What does nylas tui do?

The nylas tui command opens a full-screen terminal interface for managing email, calendar events, and contacts. Navigate your inbox with keyboard shortcuts, read and reply to messages, and switch between accounts — all without leaving the terminal. The TUI renders rich email content and supports vim-style navigation.

Troubleshooting

TUI shows blank screen or garbled output

Ensure your terminal supports 256 colors and is at least 80x24 characters. Try a different terminal emulator if the issue persists.

No emails shown in TUI

Run `nylas auth whoami` to verify an account is connected. The TUI requires an active grant — run `nylas auth login` if needed.
