In August 2026, we analyzed 4,480 ChatGPT responses across 15 B2B software and platform categories to compile the EMARKETER AI Visibility Index. This index tracks how often brands are mentioned and how they rank against competitors. This is the first edition for B2B software and platforms, establishing the baseline against which we'll measure future shifts. This article showcases nine categories, but overall mention rates count recommendations across all 15 categories we track.

Microsoft led the leaderboard well ahead of Google. It appeared in 38% of recommendations, compared with 20% for No. 2 Google. Its lead over Google was larger than the spread between Google and No. 10 Intuit. Microsoft made the top five in five of the nine categories shown, ranking No.1 in three of them.

Microsoft's biggest category lead came in team communication software. It appeared in 85% of team communication software recommendations, 36 percentage points ahead of No. 2 Zoom, the largest gap between a leader and runner-up in the nine categories shown. Slack ranked No. 3.

Cloud infrastructure came down to three brands. Amazon Web Services appeared in 97% of cloud infrastructure recommendations, while Google and Microsoft both appeared in more than 80%. No. 4 DigitalOcean had a notably lower mention rate at 37%.

Project management software was the most contested category shown. Asana led with an 87% mention rate, followed by ClickUp (77%), monday.com (71%), and Atlassian (68%). Atlassian's mention rate was the highest of a No. 4 brand in any category shown.

About EMARKETER’s AI Visibility Index

Our AI Visibility Index is based on a structured analysis of ChatGPT and Gemini recommendations. Upcoming reports and articles will also include Google Gemini. Each query uses standardized prompts (e.g., “best CRM software provider” or “cloud infrastructure for AI workloads”) spanning product type, attributes, consumer needs, target audience, and price tier. Prompts are built with EMARKETER analysts and researchers and are validated with search volume, so every brand is measured against the same benchmark.
