About

Chatterence answers from content the business has actually published, in over 30 languages, with a sub-second response time and an 86% resolution rate without human intervention. Behind it sits a BI layer that pulls in Google Ads, GA4, Meta Ads, and Search Console data alongside the assistant's own conversation logs, queryable in plain language instead of exported spreadsheets. Everything runs on isolated, EU-hosted infrastructure per client, GDPR and EU AI Act compliant by default, not retrofitted. Built by AC Agency (est. 1997, Las Palmas de Gran Canaria). Early access now, ahead of general availability.
