↳ Common questions
Short answers.
Which sales tool do AI assistants recommend most?
Apollo is the sales tool AI answers name most this week: 37.3% of answers, ahead of Clay (30.2%) and HubSpot (23.1%).
Do ChatGPT and Google recommend the same sales tools?
Apollo leads in 4 of 5 engines; Apollo and Clay share the lead in Google AI Overviews. The share of answers naming Apollo ranges from 42.5% in ChatGPT to 29.9% in Google AI Overviews.
How often is the index updated?
Every week, with the same questions. Claude is measured every other week, and the comparison with the week before counts only the engines measured in both weeks. The date at the top shows the latest run, and the JSON file holds every week since 2026-10-21.
How does a sales tool show up more in AI answers?
Look at the sources column: each engine reads its own mix of vendor pages, third-party lists and forums. Being described accurately on the pages an engine already reads counts for more than publishing more on your own site.
↳ Method
How we measure.
80 questions written the way B2B buyers ask them (58 in English, 22 in Swedish): problems, categories, comparisons, alternatives, prices and how-to. Four engines are read from the live consumer products: ChatGPT, Google AI Overviews, Google AI Mode and Gemini, from the US for English questions and from Sweden for Swedish ones. Perplexity Sonar is asked through its API with web search on. Each answer is checked for 65 named sales and data tools. Shares count answers where the engine gave an AI answer. One run a week, so single-week moves of a few points are noise.
Disclosure: Revexa builds Leo, an AI agent in this category, and does not count itself in the index. Revexa was named in 9 of 384 answers this week.
