Godwit
Open-source email client with an AI assistant for reading, summarizing and drafting replies
About Godwit
Godwit is an open-source email client designed for macOS, Windows and Linux that integrates an AI assistant named Wit. It synchronizes with any IMAP or SMTP account and provides offline access with full-text search and HTML composition. The assistant reads incoming messages, summarizes content, translates text, and drafts replies using user-selected AI models. Wit can process attachments such as PDFs, Office files and CSVs, and offers features like tone adjustment, length modification and quick-reply suggestions. Users retain control over all actions, as Wit never sends messages without explicit approval. Setup is automated for major providers including Gmail, Outlook, iCloud and various regional services. The client supports extensions through TypeScript plugins and MCP servers, enabling custom functionality and integration with external AI agents.
