What X1 Search is
X1 Search is a paid Windows application for searching emails, attachments, files, chats, and cloud data from one interface. It searches local files, removable media, network shares, cloud-synced locations, and remote sources, covering file content, email, and messages. Fast-as-you-type search, hit highlighting, full-fidelity previews, and more than 50 metadata filters help narrow results. Users can organize and tag emails, documents, chats, and attachments with customer-enabled AI models running in their environment. Supported sources include Microsoft 365, Teams, SharePoint, OneDrive, Exchange, Slack, Google Drive, Gmail, Box, Dropbox, PST files, Yahoo Mail, and AOL Mail. An MCP connector lets Claude search the local X1 index without uploading whole data sources, subject to listed Windows and software requirements. X1 says indexed content remains under the user's control during ordinary use. Pricing starts at $79 a year per user, with a 14-day full-feature trial and no free plan.
