Chat Assistant Box

Chat Assistant Box is a polished AI chat PWA that feels like a native app.

• Pick GPT-3.5, GPT-4o, or Claude models and keep the experience fast with local drafts/history.

• Export conversations as JSON, TXT, or Markdown and copy responses with one tap.

• Toggle “Use Your Own API Key,” paste your OpenAI or Anthropic key, and every request is sent directly from your device so the key never touches our servers.

• The interface stays keyboard-aware, supports light/dark themes, and even lets you listen to replies or retry on rate limits.

• Offline-ready service worker, install prompt, and a responsive layout keep the experience smooth on phones.

Install Chat Assistant Box for a secure, feature-rich AI chat that adapts to your workflows.
