Hermex is a Python tool that enables automation of ChatGPT and Gemini interactions through their free web interfaces, bypassing the need for official API keys or billing. It is designed for users who wish to script tasks such as running OCR on images, generating artwork, extracting text from screenshots, or asking questions, all without incurring per-token costs associated with the official APIs. The tool operates by opening a real Chrome browser session, simulating human actions to interact with the web UIs, sending messages, uploading files, and retrieving responses as Python objects.
Among its key features, Hermex supports uploading various file types—including images, PDFs, CSVs, and text files—directly through the web UI. It also allows users to download AI-generated images. To avoid bot detection, Hermex is built on undetected-chromedriver and simulates human typing behavior. The tool offers persistent sessions, so users can log in once and reuse the session for future automations. Its interface is designed to be fluent, supporting method chaining for more readable and maintainable scripts.
Hermex is suitable for developers and technical users looking to automate AI tasks via Python without dealing with API access limitations or costs. The platform does not require payment or subscriptions, as it leverages the free access provided by the web interfaces of ChatGPT and Gemini.
