Best customer support software for live chat and chatbots

82/100 slot score
83% of answers name it
1st avg. position
+1 ahead of Tidio

Tidio leads on raw reach while Intercom wins on position, making this question a two-brand fight for live chat and AI chatbot shoppers.

Tidio is the only brand appearing in every single one of the 12 answers, but Intercom edges it on the slot score because the assistants consistently place Intercom first when naming an AI-first recommendation. Intercom's Fin agent is the reason cited most often: the answers point to its ability to resolve the majority of conversations without human handoff, a claim no other brand in the set attracts. Zendesk appears in 75% of answers yet consistently lands at position 2 or lower, functioning as a safe enterprise alternative rather than a lead pick. Comm100's appearances are concentrated entirely in Gemini, making its 25% share structurally narrow rather than broadly persuasive.

AI-generated analysis of the September 2026 measurements.

The full field

Every brand recommended for this question, from 12 answers across ChatGPT, Perplexity, and Gemini.

# Brand Slot score Appears in Avg. position
1 Intercom 82 83% 1st
2 Tidio 81 100% #3
3 Zendesk 67 75% #2
4 LiveChat 26 33% #4
5 Comm100 22 25% #3
6 Chatbase 20 33% #6
7 Freshchat 18 25% #4
8 Gorgias 17 25% #5

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:
