NextAI Translator

Translate, polish or summarise any selected text using AI, in your browser or a desktop app.

What it does

NextAI Translator uses AI language models to translate text. Select words on a web page or in another app, and it translates them. It works across 55 languages.

Besides translation, it can polish your writing and summarise text. It can read text aloud, translate text from a screenshot, and keep vocabulary lists with memory aids for learning words.

It's available as a browser extension and as a desktop app for Windows, Mac and Linux. You need an account with an AI provider such as OpenAI, Azure OpenAI or MiniMax.

Who it's for

Language learners, readers of foreign-language content and anyone who writes in more than one language.

Can I use it without coding?

Yes. Download and install the app or extension; you need to add your own AI provider key. New to this? Start here.
