread is automatically saved. Browse recent conversations in the sidebar, rename for context, or delete what you no longer need — all with one click.
Dark & Light Mode
AiChat ships with a polished dark theme and a clean light mode. Toggle instantly from the sidebar — your preference is saved for next time.
Background Glow Effect
An optional radial gradient glow behind the chat area adds a premium, immersive atmosphere. Enable or disable from Appearance settings in one tap.
Fully Responsive
Built to work on any screen — desktop, tablet, or mobile. The sidebar auto-collapses on small screens and opens with a hamburger menu.
API Key Manager
A dedicated Settings panel lets you add, update, or clear your Gemini, OpenAI, and Anthropic keys with instant visual status indicators.

Built with your privacy as the default.
AiChat is a client-side application. This means:
- ✅ Your API keys are saved only in your browser — never on our servers.
- ✅ Every AI request goes directly from your device to Google, OpenAI, or Anthropic.
- ✅ We have zero access to your conversations or credentials.
- ✅ Clearing your browser data deletes everything — no data persists on our end.
A workspace you'll actually enjoy.
AiChat is built with a premium design system using the Outfit and Inter typefaces, a deep slate dark theme, and smooth micro-animations. Every detail — hover effects, transition timings, code block styling — is tuned to feel fast, modern, and professional.
