  • •Rust + Tauri core delivers ~75% prompt cache rate and instant cold starts.
  • •Uses your existing Claude or OpenAI subscription with no markup.
Weaknesses
  • •Charts display but don't render in view; pivot tables not yet supported.
  • •Excel Copilot and Google Sheets AI are well-funded competitors in this space.

Post Description

Hi HN — I built GridPath as I wanted something that runs like Cursor for spreadsheets - parallel workloads, reversible changes, tool set customized for spreadsheet work, connection to multiple model providers. It's a Tauri/Rust desktop app, free to use, just connect your Claude token or sign in with OpenAI subscription.

A few things that were interesting to figure out: you can get very close to Excel with just Univer free license, the most material missing elements are charts (existing charts kept but not displaying in the view) and pivot tables. Rust + cutting down on tools available to the model (basically just web fetch + talk to user + excel operations) improves the speed materially. SpaceX model built in 2 min 30s, compared to ~5 min for Excel plug in. Working next on improving the agent efficiency for multi-sheet work + context compacting for longer sessions.
