Key takeaways
- The single most important criterion is whether the AI grounds its answers in your own content and admits when it does not know, instead of confidently making things up.
- Check the channels before anything else: a tool that only lives on your website is useless if most of your customers message you on WhatsApp.
- Where your data is hosted matters legally: EU hosting and a downloadable DPA make being GDPR-proof far simpler than a US-based tool.
- Pricing per workspace is predictable as your team grows, while per seat pricing punishes you for adding agents.
- Human handover and honest 'I do not know' answers are not weaknesses: they are what keeps customers trusting the bot.
Grounded answers versus a bot that guesses
This is the criterion that separates a useful AI customer service tool from a liability. A grounded bot answers only from sources you gave it: your website, your help articles, your product data. When it cannot find an answer, it says so honestly and offers to fetch a human, instead of inventing a return policy or a price that does not exist. A bot that hallucinates looks impressive in a demo and then quietly tells a customer the wrong delivery time, which is worse than no bot at all.
When you test a tool, deliberately ask it something that is not in your content and watch what it does. ovellan is built to answer only from your own content and to say 'I don't know' rather than guess, because an honest gap is recoverable but a confident wrong answer costs you trust. Insist on seeing this behaviour before you commit.
Channels: website and WhatsApp where your customers already are
A customer service tool is only as good as the places it can reach your customers. A chat widget on your website is the baseline, but in many European markets a large share of customers prefer to message on WhatsApp. If your tool cannot handle both, you are forcing customers into a channel they do not want, or you are running two disconnected systems. Look for one tool that answers on the website and on WhatsApp from the same brain and the same inbox.
ovellan answers on your website and via WhatsApp, and both feed into one shared inbox so your team never has to juggle tabs. WhatsApp does add a layer: it runs on the official WhatsApp Business Platform with its own approval and message rules, so factor a little extra setup in there compared to dropping a widget on your site.
Human handover, languages and everyday teamwork
No AI handles every conversation, and you do not want it to. The moment a question gets emotional, complex or high-value, the bot should hand off cleanly to a person with the full conversation history attached, so the customer never repeats themselves. A shared inbox where your team picks up these handovers, sees who is replying and can take over live is what turns an AI tool into real customer service rather than a novelty.
Language matters more than vendors admit. A tool trained mostly on English can sound stiff or subtly wrong in another language, which erodes trust fast. Test the bot in the exact language and tone your customers use. ovellan answers naturally in your customers' own language, whatever they use, with a shared inbox, live takeover, booking and order tracking built in so common requests get resolved without a human touching them.
Data, GDPR and where your tool is hosted
Customer service conversations are full of personal data: names, order numbers, addresses, sometimes complaints. Under the GDPR you are responsible for how that data is processed and where it lives. A tool hosted in the United States can still be used, but it drags in extra transfer safeguards and paperwork. A tool hosted inside the EU with a proper data processing agreement removes a whole category of legal headache.
Ask any vendor two blunt questions: where is the data physically stored, and can I download a signed DPA today. ovellan hosts in Germany (Hetzner), is built to be GDPR-proof and offers a downloadable DPA, so you can hand your compliance officer a clear answer instead of a shrug. Check the Autoriteit Persoonsgegevens and the European Commission guidance if you want the source rules yourself.
Pricing model, setup time and integrations
The sticker price matters less than the pricing model. Per seat pricing means every extra agent you add costs more, which quietly punishes you for growing your support team, exactly when you need it most. Per workspace pricing charges for the workspace, not the headcount, so your bill stays predictable whether two people or ten log into the inbox. Read the model carefully, because a low headline price with per seat billing can end up more expensive than a flat workspace fee.
Finally, weigh setup time and integrations honestly. Some tools need weeks of configuration and a consultant. ovellan uses per-workspace pricing, not per seat, and goes live in minutes with one line of code on your site, then improves as you feed it more content. Be realistic about integrations though: if you depend on a specific CRM or ticketing system, confirm that connection exists before you sign, because no tool integrates with everything and honesty here saves you a painful migration later.
