Australia’s largest lender says Companion is an “agentic” assistant designed to help retail and business customers with practical tasks, including working out whether they can afford a new loan. The tool launches as OpenAI and Perplexity introduce similar assistants that use customer banking data to answer detailed financial questions.
CBA expects competition to intensify as everyday banking shifts away from branches and static app screens towards voice and chat-driven interactions. Executives at the bank describe the new assistant as the next front in digital banking, where the main relationship lives inside a smart assistant.
CBA is positioning Companion as both a service upgrade and a defensive moat against global technology platforms moving into core financial territory. The assistant is pitched as a way to streamline tasks that previously required manual calculations or branch conversations, such as affordability checks on new borrowing.
Rival platforms like OpenAI and Perplexity can potentially sit “on top” of multiple banks, letting customers compare products or run neutral analysis using data from several institutions at once. That creates a risk for lenders that their brand and app become less central if customers build habits around third-party AI tools instead.
Banking insiders say the emerging battle looks like a contest over who owns the customer interface, incumbent banks with embedded AI or global AI platforms that aggregate financial services. CBA’s leadership argues the native banking app will increasingly morph into a conversational, agent-based hub rather than a traditional menu of buttons and screens.
The strategic dilemma forces banks into an awkward dual role, needing to partner with AI giants to stay technically competitive while simultaneously treating them as direct rivals for customer attention. Banks are also watching how far global platforms will push into regulated banking activities and how aggressively incumbents like CBA can defend their ground.
