Substack Content Translator with Gemini is a free Chrome extension designed to facilitate the translation of Substack content, specifically podcast transcriptions. As a beta version, users may encounter some bugs, but the tool aims to enhance accessibility for non-English speakers by providing translation services for Substack posts. Users can easily pin the extension icon and access it while viewing Substack podcast posts, ensuring a seamless translation experience.

To utilize the translation feature, users must input their own Gemini API key, which is necessary for the extension to function effectively. The tool currently supports translations for specific Substack posts, with the promise of expanding compatibility to additional sites in the future. This extension is a valuable resource for those looking to engage with a broader range of content on Substack.
