After Adobe saw its tools cloned with AI, the trend hit Microsoft Office and Figma. ArtCraft released WordCraft, GridCraft, and DeckCraft—reimplementations of Word, Excel, and PowerPoint written in Rust—plus FigCraft for interface design. All are still in development. Meanwhile, REA, a toolkit that connects AI agents like Claude Code to reverse-engineering tools, gained attention for analyzing programs without access to source code. But the details matter: the Office clones operate under rules prohibiting decompilation of Microsoft applications. Their creators describe reimplementations based on public documentation and behavioral observation, without confirming REA's involvement in these projects.
The real threat isn't just cheaper subscriptions. If AI can cheaply reproduce familiar interfaces, shortcuts, and functions, established software companies face pricing pressure and genuine competition. A familiar experience also lowers friction for users who've spent years mastering a tool. Yet appearance is only part of the equation. File compatibility, performance, updates, and support shape the decision to switch. GridCraft itself is in alpha with maintainers estimating only 50% readiness for real work. This shift could move competition away from feature parity toward reliability, integrations, and the ecosystem surrounding the product.
