"Voice Feature Is Great, but Overall Experience Needs Improvement"
2/5
What do you like best about Synthflow?

I'm looking for voice translation with this tool; let's see if it works. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

I don't like the price, and I don't like the lies either. They told me that just for signing up I'd get 15 minutes, which is a lie. Review collected by and hosted on G2.com.

"Synthflow - Outbound Agent and campaign setup in only 24 hours!"
5/5
What do you like best about Synthflow?

Synthflow provided the most suitable tool for creating a Voice Agent for our very first AI agentic global customer.

Within 24 hours of signing up to Synthflow we have managed to connect it to Hubspot and Zapier to automate campaign triggered Agent Calls.

The agent prompts during agent configuration were straighforward and the selection of voices suited our campaign audience.

We have reviewed many different solutions and this is the best out there for us right now, give it a go! Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

There is an auto-save option instead of a save button for config changes which sometimes crashes if you click through too quickly - what can I say I was eager - but worked around it and it did not pose any real problems to getting a campaign up and running.

"A game-changer for building AI voice workflows"
4.5/5
What do you like best about Synthflow?

I joined Synthflow just a week ago and completed all the courses — and I’m genuinely impressed. The platform makes it incredibly simple to design AI voice workflows without needing to code. The agency functionality is a standout feature — it opens up real business opportunities by allowing you to manage multiple client projects seamlessly. As someone just starting out, this gives me confidence and direction. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

As a new user, everything has been smooth so far, but I’d love to see more real-world templates or use-case libraries to speed up client delivery. A few more third-party integrations would also make it even better. Review collected by and hosted on G2.com.

"Excellent product"
5/5
What do you like best about Synthflow?

What I like the most is the fluency with which the agent handles interventions. The organization of their interventions recorded in a CRM is clearly an advantage over other competitors as it allows for having a schedule and clearly monitoring everything that has been done. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

There should be a trial, with minutes for people to bring the recommendations others give about Synthflow down to reality, since it's not the same as being told about it and being able to try the service oneself, adjusting it to one's own needs. Review collected by and hosted on G2.com.

"Good Value for Simple Call Automation"
3.5/5
What do you like best about Synthflow?

Its Pretty easy to use and learn and has some great features Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

The service is too expensive.

Furthermore, technical errors are unhelpful; I constantly see vague messages like "Failed to create room" when calls fail. Please implement clearer error messages.

Finally, the free plan is too restricted. We need more test minutes to properly evaluate the high-priced service. Review collected by and hosted on G2.com.

"Very user friendly and time saving."
4.5/5
What do you like best about Synthflow?

I really like how quickly you can create an AI call flow that sounds natural and conversational. The ability to design branching logic for different lead responses makes it feel like a real human agent is handling the call.

The most helpful aspect is the combination of AI-driven voice with structured flow logic. It allows me to automatically qualify leads, book appointments, and capture important details without needing to manually script every single response. Integrations with CRMs and calendars are also a huge time-saver. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

Right now, the AI can sometimes misinterpret unexpected responses or pause too long, which can make calls feel slightly unnatural. Also, setting up complex branching logic can be a bit tricky until you’re familiar with the interface. Review collected by and hosted on G2.com.

"So far so good"
4.5/5
What do you like best about Synthflow?

I recently started using Synthflow to automate my inbound calls for my legal document business, and so far, I’m impressed. The platform is clean, intuitive, and really beginner-friendly especially for someone like me who doesn’t have an extensive tech background.

I was able to set up an AI receptionist in just a few steps. I love that it supports both English and Spanish, which is a huge plus for my client base. The drag-and-drop builder makes it easy to create custom flows, and I like that it can send texts with my booking link automatically.

There was a slight learning curve connecting Twilio, but the setup guidance and support options helped me figure it out pretty quickly. I also appreciate that they offer free minutes just for verifying my email and doing small tasks — it’s a great way to try it out without paying upfront.

Looking forward to seeing how it performs with real clients, but so far, Synthflow feels like a smart and affordable upgrade for small business owners. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

Nothing yet! It has been pretty easy to use so far! Looking forward to using it for my business. Review collected by and hosted on G2.com.

"Great voice AI platform for Custom Action integration"
4.5/5
What do you like best about Synthflow?

Easy to set up voice agents with professional voices. Custom Actions integration works well for connecting to external APIs. The conversation flow management is intuitive and the voice quality is excellent for business use cases. Review collected by and hosted on G2.com.

What do you dislike about Synthflow?

Chat simulator doesn't properly test Custom Actions - only works with actual phone calls, making development harder. Would be better if chat testing matched phone call behavior for faster iteration. Review collected by and hosted on G2.com.
