Claude in Chrome and BiDi extension serve different automation roles in browsers

The BiDi extension, built by the developer, integrates with SeleniumVBA to handle WebDriver operations via WebSocket alongside HTTP. It excels at deterministic, repetitive tasks—such as downloading daily reports or bulk data entry—by letting users script exact elements and wait conditions. Unlike Claude, it integrates seamlessly with Excel VBA, enabling direct data input/output and compatibility with existing macros. Its design avoids fixed-duration waits, using Discovery Logs to track DOM changes and confirm task completion. The tool is ideal for environments where extension installation is restricted, as it runs self-contained in an .xlsm file. The developer combines both tools: using Claude for exploratory tasks and BiDi for routine automation, with AI assisting in analyzing logs to refine BiDi’s scripts.

Key differences include decision-making (AI-driven vs. scripted), Excel integration (native for BiDi, indirect for Claude), and environmental constraints (extension permissions vs. standalone VBA). The author emphasizes that the tools complement each other, with AI playing a role in both real-time operations and log-based optimization.
