Outline: AI Visibility Report

When buyers ask ChatGPT, Claude, and Gemini about docs & knowledge management, Outline ranks #8 of 15, a Visibility Score of 13 in Docs & Knowledge Management .

These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.

How AI sees Outline

One category, one race, and Outline is losing it.

Where it wins. A 20.8% mention rate in Docs & Knowledge Management keeps Outline on the map, and feature-focused prompts are the one context where the models reliably surface it.

Where it loses. A 1.4% first-pick rate in a 15-tool field means buyers almost never land on Outline as the answer, and the models skip it entirely when the question shifts to enterprise fit, use-case specifics, or budget comparisons.
