What's Behind the Bot? The Tech Stacks Powering Australian AI Chat
Every chat widget loads code from somewhere, and that code is a fingerprint. By reading the scripts and embedded frames on ~500 Australian brand sites, we can see which platforms are actually running the country's customer-service chat — not what vendors claim, but what's live in production.
The vendor leaderboard
A handful of platforms carry most of the load. Zendesk is everywhere; the contact-centre heavyweights — Genesys, Salesforce and LivePerson — sit right behind it, and a long tail of specialist conversational-AI vendors fills in the rest.
Not all "chat" is AI
The leaderboard needs a health warning. Presence of a vendor doesn't prove a brand is using its AI features — and some of these tools aren't really customer-service AI at all. It helps to group them by what they actually are:
| Category | Vendors | What it means for AI |
|---|---|---|
| Contact-centre AI platforms | Genesys, LivePerson, Salesforce Einstein, Glia, Nuance, Cognigy, Ada, Yellow.ai | Built for conversational AI — strong AI signal |
| Help-desk / messaging (AI-capable) | Zendesk, Intercom, Freshchat, Gladly | Can run AI or human; AI is opt-in |
| Marketing / CRM chat | HubSpot, Drift | Often lead-gen, not support — weak AI signal |
| Pure human live-chat | LiveChat, tawk.to, Olark | No AI by default |
Zendesk topping the chart doesn't mean 63 AI bots. Zendesk runs everything from a fully automated answer-bot to a plain human ticket form. The same is true of HubSpot, which is frequently just a marketing chat box. Vendor presence is the start of the question, not the answer.
Build vs buy: the named bots
The brands that invested most didn't just switch on a widget — they built a named assistant on top of a platform (or several). The tech underneath Australia's best-known bots is a revealing mix of global AI engines and local engineering:
| Bot | Brand | Underlying tech |
|---|---|---|
| Codi | Telstra | IBM Watson + LivePerson |
| Red | Westpac | IBM Watson |
| Olive | Woolworths | Genesys + Google Dialogflow |
| Buddy | Bunnings | Salesforce |
| Ava | AAMI | Soul Machines (virtual human) |
| Q | Macquarie | In-house ("Macquarie Intelligence") |
| Ceba | Commonwealth Bank | In-house CBA AI |
| Virtual Assistant | NAB | In-house NLP + Khoros messaging |
Two stacks recur. The incumbent CX route — Genesys, Salesforce, LivePerson, with IBM Watson or Google Dialogflow doing the language work — powers most of the big-brand bots. And a build-it-ourselves route is emerging at the top end: CBA's Ceba and Macquarie's Q run on in-house AI, a sign the largest players now treat the assistant as core IP rather than a bought-in feature.
Where this is heading
The current stack is a generation behind the frontier: most of these bots are intent-and- routing systems, not large-language-model agents. The interesting shift to watch is the incumbents (Zendesk, Salesforce, Intercom, Genesys) bolting generative-AI tiers onto the exact widgets already deployed on these sites — which means a lot of Australia's "dumb" chat could become genuinely capable without a single new vendor logo appearing in our crawl.
