Show HN: GridPath – AI first desktop app to work with spreadsheets (gridpath.dev)

GridPath has launched as a groundbreaking AI desktop application designed specifically for interacting with spreadsheets, setting itself apart from existing "AI for spreadsheets" tools. One of its standout features is the ability to run multiple workbooks simultaneously, each supported by its own AI agent. Built on a native Rust core rather than Electron, GridPath boasts quick cold starts and a high prompt cache rate, which enhances performance significantly. Users can maintain their original Excel file's integrity, as only prompts are sent to the AI models from providers like Claude or ChatGPT, ensuring data privacy while retaining all advanced Excel features. This platform represents a significant shift in how users can leverage AI for spreadsheet tasks, enabling robust multi-turn interactions that go well beyond the single-turn assistance offered by tools like Excel Copilot. GridPath allows users to conduct complex operations—such as fetching web data and making numerous formatting changes—in a streamlined workflow that emphasizes user control over edits. It supports cross-sheet references and includes safety nets for changes, with features like in-session undo and robust backup protocols. With plans to support additional formats and compatibility with Linux, GridPath is poised to transform spreadsheet management for tech-savvy users.
