Slate Index

What it is.

Buyers ask an assistant for a shortlist before they ask a vendor. Slate Index counts which products get named in those answers and orders each category by the result, free to search, across 445 products in 28 categories.

Two ways to use it. If you're buying software, the category page is a shortlist with the supporting AI answers attached; if you sell it, your own page shows whether assistants name you when a buyer asks, and which sources they read to decide.

What you get.

  • Your position in your own category, with the AI answers behind it.
  • The sources assistants read to decide, which is where the work goes.
  • A shortlist with supporting evidence, if you are the one buying.
  • A weekly refresh, free to search, with no paid placement.
HOW TO USE IT

How to set it up.

1

Open your own category and read the order before you read your own position.

2

Check which sources appear behind the answers in your category, since those are the pages assistants read.

3

Compare your product page against the two products above you and note which sources they hold and you do not.

4

Recheck weekly and skip the daily look, because the index refreshes on a weekly schedule.

5

Treat a position change as a signal to check your source coverage, not as a score to report to a board.

Checking whether AI names you

Open your category and see whether a buyer asking an assistant would hear your product at all.

Building a buying shortlist

Finding source gaps

Questions about AI & Agents

Why does AI visibility matter for B2B software?
What moves how often an assistant names you?
Before you start
  • Your own category in mind, so you read the order before your position.
  • A browser, with no account needed to search.
Strengths
  • Free to search with no pay-to-play placement, and refreshed weekly.
  • 445 products across 28 categories, so most B2B software categories are represented.
  • The AI answers and their sources are shown, so a finding can be checked against the answer it came from.
Limitations
  • This is Slate's own index, and Slate sells the AEO software that acts on it, so read it as an interested party's data.
  • How often AI names a product is not a measure of product quality or market share.
  • Results move with model and prompt changes, so a weekly move may have nothing to do with your pages.
Skip this if
  • You already track your own answer-engine coverage weekly and act on the movement.
Ideal for
  • Product marketers
  • SEO and AEO leads
  • Founders
