WordCraft, GridCraft, and DeckCraft replicate Word, Excel, and PowerPoint respectively, with varying degrees of feature parity. WordCraft supports .docx and other formats, includes offline spelling/grammar checks, and mimics Word’s ribbon and tools. GridCraft claims 89% of Excel’s ribbon commands and 98% of worksheet functions, while DeckCraft targets full PowerPoint parity at 79% feature completion. All three are in alpha, with WordCraft the most advanced at 88% feature parity. Thomas built them in Rust under MIT/Apache 2.0 licenses, but they require significant work before replacing Microsoft Office.","keyPoints":["Brandon Thomas used Claude Opus 5.5 to generate open-source Microsoft Office replicas: WordCraft, GridCraft, DeckCraft","WordCraft supports .docx, offline editing, and 88% of Word’s ribbon commands; GridCraft has 89% of Excel’s ribbon","All apps are in alpha, with 60% overall feature parity; Thomas says they need more work before viability"],"whyItMatters":"If successful, these could challenge Microsoft’s dominance in productivity software, proving AI can replicate complex apps. For now, they’re proof-of-concept tools, but the approach could accelerate open-source alternatives.","category":{"slug":"marketing","name":"Marketing & Small Business","url":"https://digestai.news/category/marketing"},"entities":{"companies":["Microsoft","Adobe"],"models":["Claude Opus 5.5"],"people":["Brandon Thomas"]},"firstPublishedAt":"2026-10-13T06:53:00Z","updatedAt":"2026-10-13T06:53:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"techspot.com","title":"The developer who cloned Photoshop using AI has now created Word, Excel, and PowerPoint replicas with Claude","url":"https://techspot.com/news/114179-developer-who-cloned-photoshop-using-ai-has-now.html","publishedAt":"2026-10-13T06:53:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"AI Agents Rewrite Software and Clone Office","url":"https://digestai.news/thread/open-source-rea-hits-100-000-github-stars-as-ai-agents-decompile-software","storyCount":2},"cite":{"text":"Digest AI, \"Brandon Thomas releases AI-generated Microsoft Office replicas with Claude Opus 5.5\", 13 October 2026, https://digestai.news/story/brandon-thomas-releases-ai-generated-microsoft-office-replicas-with-cl","publisher":"Digest AI","title":"Brandon Thomas releases AI-generated Microsoft Office replicas with Claude Opus 5.5","datePublished":"2026-10-13T06:53:00Z","url":"https://digestai.news/story/brandon-thomas-releases-ai-generated-microsoft-office-replicas-with-cl"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
