A Synthflow alternative with a price you can see before you sign

Consider UIRIX AI instead of Synthflow if you are a small or mid-size business that wants a published monthly price (from $49) rather than an enterprise contract, which Synthflow's pricing page lists from $30,000 a year. UIRIX builds the agent from your website URL, answers calls, runs outbound campaigns and adds chat and voice widgets to your site.

When Synthflow is the better choice

Synthflow has moved decisively upmarket. Its pricing page describes custom-scoped enterprise contracts starting at $30,000 a year, with SLAs, implementation support and forward-deployed engineers. If you run a contact center, a BPO or a large support operation, that model can make sense: you get a vendor that helps design, test and launch the agents with you.

Synthflow is also the stronger pick when your security team requires formal certifications. Its site lists SOC 2, HIPAA, PCI DSS, GDPR and ISO 27001, plus EU and US hosting options. UIRIX AI is a smaller, newer company and does not hold these certifications today, so regulated healthcare or payments teams should weigh that honestly.

• You need to plug voice agents into an enterprise PBX such as Cisco, Avaya or Genesys, or bring your own carrier over SIP.
• You want a very large integration catalog (Synthflow lists 200+ integrations, including Salesforce).
• You handle high call volumes and prefer a negotiated contract with an SLA over a self-serve plan.

When UIRIX AI fits better

UIRIX AI is aimed at owners and small teams who want to start without a sales call. You paste your website address, the agent reads your pages and drafts its own knowledge, greeting and instructions, and you can test it the same day. There are no setup fees, and the trial credit needs no credit card.

One agent covers several channels at once: inbound calls, outbound calling campaigns, a chat widget and a voice-in-browser widget for your website, and a demo page that shows the agent on top of your own site. That makes it easy to show the result to a partner or a client before you connect a real phone number.

• Published plans: Starter $49/month (1 agent, about 100 inbound and 100 outbound calls included), Pro $99/month (3 agents), Business $299/month (10 agents).
• Pay-as-you-go option: $10 to start, then a prepaid wallet (first deposit $100) for usage beyond the plan.
• 21 inbound actions, including leads, support tickets, orders, callbacks, appointments in Google Calendar or Microsoft 365, and live transfer to a person.

How to switch from Synthflow

Start by exporting the prompts, FAQs and call flows you already wrote in Synthflow. In UIRIX you can upload PDF or DOCX files next to your website crawl, and mark a document "keep as is" when the agent must quote it word for word, such as a cancellation policy or a price list.

Run both agents side by side for a week: forward a secondary number to UIRIX, compare the transcripts and post-call summary e-mails, and move your main number over only when you are happy with the answers.
