Key takeaways
- An AI receptionist is voice on the phone; an AI chatbot is written contact on web and WhatsApp. They are different channels, not competitors for the same slot.
- Voice fits phone-first, appointment-driven work where callers expect to talk; written AI fits async questions, order status and after-hours contact.
- Chat and WhatsApp leave a written record, are easier to hand to a human, and generally cost less to run than live voice.
- ovellan does chat and WhatsApp, not phone calls; it answers from your own content and says "I don't know" instead of guessing.
- Both channels touch personal data, so under GDPR and the EU AI Act you need transparency and a clear route to a human.
What each one actually is
An AI receptionist (or AI telefoniste) is voice technology. It picks up the phone, converts the caller's speech to text, works out what they want, and speaks a reply back in a synthetic voice. It lives entirely in the moment of the call: no queue, no waiting for an agent, just an immediate spoken answer or a transfer.
An AI chatbot is written contact. It answers typed questions in a widget on your website or in a WhatsApp thread, and the conversation stays on the screen as text. ovellan is this second kind: it answers from your own content, hands over to a human in a shared inbox when needed, and handles things like booking and order tracking, all in writing. It does not make or take phone calls.
When an AI receptionist is the right call
Voice wins when the phone is genuinely where your customers are. Think of a dental or physio practice, a garage, a restaurant taking reservations, or a trade business where people call while their hands are full. For these, a caller expects to speak, hates typing, and often wants one thing done fast: book, cancel, or reach a person. A good voice AI can catch the overflow calls that would otherwise ring out, take a message after hours, and route the rest.
Be honest about the trade-offs though. Voice is harder to get right: accents, background noise and interruptions all trip it up, and a misheard word in speech is more jarring than a typo in chat. It usually costs more per conversation because live audio is expensive to process, and there is no written trail unless you record and transcribe, which itself raises privacy questions.
When chat and WhatsApp win
Written AI wins whenever a conversation does not need to happen in real time. Someone checking their order status at 23:00, asking about opening hours, comparing two products, or sending a photo of a broken part does not want to phone; they want to type, get an answer, and get on with their evening. Chat and WhatsApp are async by nature, so a question asked at midnight gets answered at midnight without a single person being awake.
Written channels also carry practical advantages. Every conversation is a record you can search, so nothing gets lost in a phone note. Handing a tricky case to a human is seamless: the whole thread is right there in a shared inbox. Links, order numbers, addresses and photos all travel cleanly as text, where over the phone they get spelled out letter by letter. And WhatsApp meets a huge share of customers on the app they already use every day.
Where ovellan fits, and where it does not
ovellan is deliberately a chat and WhatsApp AI, not a phone bot. It answers from your own content, your pages, FAQs and documents, and when it does not know, it says "I don't know" and offers a human instead of inventing an answer. You add it to a site with one line of code and can be live in minutes, it shares one inbox with your team, and it handles booking and order tracking in writing. Pricing is per workspace, not per seat, so growing your team does not grow the bill.
It is also EU-hosted (Hetzner, Germany), GDPR-proof, and ships with a downloadable data processing agreement (DPA), which matters when the conversations touch personal data. If your business truly lives on the phone, pair ovellan for written contact with a dedicated voice product; the two channels complement each other rather than compete. But if your customers already reach for the website or WhatsApp, a chat AI covers the bulk of contact at a lower cost and with a cleaner paper trail.
Rules that apply to both channels
Whichever you pick, the same law applies. Both voice and chat process personal data the moment a customer shares a name, phone number or order detail, so GDPR requires that you are transparent about it, collect only what you need, and keep it secure. The Autoriteit Persoonsgegevens is clear that automated processing does not lower that bar; if anything it raises the need to be open about what happens to the data.
The EU AI Act adds a transparency duty: people should be able to tell they are talking to a system, not a person. In practice that means saying up front that it is AI, whether the reply comes as a voice or as text, and always offering a clear route to a human. ovellan is built around exactly that: it is honest about its limits and hands over cleanly, which keeps you on the right side of both GDPR and the AI Act.
