CleverAI alternative: Voko and CleverAI compared (2026)

Who CleverAI is

CleverAI is based in Winkel (canton of Zurich). Its product, CleverAI Voice, is an AI phone assistant for small businesses, with a dedicated page for dental and medical practices. It is set up for you: you activate call forwarding and CleverAI configures the assistant from your website.

Voko (Bern) is a self-serve AI phone assistant: you set it up yourself, from your website.

Prices and contract

Three months at entry level (our arithmetic). Voko Starter: 3 x CHF 99 = CHF 297, no setup fee. CleverAI: 3 x CHF 249 = CHF 747, plus the setup fee, so CHF 1,237 with CHF 490 or CHF 1,497 with CHF 750. Live transfer is a paid CleverAI module (3 x CHF 99 = CHF 297 more). Voko Starter includes transfer to one number; several destinations come with Pro (CHF 299). CleverAI waives the setup fee if you leave within the 14 trial days.

Its home page and FAQ say “from CHF 490”, its dental page says CHF 750, and no page reconciles the two, so we show both. Its home page does not mention VAT; its dental page and terms say prices exclude it. Voko’s prices exclude VAT too.

Voko’s plans differ in features as well as minutes. Every plan answers, books into your calendar through Cal.com, emails a summary, handles opening hours and holidays, takes a message outside opening hours and has one transfer number. Pro adds appointment reminders, contacts with caller recognition and routing, several transfer destinations with a team directory, and bexio. Business adds the webhook and API, booking in your own system, number porting and priority support. The knowledge the assistant reads in full is capped at 40,000 characters on Starter, 100,000 on Pro and 200,000 on Business. CleverAI is a single plan without tiers, with live transfer as a paid module.

Where the flat rate pays off

CleverAI counts no minutes, so there is no per-minute price, only a break-even. The table below is our arithmetic: Voko Starter is CHF 99 plus CHF 0.35 for each minute above 500; Voko Pro is CHF 299 plus CHF 0.25 for each minute above 1,500. The extra-minute total is rounded up to the whole franc.

Up to 900 minutes a month, Voko Starter is cheaper (CHF 239 at 900 minutes against CHF 249; CHF 274 at 1,000). Above about 925 minutes, CleverAI’s flat rate wins and the gap widens, and Voko Pro costs more than CleverAI at every volume shown. With its transfer module, CleverAI’s line moves to CHF 348 (CHF 249 + CHF 99, our arithmetic). Against that, Voko Pro at CHF 299, which includes several transfer destinations, costs less up to about 1,690 minutes a month (CHF 324 at 1,600, CHF 349 at 1,700); Voko Starter, which includes one transfer number only, costs less up to 1,200 minutes (CHF 344). CleverAI’s fair-use clause names no threshold, so we cannot say where it starts to matter.

Feature by feature

Where CleverAI’s site is silent, the cell says so. That is not a “no”, so ask CleverAI.

Languages and Swiss German

CleverAI makes Swiss German its headline and its default. Voko offers it as a beta: the assistant speaks it, but how well it understands spoken dialect has not been measured. CleverAI publishes no measure either. On voices, pace and tone, CleverAI’s site gives no detail; Voko lets you set them.

Booking and calendar

CleverAI says direct calendar sync leads to double bookings, sync errors and unclear liability, so it sends an SMS link to the booking tool you already use. That is a considered choice, and it suits a practice with its own online booking. Voko books, but through Cal.com (every plan) or your own system (Business only), with one appointment type per assistant, and it moves only what it booked. For a business that wants the call to end with an appointment, Voko is the better fit.

Transfers, opening hours and voicemail

Outside hours, CleverAI’s transfer puts the call through to a person on standby. In hours it goes to reception if someone is there. It offers a callback first and never promotes the option. A dental on-call variant costs another CHF 99. From Pro you can set several transfer rules and destinations in the console; Starter has one transfer number. CleverAI’s stand-in contacts by weekday and time are a good fit for practices.

Contacts and caller memory

CleverAI argues that no memory means nothing to leak. Voko offers recognition, which you can switch off whenever you prefer. If your callers expect to be recognised, choose Voko from Pro; if the privacy of the call is the point, CleverAI’s stance is simpler.

Knowledge the assistant learns from

CleverAI does the first fill for you and, for practices, supplies a pre-filled starter pack developed with its clinical advisor. You then add details in an admin panel whose features its site does not describe. Voko publishes its sources and limits, and you maintain the content yourself.

Summaries, transcripts and recordings

This is the sharpest difference. With CleverAI, the only record of a call is the email in your inbox; it says the summary is discarded after sending. That is private, but it also means there is nothing to listen back to and no call log to search. With Voko you can review every call, and you decide what is kept and for how long.

Integrations, API and webhooks

CleverAI states no integrations apart from the SMS link to your booking tool. Voko has few native ones too: Cal.com on every plan, bexio from Pro, and the webhook and a booking interface for your own software (Business only). If you need a native Salesforce or HubSpot link, ask both providers.

Phone numbers

Team, security and support

Neither promises a service level, and CleverAI names neither ISO 27001 nor SOC 2 (Voko holds neither). CleverAI says it personally stands behind the service and offers a free appointment. Voko has roles and two-factor sign-in, which CleverAI does not mention. We found no “coming soon” item on CleverAI’s pages.

Data and privacy

CleverAI’s column is its own statement, not a check of ours.

CleverAI is open that its language and telephony providers sit partly in the United States, and says the phone number is not passed to the language model. Its site does not say where those providers process audio or text, or how long they keep it. Our data page lists ours and notes that voice and language processing run through US providers.

The trade-off is the one from the features: the less a service stores, the less you can review. Voko stores what you ask it to, and you can switch every part of it off. See also our data security page.

Setup and trial

CleverAI is done for you. Its site says the setup is personally guided and takes about 10 minutes of your time. You activate conditional call forwarding at your phone provider; CleverAI fills the assistant from your website. It claims you are ready within 24 hours, which we cannot verify. The trial lasts 14 days with the full feature set, transfer module included, and needs no card. No limit on calls is stated. Billing starts on day 15; if you leave before then, you pay neither the monthly fee nor the setup fee. Its terms add that the trial applies where it is offered, and that it turns into a paid subscription unless you cancel.

Voko is self-serve. You sign up, give your website, choose a language and a voice, and an assistant is built; the wizard says it takes about two minutes. A Swiss number is assigned, you test it with a call in the browser, then forward your calls. We make no go-live promise; help comes from written guides and a checklist in the console. The trial is 7 days or 30 minutes, whichever ends first, with no card, and it shows every feature except number porting.

• you want the assistant to book appointments in your calendar (every plan) and remind callers (from Pro);
• you want to listen to, search and export your calls, or recognise your regulars (from Pro);
• you take up to about 900 minutes a month and prefer to try it and set it up yourself.

Either way, listen to a real call before you sign. You can hear ours right now: enter your website, and an assistant that knows your business answers you. For all the providers side by side, read the 2026 comparison, and for the full arithmetic, how much an AI phone assistant costs.
