Integration details
Description
Stop re-explaining your business to AI every session. Nucleus gives Claude the facts about your business so its answers stop being generic. Add your website and documents. Nucleus turns them into one structured business context: identity, offer, pricing, ideal customer, positioning, brand voice, competitors, goals and the things you never want said. Where something is missing, it asks you targeted questions to fill the gap. Connect it to Claude and every chat starts from how your business actually works: • Get a one-call brief of who you are, what you sell and what never to say • Look up products, pricing, buyer personas and competitors by name • Search your curated sections and uploaded documents, with the source for every answer • Suggest updates when something changes. Every change is queued for your review, so nothing lands without your say-so Built for non-technical owner-operators. No technical setup: connect it, and your context stays maintained as the business changes. Nucleus is part of Second Team and is included in every Second Team plan. It is also available on its own.
