ClickUp owns the startup PM question, appearing first in every single answer across all 12 responses with a slot score of 97.
ClickUp is the only brand that achieved a perfect presence rate and an average position of 1, a combination no other tool came close to. Trello and Notion both appeared in nearly every answer but consistently landed around position 4, making them supporting characters rather than serious competitors for the top recommendation. The reasoning the assistants lean on is consistent: ClickUp's free tier is genuinely usable for small teams, and its consolidation of tasks, docs, and goals removes the need for multiple tools at a stage when startups can least afford tool sprawl. monday.com is the notable gap brand, showing up in Gemini's four answers but completely absent from ChatGPT's responses, which suggests its fit for early-stage startups is genuinely debated.

Slot score is position-weighted, 0 to 100: being recommended first counts far more than a trailing mention. "Appears in" is the share of answers naming the brand at all.
The main measurement above is the assistants' real answers with live web access. These rows show the same question on other surfaces: the models' bare memory, and Google's own AI search experiences.
ChatGPT, Perplexity, and Gemini each answered this question in two phrasings, several times each, with live web access and citations: the closest API-reachable version of the real assistant experience (no personalization or account memory, which no vendor can provide). Model-memory answers (no web) are measured separately and shown above as a comparison surface. A brand counts once per answer that recommends it. The exact questions:
