Free AI

A 100% free, open-source web application that gives anyone instant access to powerful artificial intelligence — no sign-up, no credit card, no limits.

Chat with Groq's LLaMA models directly from your browser using your own API key. Your key never leaves your device.

• Multi-language support — English and Finnish UI with locale-aware translations
• Open-source — released under the MIT License
• Responsive design — works on desktop and mobile

Security Features

• Rate limiting on all public API routes — 30 req/min for chat, 10 req/min for contact
• CSP + HTTP security headers — prevents XSS, clickjacking, MIME sniffing
• Input sanitization — HTML escaping, CRLF stripping, length limits on all inputs
• Honeypot anti-spam on the contact form
• Groq error mapping — raw provider errors are never shown to end users
• API key expiry — stored keys automatically expire after 30 days

---

How It Works

1. User visits /chat and enters their own Groq API key → stored in browser localStorage
2. When sending a message, the key travels from the client through our serverless route (/api/chat) to Groq's streaming API
3. Responses stream back via Server-Sent Events for instant display

Your API key never touches our servers — it travels only: your browser → our proxy → Groq → back. We have no access to it.
