## Introduction
GenOffice is a free, open-source AI office suite by Genspark that edits real .docx, .xlsx, and .pptx files locally on your desktop. It integrates a built-in AI agent that can draft documents, generate spreadsheet formulas, create slide decks, and convert PDFs to Word — all running on-device with bring-your-own-key LLM access. No cloud upload required.

## What GenOffice Does
- Opens, edits, and saves Microsoft Office formats (docx, xlsx, pptx) natively
- Provides a built-in AI assistant for drafting, summarizing, reformatting, and translating documents
- Converts PDF files to editable Word documents entirely on-device
- Offers a Markdown editor alongside the Office editors for developer-friendly writing
- Runs on macOS, Windows, and Linux with a modern desktop interface

## Architecture Overview
GenOffice is built with TypeScript on an Electron-based shell that embeds specialized editors for each file type. The document editor uses a rich-text engine that reads and writes OOXML directly, preserving formatting fidelity. The AI integration uses a local-first architecture where your API key connects to the LLM provider of your choice — OpenAI, Anthropic, or any OpenAI-compatible endpoint. PDF conversion runs a local parser and layout engine that reconstructs the document structure without sending data to external services.

## Self-Hosting & Configuration
- Download pre-built installers from the GitHub Releases page for your platform
- Configure your preferred LLM provider and API key in the settings panel
- Set the default file save format and auto-save interval
- Customize keyboard shortcuts and editor themes via the preferences menu
- For offline use, point the AI backend to a locally running LLM server

## Key Features
- Full Office file compatibility: edit .docx, .xlsx, .pptx without converting formats
- On-device PDF-to-Word conversion with no cloud dependency
- Bring-your-own-key AI integration supporting multiple LLM providers
- Cross-platform desktop app with native performance
- Privacy-first design: documents never leave your machine
