An advanced, premium browser side panel extension powered by the Deepseek V4 API.
Supercharge your daily workflows! Autonomously browse pages, scrape content, fill out inputs, and stream Chain-of-Thought (CoT) reasoning — all confined to the agent's own Chrome tab group, under granular human-in-the-loop safety switches and glassmorphic UI controls.
Watch Deepseek Browser Agent in action! Check out our live demo videos showing various browser automation scenarios (including technical documentation research, Trilium Notes local setup, device details tool permission prompts, and settings drawer customizations):

Deepseek Browser Agent doesn't just read the page—it controls the browser! Equipped with autonomous client tools, the agent can:
- Scrape Page Text: Extract the primary readable content from any webpage instantly for summary or analysis.
- Extract Page Links: Gather, group, and map out all hyperlinks on the active document.
- Query DOM Structure: Inspect CSS selectors and document layout structures.
- Click & Fill: Interact directly with web buttons, inputs, and text fields.
- Navigate & Open Tabs: Browse to new URLs and open pages as background tabs inside its own tab group, without ever pulling you away from what you are doing.
- Highlight Match Query: Search and highlight occurrences of specific keywords in the DOM.
- Dark Mode (Default): Deep carbon backdrops with neon brand highlights and subtle glassmorphic blurs.
- Light Mode: A beautiful, pristine, high-contrast off-white theme with fully refined alert contrast, soft card borders, and elegant brand color highlights.
- Shadcn Tooltips: Customized Radix UI portals with an instant 10ms hover delay for fluid and responsive visual feedback.
- Its Own Tab Group: The agent works only inside a Chrome tab group named Deepseek Agent. Every other tab in your browser is invisible to it — you keep working undisturbed.
- You Control Access: Drag a tab into the group to share it, drag it out to take it back. Group membership is the permission; there is no separate allowlist to manage.
- Never Steals Focus: Pages are opened and driven in background tabs. The agent switches its own target without changing what you are looking at.
- Storage Safeguards: A live usage meter warns before local storage fills up, every write failure is surfaced instead of silently swallowed, and chats pause rather than pretending to save.
- Protected System Scopes: Safely flags restricted browser domains (
chrome://,devtools://, Chrome Web Store) where content script executions are locked.
- Auto-Saved Sessions: Chat logs are preserved under local scopes (
website-specific,domain-level, orglobal). - AI Session Auto-Naming: Generates creative titles for your conversation logs automatically.
- Cost & Usage Balance Tracker: Directly fetch your Deepseek account balance, token allocation limits, and server statuses.
- Reasoning effort toggles: Stream reasoning chain-of-thought CoT blocks and select from
Low,Medium, andHighreasoning effort levels. - Detailed Tool Calls toggle: Control whether detailed, collapsible tool parameters and execution results are displayed. When disabled, it condenses tool call logs into an elegant, professional separating element containing the exact action count (e.g.
--- 10 tool calls ---), fading beautifully on both sides to keep the conversation clean.
- Core Logic: React 19, JavaScript (ES6+), Vite 8
- Styling: Tailwind CSS 3, Vanilla CSS Post-Processing (for custom theme portals)
- Portals & Icons: Radix UI Select & Tooltip Portals, Lucide React Icons
- Packaging: Chrome Extensions Manifest V3 Specification
Follow these steps to set up and run the extension locally in developer mode:
Make sure you have Node.js (v18 or higher) and npm installed.
git clone https://github.com/your-username/deepseek-browser-agent.git
cd deepseek-browser-agentnpm installThis runs Vite in hot-reloading development mode:
npm run devCompiles and bundles the highly optimized production extension files into the dist/ directory:
npm run buildTo install the built extension in your Google Chrome browser:
- Open Google Chrome and navigate to
chrome://extensions/. - Enable Developer mode by toggling the switch in the top-right corner.
- Click the Load unpacked button in the top-left corner.
- Select the
distfolder inside your project directory (the folder created by runningnpm run build). - Success! The extension icon will now appear in your browser toolbar. Click it or right-click any page and select Summarize Page to launch the sidebar panel!
We love contributions! If you want to help make Deepseek Browser Agent even better, please follow these guidelines:
- Fork the repository and create your feature branch:
git checkout -b feature/amazing-new-feature
- Lint your changes before committing to ensure there are no ESLint syntax or purity errors:
npm run lint
- Validate your build to guarantee compiling is 100% green and compatible:
npm run build
- Commit your changes with clear, concise, and structured commit messages.
- Push to your branch and open a Pull Request explaining your enhancements and visual verification.
- Purity: Ensure all helper functions are pure and declared outside of React render contexts to prevent render-phase lints.
- Contrast: When adding UI colors, ensure they adapt perfectly to both
.lightand.darkbody classes (avoid hardcoded dark values in light mode elements). - Accessibility: Always wrap functional buttons inside
<Tooltip>containers with instant delay duration parameters for optimal developer usability.
We are planning to turn Deepseek Browser Agent into a highly modular, customizable AI copilot. Below is our active roadmap, focusing heavily on equipping the agent with dynamic Modular Markdown Skills and browser automation capabilities. We welcome any contributions or pull requests aiming to check off these items!
- [ ] Markdown-Based Skill Files (
.md):- Equip the agent with the capability to read and execute custom modular Skill files written in Markdown (using standard YAML frontmatter defining name, description, and required parameters).
- Let developers and users drop new
.mdskill files into a/skillsdirectory to dynamically register specialized workflows (e.g., code review, SEO optimization, form auto-filling) that the agent will read and run exactly as documented.
- [ ] Dynamic UserScript / Automation Skill:
- Let users write or install custom JavaScript "skills" (similar to Greasemonkey/Tampermonkey scripts) that the agent can execute autonomously on specific domains.
- Example: An "Auto-Invoice Downloader" skill for Stripe billing portals.
- [ ] Model Context Protocol (MCP) Client:
- Integrate an MCP client inside the sidebar to allow the Deepseek Browser Agent to communicate with local or remote MCP servers (GitHub, local databases, Google Docs, calendars).
- Example: Equip the agent with a "Local Terminal" skill or a "Database Query" skill.
- [ ] Visual Snapshot OCR & Image Decoding Skill:
- Add a snapshot OCR decoding feature that will capture webpage elements or regions, use a 3rd party vision/OCR service (yet to be decided) to convert the images into detailed text descriptions, and feed them into Deepseek (since the current models do not support native image inputs).
- [ ] Real-Time Voice & Speech Skill:
- Integrate Chrome's built-in Web Speech API (transcription & synthesis) to enable fully hands-free browser automation through voice commands.
- [ ] Cost-Efficiency & Token Dashboards:
- Implement a visual card rendering exact token metrics, reasoning output tokens, cache hit rates, and total cost estimates per chat session.
