What reviewers say
Plenty of reviews
Large G2 base (about 1,000 reviews), but G2's pages wouldn't load for us, so G2 themes come from its published pros/cons summary as shown in search results. The same goes for the Trustpilot excerpts.
Recurring praise
- Fast no-code setup; a working agent within an hour. G2
- Natural-sounding voices. G2 Trustpilot
Recurring complaints
- Pricing is high with no middle plan, and key features are locked behind enterprise. G2 Trustpilot
- Reliability: agents going off-script, and SMS and webhook triggers failing. Trustpilot
- Slow or generic support replies. Trustpilot
- Some reviewers say cancelling was difficult and billing didn't stop cleanly. Trustpilot
“The AI agents suffer from severe hallucinations, frequently deviating from their programmed instructions to provide completely irrelevant or nonsensical responses.”
