The quality of the agents and how simple it is to do an agent (if you have a paid account) Review collected by and hosted on G2.com. What do you dislike about Synthflow? I wasn’t able to start the promised 14 days agency free trial. It’s hard to try out as you don’t get credits to try it out as the free trial was not possible to be accessed. I was not able to contact a person easily to get help about all of this. Review collected by and hosted on G2.com. What problems is Synthflow solving and how is that benefiting you? I am starting a Ai assistant business, and I already had a client, but with no access to the promised free trial well, I guess that won’t work. Review collected by and hosted on G2.com.

Automation Consultant Small-Business (50 or fewer emp.) 8/2/2025 "Promising, but burdened by complexity and paywalls." 2.5/5 What do you like best about Synthflow? I like the customizability of the voice agents, including the modular system for creating knowledge bases and integrating other applications. Review collected by and hosted on G2.com. What do you dislike about Synthflow? The app was somewhat complicated to navigate. The voices for agents were not gendered, so trying to filter based on "male" or "female" in the dropdown filters yielded 0 results; moreover, there were no other filters, despite things like age and accent being obvious options for filters. I already opted to start a free trial, I already have a paid OpenAI API key, and I'm paying $1.50 per month for a number, but I can't even test out an agent BY MYSELF. This is EXTREMELY disappointing. I don't want to fill out this lengthy review for a few call-minutes just to see if I even like the tool. I should be allowed to have conversation with myself, free-of-charge. The membership trials are also rather lame. Two weeks only, then if I don't remember to cancel it in the event that it's not right for me, I'll be paying almost $500 dollars per month, minimum. Not only is it downright expensive, on its own, but it feels like you're trying to pigeonhole people into accidentally paying a large amount for the services. I'm literally trying to SELL your product to my clients as a part of my automation consulting business, and I can't test out the agent before committing to it personally or pitching it to my clients. You're hurting your own business! I'm not sure why, but the Zapier integration just doesn't seem to be fully functioning. The embed portion isn't loading. When I try to connect from the integrations page, I'm prompted to "install" Zapier--a fully online tool. The difference between "actions" and "workflows" seems unclear. Review collected by and hosted on G2.com. What problems is Synthflow solving and how is that benefiting you? I need an AI bot to handle phone-related work where a human otherwise would.

FD Francis Kwame D. Virtual Assistant Trainee Small-Business (50 or fewer emp.) 3/22/2026 "Clean Interface, But Still Early Days for Voice Agent Building" 2.5/5 What do you like best about Synthflow? Clean interface and easy to get started with building voice agents. Looking forward to testing it more.” Review collected by and hosted on G2.com. What do you dislike about Synthflow? Sometimes the setup can feel a bit unclear for first-time users, especially around testing and phone number configuration. Review collected by and hosted on G2.com. What problems is Synthflow solving and how is that benefiting you? Synthflow helps automate phone conversations and appointment booking, which saves time and ensures no customer calls are missed.

It saves us time and works reliably right out of the box. Review collected by and hosted on G2.com. What do you dislike about Synthflow? We only wish the AI calling assistant had more voice style options and slightly deeper customization, but overall it works very well. Review collected by and hosted on G2.com.

IT Technician Small-Business (50 or fewer emp.) 8/13/2025 "Efficient Flow Builder with Room to Grow." 2.5/5 What do you like best about Synthflow? User-friendly interface – The flow builder is drag-and-drop, so it’s quick to map ideas into working logic. Fast iteration – Changes are applied instantly, making testing and refining very efficient. Integrations – Works well with webhooks, APIs, and third-party tools, so it’s easy to plug into existing systems. Visual clarity – The node connections are clear, so even complex flows are easy to follow. Review collected by and hosted on G2.com. What do you dislike about Synthflow? Limited advanced logic options – Complex branching or conditional flows can feel restricted without workarounds. Documentation gaps – Some features are powerful but under-explained, requiring trial and error. Scaling complexity – Large projects can get visually crowded, and the interface doesn’t yet have strong organisation tools like grouping or collapsing nodes. Review collected by and hosted on G2.com. What problems is Synthflow solving and how is that benefiting you? Faster project delivery – I can build and launch flows in hours instead of days. Reduced technical dependency – No need to rely heavily on developers for logic changes. Improved workflow visibility – The visual layout makes it easy to spot errors and optimise paths.

JC Jonathan C. marketing Small-Business (50 or fewer emp.) 7/15/2025 "It´s very intuitive" 2.5/5 What do you like best about Synthflow? What I like best about Synthflow is how intuitive and easy to use the platform is. The drag-and-drop flow designer allows even non-technical users to build complex conversational AI agents in just a few minutes. The voices are surprisingly natural, and the multi-language support is a huge advantage for international teams. I also appreciate how quickly you can integrate Synthflow with other tools like CRMs or Google Calendar, and the ability to test and deploy new flows almost instantly. Overall, it dramatically reduces the time and resources needed to automate voice interactions with customers. Review collected by and hosted on G2.com. What do you dislike about Synthflow? Although Synthflow is a powerful tool, there are a few areas for improvement. Sometimes, creating advanced flows requires very specific prompt engineering, which may be a challenge for beginners. The pricing model can also be expensive for high-volume usage, especially if you need to maintain multiple numbers. Finally, while customer support is helpful, response times could be faster during critical issues. Despite these minor drawbacks, Synthflow is still one of the best voice AI solutions available. Review collected by and hosted on G2.com. What problems is Synthflow solving and how is that benefiting you? Synthflow is helping us automate and streamline our sales calls, allowing our team to qualify leads much faster and follow up with potential customers in real time. Before Synthflow, our sales team spent a lot of time on repetitive initial calls and data entry. Now, with the AI Sales Assistant, we can handle inbound and outbound calls automatically, schedule meetings, collect important information from prospects, and integrate everything directly into our CRM. This has improved our response times, reduced manual workload, and helped us increase conversion rates. Synthflow is especially valuable during peak periods when call volume is high, ensuring that no lead is left unattended and our team can focus on closing deals.

Additionally, the integrations with other tools work seamlessly and have significantly improved my productivity. Review collected by and hosted on G2.com. What do you dislike about Synthflow? Sometimes the performance is slow with complex tasks. I would also like it to have more predefined templates for specific use cases. The technical support, although friendly, can take time to respond to more technical queries. The initial learning curve was steeper than expected for advanced functions. Review collected by and hosted on G2.com. What problems is Synthflow solving and how is that benefiting you?
