Core concepts

Most questions about Vendlen turn out to be questions about one of four things: what context a decision was allowed to see, how wide its scope was, how far back it looked, and what the output actually claims.

Read these in order the first time. Every other section of this documentation links back here rather than explaining them again.

Context

• Product Line — the category-level working context Vendlen builds from your account.
• Product Group — ASINs that share one meaningful keyword set, read as a single body of evidence.

Scope and evidence

• Decision scope — Individual ASIN or Product Group, and what changes between them.
• Data Window — how far back a rule may look, and what sets the ceiling.
• Evidence and periods — why the same target reads differently depending on how time is cut.

Output and control

• Decision Brief — the anatomy of what the AI Analyst writes.

Reference

• Glossary — every term used in the App and in this documentation.
