Retell AI
The most granular, itemised pricing in the category — and the easiest honest cost model to audit.
Retell publishes a full component breakdown: voice infrastructure, TTS, each LLM, and every add-on priced separately. That is unusual and genuinely pro-buyer — you can model your real cost per minute before signing anything. It is also the most generous free start, with $10 in credits and 20 concurrent calls at no cost. The trade-off is that the headline '$0.07–$0.31/min' is a wide band, and your actual rate depends entirely on which model you pick.
PhoneBurner
Not an AI voice agent — a very transparent human power dialer that keeps reps on the phone.
We are ranking PhoneBurner honestly rather than conveniently: it is not an AI calling platform. It is a human-powered power dialer, and it says so. It earns its position on transparency — every seat price is published — and on doing its actual job well. If your problem is rep talk-time rather than replacing reps, this solves it without any AI risk. If you came here for autonomous AI calling, this is not that product.
