Support chatbot that answers from company documents

Price lists, datasheets, warranty terms and subsidy guides in one chat. Every answer shows its source, and the bot says “I don’t know” instead of guessing.

The problem

What it solves

Installers answer the same questions every day: which heat pump size, what the warranty covers, whether a house qualifies for a subsidy. The answers are already written down, in PDFs and on the website, but nobody finds them fast.

The tricky part

What had to be right

Numbers. A wrong kW rating or warranty term is worse than no answer. Every reply has to quote a sentence from the retrieved documents; figures that aren’t in the sources are blocked and the bot hands over instead.

Inside

What it does

  • Chat widget for the website that replies in the visitor’s language
  • Answers only from company documents, with document and page shown as the source
  • “I don’t know” plus a handover form (name, phone, consent) straight into the CRM
  • Quick actions: book a survey, prices, subsidies
  • Admin: upload PDF, DOCX or URL, daily website sync, status of every document
  • “Unanswered” list, so the team sees which document to add next

What the owner gets

Fewer repeat questions for the engineers, and leads that arrive with the question already asked.
