The Verdict
Cal.ai is built for busy professionals and sales teams, with a focus on natural-language-scheduling and conflict-resolution. Notion Calendar targets notion users and freelancers and leads with time-blocking and availability-sharing.

Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Notion Calendar offers broader built-in capabilities (7 features vs 6), while Cal.ai takes a more focused approach — which can mean a simpler, faster onboarding experience.
