Windmill is an AI-powered performance management platform designed to make reviews faster, more useful, and grounded in employees’ day-to-day work. Its system builds a context graph of people and their work, drawing on evidence gathered over time so managers do not have to reconstruct a quarter from memory. Windmill says it can make reviews 90% faster and reports 93% employee satisfaction.

The platform supports performance reviews, regular one-on-ones, continuous feedback, onboarding, pulse surveys, offboarding, analytics, and calibration. Its AI assistant, Windy, can check in with new hires through Slack, prepare meeting agendas from recent work, request timely peer feedback, and draft reviews from documented evidence. During calibration, teams can examine rating patterns, identify potential bias or inconsistencies, and trace decisions back to supporting evidence.

Windmill integrates with workplace tools including Jira, Slack, Figma, Notion, Google Workspace, and Asana, with more integrations available. The company offers a free starting option for up to 10 users and provides product demonstrations and pricing information.
