In summary
Calendly
Excellent at pure booking. If you just need to schedule (no payment, no integrated video, no AI), Calendly remains unbeatable.
Stripe Billing
The reference for complex recurring billing. But doesn't do booking, video, or AI. Must be combined with other tools.
Fireflies.ai
The best at pure AI transcription/summary. But doesn't do booking, payment, or secure video. Complementary, not an alternative.
