genspark-ai/genoffice

GenOffice is a free, open-source desktop AI Office suite for Word, Excel, PowerPoint, PDF, Markdown and HTML files, with a CLI, agent skill and MCP server so coding agents can produce real Office files locally. AI features are optional and route through the Genspark proxy or your own model provider, while file operations run on your machine.

Project overview

It combines local .docx/.xlsx/.pptx creation and editing with a headless CLI and MCP interface, letting Claude Code, Codex, Cursor and other agents generate real Office files without a window.

Project type: MCP · AI Agent · Document Processing
Use cases: Documents & Office · Knowledge Q&A · Data Analysis · Automation
Deployment: Refer to project documentation
License: Apache-2.0

Best for

General users who want a free, open-source desktop suite that creates and edits real .docx/.xlsx/.pptx files locally, with an AI panel for natural-language editing and review.
Developers who want coding agents such as Claude Code, Codex, Cursor, Gemini CLI, Copilot, OpenCode or Windsurf to produce real Office files via a CLI, agent skill or MCP server.
Users who need on-device PDF/Markdown/HTML conversions and a local full-text search over their documents, with only AI calls leaving the machine.

Key capabilities

Edits .xlsx files with live formulas, charts, pivot tables and an in-house Rust xlsx engine.
Generates .pptx decks from prompts, slide by slide onto the canvas, fully editable.
Provides a block editor over plain .md files with Ask AI, and an AI HTML page/UI builder that produces self-contained .html files.
Indexes names, folders and extracted text of Office/PDF/Markdown/HTML files on-device in a SQLite full-text index with CJK-aware tokenizing, with optional TypeSafe Jev reranking.
Headless command line to inspect, convert, create, read and edit Word, Excel, PowerPoint, PDF, Markdown and HTML; installs with the app and never sends a document anywhere.
Bundled skill so Claude Code, Codex, Cursor, Gemini CLI, Copilot, OpenCode and Windsurf can drive genoffice to produce real Office files.
An ee/ directory is reserved for future enterprise modules under a separate license; these are planned and not yet available.

Limitations and risks

The ee/ directory is reserved for future enterprise modules under a separate non-Apache license, so future enterprise functionality may not carry the same license terms as the main suite.
AI model calls are optional and route through the Genspark proxy (Claude, GPT and Gemini families) or a user-configured key for any OpenAI-compatible endpoint, including local servers; AI features are therefore not part of the on-device file pipeline, and cost and telemetry details are not documented.
This is a native desktop suite with no documented hosted web service, so environments that cannot install desktop apps are unsupported.

Getting started

Download the latest release for your OS (native installers exist for macOS, Windows and Linux), install the native app, open a file and use the AI panel. The app works without configuration when signed in with Genspark.

Alternatives and comparisons

Self-hosted, open-source AI presentation generator with editable PPTX/PDF export, flexible model providers (BYOK or local via Ollama), templates and an API; suits users focused on slides rather than full Office editing.
An open-source AI slide studio inside the Codex coding agent with live steerable generation, durable local projects and PPTX/PDF export; relevant if slide generation via a coding agent is the primary need.
Fair-code platform for building and deploying AI agents and workflow automation with a visual canvas and many integrations; a broader automation platform rather than an Office file editor.
