FAQ

Does it work on Wayland?

No. Run on X11 or use XWayland.

Does it affect my active window?

No. xlib mode creates an invisible off-screen window. Keystrokes never reach your active app.

Any memory leak or leftover processes?

No. The hidden window lives only while the process runs. On exit everything is cleaned up automatically.

What is the difference between --pause and --activity?

• --pause — fixed wait between phrases (recommended for human-like cadence)
• --activity — percentage of time spent typing (continuous rapid mode)
