ChatterLab

ChatterLab is an AI chatbot platform that trains a custom support chatbot on your docs, websites, and knowledge base and deploys it as a branded widget in minutes. You point it at your content, and it produces an assistant you embed as a widget or iframe; each answer carries source citations with a confidence score, so users and your team can see where a reply came from. Its distinguishing angle is data residency: infrastructure is EU-hosted with EU AI Act compliance built in, which matters for European businesses and for agencies managing client agents under GDPR. Custom branding is available on every plan, and the 'Powered by ChatterLab' badge can be removed through an add-on. Higher tiers add API and MCP access, while contact collection and ticket management start at the Starter plan, so the chatbot can hand off leads and support cases rather than just answer questions. For a BestAIFor shortlist of the best AI chatbot for EU-compliant support, ChatterLab's pitch is clear: it is a documentation-trained support bot with transparent citations and European data residency, priced from a free tier up through agency and enterprise plans.
