## Introduction / Main Floor: Everfern: Open-Source Local AI Desktop Agent, Free Alternative to Claude Cowork

Everfern is a completely free, local-first AI desktop agent that can operate computers like humans—clicking buttons, navigating apps, filling forms, and running workflows. No subscriptions, no cloud dependency, data never leaves your local machine. It's an open-source alternative to Claude Cowork and Manus Desktop.

## Project Overview

Everfern is a revolutionary open-source AI desktop agent project developed by the CodenRust team. It allows users to control their computers via natural language commands, enabling AI to perform various operations like humans—from opening apps and clicking buttons to filling forms and running complex workflows. Unlike commercial products such as Claude Cowork and Manus Desktop, Everfern is completely free and runs entirely locally; user data never leaves their machine.

The core philosophy of this project is "Local-First". In an environment where most AI applications rely on cloud processing, Everfern provides a privacy-friendly and cost-controllable alternative. Users can use local models (like Ollama, LMStudio) for a fully private AI experience, or connect to cloud APIs for stronger capabilities—the choice is entirely in the user's hands.

## Computer Use

The most striking feature of Everfern is its ability to "see" the screen and perform operations. Through screenshots and mouse/keyboard control, the AI can:

- Identify UI elements on the screen (buttons, input boxes, menus, etc.)
- Precisely move the mouse cursor and perform clicks
- Simulate keyboard input to fill forms and documents
- Navigate any desktop app without specific integration

This means users can describe tasks in natural language, such as "Open Spotify and play my favorite songs" or "Refactor the authentication module in VS Code to use JWT tokens", and Everfern will automatically break down the task steps and execute them.

## Navis Browser Agent

Everfern has a built-in browser agent called Navis, a dedicated browser automation component developed from scratch. Unlike traditional automation tools like Selenium and Playwright, Navis is designed specifically for AI interaction:

- Natural language-driven web navigation
- Automatic form filling and data scraping
- Web content understanding and summary generation
- No need to write XPath or CSS selectors

Users just need to say "Search for the latest AI programming tools and create a comparison table", and Navis will automatically complete the entire process of searching, visiting multiple websites, extracting information, and organizing it into a table.

## Document Processing

Everfern supports reading and writing operations for multiple document formats:

- Reading, analyzing, and creating PDF documents
- Editing and generating Word documents
- Data processing for Excel/CSV spreadsheets
- Creating PowerPoint presentations

This simplifies tasks like automated report generation, data organization, and document conversion.

## Code Assistant

For developers, Everfern provides powerful code assistance features:

- Directly write, review, and debug code in editors like VS Code
- Understand the full project context to provide refactoring suggestions
- Automatically execute test and deployment scripts
- Code difference analysis and patch application

## Skill System

Everfern introduces the concept of reusable "Skills". Skills are modules that encapsulate specific workflows, which can be installed from the community or developed by oneself. Each skill teaches Everfern how to handle a specific type of task, and they are shareable, auditable, and attributable.
