1st avg. position

+13 ahead of Freshdesk

Zendesk leads the self-serve help center question with a perfect appearance rate and the top average position across all three AI models.

Zendesk is the only brand mentioned in every one of the 12 answers, averaging position 1 across ChatGPT, Gemini, and Perplexity alike, giving it a slot score of 97 with a 13-point gap over the nearest rival. Freshdesk matches the 100% mention rate but consistently lands around position 3, making it the reliable second choice rather than a genuine threat at the top. The slot is contested rather than owned, meaning Zendesk leads on volume and position but has not cleared the weight threshold that would make this question decisively its territory. Any challenger aiming to displace Zendesk here would need to move up in average position, not just mention frequency, since Freshdesk's near-universal presence already shows that appearing in answers is table stakes.

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.

How this was measured

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:

• "What's the best customer support software for building a self-serve help center and knowledge base?"
• "We're answering the same ten questions forever and want customers to self-serve. Which customer support software should we use?"
