Need a Voiceflow alternative for voice on your SaaS website?

How do Voiceflow and Kawl Now compare?

Both can put a voice agent on your website. Voiceflow is a general agent builder for chat, phone and SMS, while Kawl Now does one job: a voice conversation in the visitor’s browser. We checked Voiceflow’s website and docs on 8 October 2026.

How does voice work in Voiceflow’s web widget?

You add Voiceflow’s widget by publishing your agent and copying a snippet from the Widget tab, and it can float, open as a popover or sit inside your page. Chat is the default modality, and three options add voice to it: dictation turns speech into text, voice output reads replies aloud, and voice mode lets people talk hands-free.

The voice modality goes further and makes the conversation behave like a phone call. Visitors don’t see the message history, can speak without pressing a button and can interrupt the agent, and the transcript is still saved. Voiceflow says voice features consume credits and that voice conversations in the widget can’t be recorded.

Approved domains, a legal disclaimer and turning off transcript saving need a Business or Enterprise workspace, and removing Voiceflow branding needs a Business plan.

Kawl Now’s widget is voice only. Visitors type what they need, allow the microphone and talk, with live captions, mute and an end button, after a notice that they are speaking with AI. It keeps a text transcript, records no audio and starts calls only on the origins you allow. The “Powered by Kawl Now” footer stays.

How do Voiceflow and Kawl Now handle knowledge?

Voiceflow’s knowledge base takes public web pages, sitemaps, PDF, TXT and DOCX files, CSV and XLSX tables, pasted text, and content from Zendesk and Shopify. Web and integration sources can refresh daily, weekly or monthly, metadata filters keep plans or regions apart, and Voiceflow says knowledge changes go live when you publish the environment.

With Kawl Now, your team approves each source on its own instead of publishing a whole environment. Support uses FAQs, notes and selected GitHub .md, .mdx or .txt files, and sales keeps its own notes. A new source does nothing until someone approves it, and every GitHub re-sync needs approval again. A workspace holds up to 100 sources of up to 50,000 characters each.

Voiceflow accepts far more formats. Kawl Now suits teams who keep product docs in GitHub and want a person to sign off each change before callers hear it.

How much of the agent do you build yourself?

Voiceflow gives you the parts of a custom agent: a global prompt, goal-based playbooks, step-by-step workflows, and tools that call APIs, functions, MCP servers or integrations such as Zendesk, Salesforce, HubSpot and Shopify. Environments let you test changes, split traffic for A/B tests and roll back. Its voice quick start can also generate the global prompt from a description, so a first agent needs no playbooks or workflows.

Kawl Now starts every workspace with a support agent and a sales agent. For each one you set a greeting and instructions, pick Marin or Cedar as the voice, approve knowledge and add your site’s HTTPS address. Test it in the dashboard, then switch on customer calls. There are no flows or custom tools to design, and no CRM or calendar actions.

Can callers use a phone line or reach a person?

Voiceflow can do both. You connect numbers from Twilio, Vonage or Telnyx, or let Voiceflow provision a US or Canadian number, for inbound and outbound calls, and Twilio numbers can also handle SMS. On phone projects, the call forward step transfers a caller to another number, and the live agent handoff step passes conversations to Genesys, Ujet, Kustomer, Dixa or Zendesk.

Kawl Now runs every conversation in the visitor’s browser, with no phone number for customers to call. Its human handover is an early release: once your team verifies a UK or US phone number and turns handover on, a caller can choose Talk to a human, and your team hears a private briefing before the caller is connected. Customer routing is still being tested, so keep your usual contact options on the page. With handover off, when approved sources don’t cover a question, the agent is told to say so and point callers to those options.

What do Voiceflow and Kawl Now cost to start?

On 8 October 2026, Voiceflow’s pricing page offered agencies a free trial and asked businesses to book a demo, without listing plan prices. Its docs describe a monthly plan fee, add-ons and usage credits, with plan prices shown inside the app. The Free plan’s credits don’t renew, and the self-serve credits table lists $0.005 a message and $0.05 a phone minute, plus model and speech usage.

Kawl Now gives each workspace its first 50 conversations free, shared by support, sales and dashboard tests, and each call lasts up to 10 minutes. Paid calls aren’t available yet, so no payment is collected and new calls stop once the allowance is used.

Should you choose Voiceflow, Kawl Now or both?

Start from what your customers need, then test each option with the same real questions.

• Choose Voiceflow to design custom agents with workflows and tools, serve chat, phone and SMS from one platform, hand conversations to a contact centre, or connect Zendesk, Salesforce, HubSpot or Shopify.
• Choose Kawl Now to let visitors talk through setup, feature and pricing questions in the browser, with separate support and sales agents that search only approved sources.
• Use both, with Voiceflow’s chat widget for typing and Kawl Now for speaking. Put the Voiceflow widget on the left, because the Kawl Now button sits bottom right, and test both before you switch on customer calls.
