Zendesk leads the 'best Intercom alternative' question, appearing in every single answer across all three models with the highest slot score by a meaningful margin.
Zendesk is the only brand to hit 100% answer coverage and draws consistent mentions from ChatGPT, Gemini, and Perplexity across both question phrasings, averaging position 3 despite being a large-ticket enterprise product. Freshdesk and Help Scout each appear in 83% of answers but score 12 and 19 points lower respectively, with Freshdesk winning on cost framing and Help Scout on email-first simplicity. The slot is contested rather than owned, meaning Zendesk leads but holds nothing close to a lock — its 86 score and 12-point gap over Freshdesk leave real room for a focused challenger to chip away, particularly one that leans into the pricing-fatigue narrative that surfaces repeatedly in the actual answers.

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:
