Synthflow AI Review 2025: Pros, Cons, Features & Pricing

Synthflow AI, launched in 2023, offers a no-code, drag-and-drop platform for creating AI voice agents, featuring integrations with tools like OpenAI's GPT-4o and ElevenLabs for human-like voice agents. Despite its promise of quick and simple setup, Synthflow faces challenges with customization, support, and performance, leading many users to seek alternatives like Retell AI. Retell AI provides a low-code solution with superior customization, scalability, and a pay-as-you-go pricing model, appealing to businesses requiring more control and reliability. Synthflow's BELL framework aims to streamline the voice AI lifecycle, but users report issues with functionality and support, which Retell AI addresses with better customer service, advanced compliance, and lower costs. Synthflow's pricing model can become costly for businesses exceeding their allotted minutes, whereas Retell AI offers competitive rates and flexible plans that cater to larger, more complex needs.
