Who wrote this comparison.
This page was written by OverFuture, a software company in Zaragoza that also builds AI chatbots. Because we compete in this market, we are not ranked; our details are in the ‘About us’ box. No company paid to appear. We checked every source again on 10 November 2026, and each fact below links to the page where you can check it yourself.

How we scored each company.
We include companies whose websites say they build or deploy AI chatbots, virtual assistants or conversational agents for other businesses. They may build them from scratch or on their own platform. Ready-made tools that anyone can subscribe to are covered in our chatbot comparison (in Spanish). An address anywhere in Spain counts.
| Criterion | Weight | How it is measured |
|---|---|---|
| AI chatbots for businesses as a stated service | 25 | The company’s own website |
| Verifiable address in Spain | 20 | Legal notice, privacy policy or terms |
| Track record | 20 | Year it states or, if none, the earliest reference to activity on its website. 20 points for 20 years or more, 15 for 10 to 19, 10 for 5 to 9, 5 for fewer and 0 if not stated |
| Chatbot case studies | 20 | Projects with their own page and a description. 20 points for two or more, 10 for one and 0 for none. A shared case page or a wall of logos does not count |
Public reviews (15 points) will join the January 2027 review, with their source and date. Until then the score is out of 85. Companies on the same score are listed alphabetically.
Sources and interest. We used each company’s website (legal notice, privacy, about and case pages), checked on 10 November 2026. OverFuture builds AI chatbots, so it is left out of the ranking.

How to choose a chatbot company.
- Start with the questions your customer service hears most often and the channel they arrive on.
- Ask which data the chatbot will answer from and what it does when it does not know.
- Ask for case studies with their own page and, if you can, try a chatbot already in use.
- Find out where conversations are stored and how the bot meets the GDPR.
- Check whether you are buying a custom build or a licence for their platform, and what happens if you stop paying.
