FlexiVoice (Smart AI Invoice Parser)

English | 中文

FlexiVoice is an intelligent invoice processing tool designed specifically for finance and administrative personnel without a technical background. It completely revolutionizes the tedious traditional process of manual data entry, making advanced AI technology accessible to everyone.

The most significant feature of this application is its extremely lightweight, pure front-end architecture. Users do not need to install any software or rely on a back-end server. All data processing and AI calls are securely completed within the user's local browser, ensuring data privacy and providing an "out-of-the-box" user experience. At its core is a powerful multi-modal large language model that can "read" and understand various invoices just like a human. Whether it's a standard electronic PDF or a scanned image of an invoice from a phone, the system can achieve high-precision extraction of key information.
