Bring the local question that needs your business context.
Name the Western Washington market and the work on your desk. Sentinel will build a precise first question and keep it in this browser for up to 24 hours. Continue here and Sentinel will answer it with your saved business context, supported local evidence, visible dates, and explicit verification boundaries.
The useful answer depends on the agent, the page, and the date.
Your business
Farm ZIPs, price band, client focus, brokerage, saved contacts, active deals, and the way you prefer to work.
Your current screen
The page, record, document, deal, or property you selected — plus the latest meaningful action you took on that item.
Supported evidence
Available county and public sources, source-dated market context, and deterministic WA math with unknowns kept visible.
Sentinel is not a substitute for NWMLS, your broker, an attorney, a CPA, an inspector, or field verification. It is the working layer that helps you assemble supported facts, calculations, open questions, and next actions.
Does Sentinel answer the question before signup?
This page builds the question without requiring a login and keeps the draft in this browser for up to 24 hours. Continue signup in the same browser to place it in chat. The standard continuation is a secure seven-day workspace; visitors who arrived through the Founding Agent Lab keep the 30-day offer shown on the page.
Which markets are supported?
Sentinel is focused on King, Snohomish, Pierce, and Whatcom counties. Source coverage varies by question and geography, so the answer identifies the source, effective period, and any verification gap.
Is this a general-purpose AI answer?
No. Sentinel combines the agent's configured business context with supported Western Washington sources and deterministic calculators. It labels assumptions and does not claim access to data it cannot retrieve.
