Reach Agent

The Reach Agent is the front door. You ask one question in plain language. It works out which parts of the platform can answer it, runs them, and returns a single answer with the evidence trail intact.

This is the agent you are talking to in Gemini Enterprise. Everything else on this site describes what it does under that one conversation.

Ask it anything about your market or your catalog

Where are the gaps in my outdoor furniture catalog?

I'm launching insulated water bottles under $30. What does the landscape look like?

Which of my product titles would not show up for "best yarn for baby blankets"?

The second question spans four domains. You still ask it once.

How it answers

  1. It classifies the question by domain.
  2. It dispatches the skills that can answer it, in parallel when the question spans more than one.
  3. Each skill runs its own analysis against the graph and against your catalog when one is attached.
  4. It synthesizes the findings into one answer and appends the evidence.

The specialists stay named in the evidence footer. The star shows its work. You are never required to know which one owns which data.

What it needs from you

Nothing, to start. Without a catalog, it answers market questions: what buyers search, which categories are moving, what other stores sell and charge.

Attach a CSV and the same questions become about your products. See Upload your catalog.

Getting the most out of it

Name the thing. "Outdoor furniture" gives you an answer about outdoor furniture. "My catalog" gives you an answer about your catalog. Both work, and the narrower one is sharper.

Narrow after, not before. Ask the broad question, then cut it down with a follow-up. The conversation holds context, so "now just the ones under $40" works.

Scope with a group. After a catalog upload, tapping a product group puts the whole analysis on that group alone. Thirty-eight duvet covers give a better answer than 581 mixed products.
