AI points; it never writes. An AI model (Claude, by Anthropic) only selects sentences that already exist in your records. Every answer is a word-for-word quote, checked by fixed rules and by a second AI check, and nothing reaches your client until you approve it.

Customer record data flowQuestionnaires and records go from the browser to buy-web in Montréal, then the Console, storage, and the engine in Montréal, then back to the customer as a package. To check each question, only the relevant excerpts and the question text go to Anthropic’s Claude API in the United States. Email addresses go to SendGrid in the United States.

Customer questionnaires and records are stored in Montréal. To check each question, only the relevant excerpts and the question text, never whole files, go to Anthropic’s Claude API in the United States. Business email addresses go to SendGrid. Card and invoice data go to Stripe.
