Immersive Translate is an AI translation tool designed around reading and watching, not just pasting text. Its best-known feature is bilingual website translation: it shows the original and the translation side by side in a vertical layout, which makes it easier to compare meaning and learn a language as you read. It runs as a browser extension on Chrome, Edge, Firefox and Safari, and also as mobile apps for iOS and Android.
Beyond web pages, the tool covers documents, video and images. It translates PDF, ePub, HTML, TXT, DOCX, Markdown and subtitle files while preserving the original layout, and can OCR scanned PDFs so they become searchable and translatable. For video, it generates real-time bilingual subtitles on more than 100 platforms, including YouTube, Netflix and Prime Video, and can even translate videos that have no original subtitles. It also handles image and comic translation and adds live translation to online meetings on Zoom, Google Meet and Microsoft Teams.
Under the hood, Immersive Translate integrates more than 20 translation engines, among them ChatGPT (OpenAI), DeepL, DeepSeek and Gemini, and supports over 100 language pairs. Context-aware AI terminology libraries and customizable glossaries help keep names, technical terms and jargon consistent, which matters for academic papers, contracts and technical documentation. According to the project, the extension is used by more than 30 million people.
