AI guidance, with sources. Confirm important decisions and availability with Mark. How Knox works
An open mind. An experienced foundation.
Less sales talk.
More perspective.
A move begins with questions. Ask yours in your own words, without a pitch or a form to fill in first.
What can I ask Knox?+
Explore KnokKnok’s published homes, understand a property’s details, think through a sale or prepare questions before making an offer. Knox can explain trade-offs and help organise your next steps. He cannot negotiate, submit an offer or book a viewing for you.
The experience behind the answers+
Mark Breffit’s career includes Knight Frank and Hamptons Private Office. Knox draws on Mark’s published approach, KnokKnok’s property particulars, area guides, seller advice and The Brief. This is a reference library used to answer questions, not a model trained on Mark’s private conversations or an independent search of the whole property market.
Meet the person behind KnokKnok ↗Facts, sources and a clear next step+
Open the sources beneath an answer to see the supporting pages. Published prices and commentary have dates and can change. Knox does not have a live feed of every sale, portal or private listing, and cannot provide a verified valuation. Personal legal, tax and mortgage decisions need current specialist advice.
Read The Brief ↗Your conversation and privacy+
When the AI service is available, OpenAI processes your question and recent messages to answer. Conversations are held in this page’s memory, not stored as a visitor profile, and clear when you leave or reload. Anonymous usage totals help us improve the service. If you choose to send an enquiry, the form explains what is saved. Avoid confidential information. Voice dictation uses your browser’s speech provider; it only starts when you press the microphone. AI access is limited, so Knox may offer published guides or a conversation with Mark instead.
