What is x.ai ?

x.ai created an intelligent assistant named Amy (or Andrew), whom you CC in email chains to handle scheduling. The assistant reads natural language requests, “Find time next week with Sarah for 30 min,” then cross-references calendars, negotiates times, and confirms meetings on your behalf, effectively mimicking a human scheduler. It supports buffer times, preferred meeting durations, and location suggestions. While x.ai is sunset, its scheduling model remains influential and partially carried by newer services like Sidekick.ai, carrying forward the same AI workflow concept
