About JERP

What JERP is

JERP is a free marketing AI tool. It scores homepage lists you already have — or pulls candidates from our homepage index — and returns structured judgments with confidence: real commercial offer or noise, fit to a category you name, how two sites relate, a rerank, or answers to your own yes/no, choice, and score questions.

It is built for marketers and agents working in Claude, Cursor, ChatGPT, and similar hosts over MCP or the REST API. JERP does not draft copy, report Google rankings, or measure how often a brand appears in chat answers. It cleans and judges the list so the model is not guessing from filler pages.

Who it is for

Use it when an agent would otherwise paste twenty homepages into a frontier model and ask it to “pick competitors.” JERP keeps that round trip small: you send domain, title, and summary (up to 24 cards on judgment calls); you get scores back. find and discover search the index; keep, fit, compare, rerank, and judge only score what you pass in. The free tier does not crawl arbitrary URLs on demand.

What we are not

JERP is not a crawl index like Ahrefs or Semrush, not a SERP tracker, and not legal, financial, or compliance advice. Index dates such as first-seen in the crawler are not company founding years. Read limits and tool semantics in the docs before you treat a score as a business fact.
