Gemini users can now track and split group expenses without paid apps like Splitwise. By providing detailed prompts—names, costs, currencies, and dates—the AI generates accurate tallies and analytics. For example, a user tracked a trip with five friends, logging expenses like RM150 for fuel and RM4,500 for a hotel. The tool even exports data to Google Docs, rivaling dedicated apps in functionality. While manual logging remains required for now, the process is streamlined via Gemini’s interface.

The rise of AI-driven tools like Gemini reflects a shift in how consumers manage shared finances. Unlike Splitwise, which requires subscriptions, Gemini leverages Google’s ecosystem, accessible on most Android and iOS devices. A key benefit is scalability—there’s no limit to daily entries, and complex splits (e.g., 65% payments) can be handled with specific instructions. However, the current version demands users input data manually, a limitation Google aims to address with agentic AI features planned for Gemini Spark. This update, teased at Google I/O 2026, could automate expense logging by integrating with other apps, acting as a virtual assistant for financial tasks.

Until Spark launches, Gemini remains a practical, free solution for group budgeting. Users must still enter each expense and participant manually, but the AI’s precision and export options make it superior to many paid apps. For frequent group travelers or event planners, this tool reduces friction in splitting costs. While not flawless, its ability to handle varied scenarios—like unequal contributions—positions it as a strong contender in the shared expense space. The real test will be whether Gemini Spark can replicate this efficiency without user intervention, a feature that could redefine how people manage group finances.
