Coot

Coot is a free desktop app that runs AI on hardware you control, working over your documents, email and calendar without uploading them. It handles private document search, inbox triage, scheduled automations and multi-step agents for individuals, teams and companies.

A model hub picks local models that suit your machine, and private retrieval lets you ask questions of your own PDFs, notes and connected drives. In the inbox it can summarise, sort and draft replies, and it can collect receipts into monthly summaries or pull email, Slack and spreadsheets into one shareable view. Skills and memory carry know-how between sessions.

For businesses it suggests uses across finance, HR, sales, support and IT, such as turning invoices into organised books, summarising CVs or drafting support replies from a knowledge base. A visual workflow builder runs tasks on a schedule. The download is for macOS, and enterprises can deploy it over large data stores on their own infrastructure.
