The project that grabbed attention is ArtCraft, from software engineer Brandon Thomas, who first shared the tools on Reddit. The lineup now stands at 13 free, open-source desktop apps, built mostly with Anthropic’s Claude Opus 5.5 model. The first batch copied Adobe’s creative tools, including a Photoshop stand-in called PhotoCraft.
Less than two weeks later came three Office clones, apparently because people kept asking: WordCraft for documents, DeckCraft for slides and GridCraft for spreadsheets. They open and save the same .docx, .pptx and .xlsx files that Microsoft’s apps use, so you can pass files back and forth. WordCraft even includes tracked changes, comments and a compare tool, and its developers say it covers 97% of the commands in their own list of Word features.
The apps also run on Windows, Mac and Linux, and their code is free to inspect or change under open-source licenses. They are independent projects with no endorsement from Microsoft.
