GoKawiilDeveloper uses Claude AI to build open-source clones of Word, Excel, PowerPoint
Developer Brandon Thomas, who previously built free alternatives to Adobe Creative Cloud apps using Claude AI, has now created WordCraft, GridCraft, and DeckCraft—open-source replicas of Word, Excel, and PowerPoint. The apps are written in Rust with Anthropic's Claude Opus 4.5 and released under MIT or Apache 2.0 licenses, running natively across Windows, macOS, Linux, BSD, and the browser via WebAssembly. WordCraft already supports .docx and other formats with offline spelling and grammar tools, while GridCraft reportedly implements 89% of Excel's ribbon commands and 98% of its worksheet functions.
