DeepLifeStudio/DeepSeekAI

Browser extension for invoking the DeepSeek AI large model.

What it solves

DeepSeekAI is a browser extension that provides a private, AI-powered co-pilot accessible anywhere on the web. It eliminates the need to switch tabs to interact with an AI assistant by bringing the chat interface directly into the browser's content area through floating windows and inline selection tools.

How it works

The extension uses a content script to track text selections and keyboard shortcuts, which then communicates with a background service worker. This service worker acts as a proxy, sending requests to an OpenAI-compatible API endpoint (such as DeepSeek, OpenRouter, or self-hosted providers) and streaming the responses back to the user's interface.

Who it’s for

Users who want a seamless, integrated AI assistant in their browser that supports multiple API providers and prioritizes privacy by storing API keys and preferences locally on the device.

Highlights

  • Inline Assistants: A quick-action bubble appears upon text selection with templates for translation, summarization, and analysis.
  • Floating Workspace: A draggable, resizable chat window with a persistent minimize feature and support for reasoning traces (e.g., DeepSeek-R1).
  • Flexible Provider Support: Compatible with any OpenAI-compatible endpoint, including official DeepSeek, SiliconFlow, and various cloud providers.
  • Privacy-First: No intermediary servers or telemetry; all API keys and keys are stored in chrome.storage.sync.
  • Reading Experience: Integrated support for Markdown, LaTeX math rendering, and syntax highlighting for code blocks.
  • Keyboard Shortcuts: Customizable Chrome commands for toggling or showing/hiding the chat session.
