More than a chat window.

A chatbot guesses at your numbers. Your team counts them.

  • It does the math. Your team runs the numbers on the file itself, so totals and averages are counted, not guessed.
  • It reads what you have. Excel and CSV sheets, Word documents and PDFs, from the folder you choose.
  • It shows the result. Charts, tables and reports open beside the chat. Change a sheet yourself and your team carries on from your version.
  • It asks first. Every analysis asks before it runs. It works only in your folder, with no internet.

Questions

A free app for Mac that gives you a small AI team. You ask in plain words. Teammates read your files, run the numbers and write it up, and they ask you before anything important.

Excel and CSV sheets, Word documents and PDFs in your folder. It can change a sheet or a document and keep what it did not touch. A scanned PDF that is only pictures cannot be read yet.

Your team counts them on your actual file instead of answering from memory. Before an analysis runs, you see what it will do, and you can ask how any number was reached.

No. Ask in plain words. Your team writes and runs the analysis itself, and sets up what it needs the first time.

Your files stay on your Mac. Analyses run on your Mac, inside your folder, with no internet. The AI model you connect only sees what your team sends it.

ARK is free. Your team runs on the AI you already pay for: a Claude or ChatGPT subscription, an API key, or a free model on your Mac.
