Frequently asked questions
What is RadLinguist?
RadLinguist is a minimalist AI companion for speaking and writing in a second language. It gives you instant correctness checks, translations, and natural phrasing alternatives without asking you to write a prompt.
How is RadLinguist different from a general AI chatbot?
General chatbots require you to craft a prompt before every question. RadLinguist replaces that with one-tap tools for the three things second-language users actually need day to day: is this correct, what is this in my language, and what are the alternatives?
Can I use my voice instead of typing?
Yes. Correctness and clarity checks work with either text or voice input, so you can use RadLinguist while speaking as well as while writing.
Who is RadLinguist for?
RadLinguist is built for immigrants and expats speaking and writing at work, students writing essays and practising fluency, professionals checking an important email before sending it, and bilingual families helping kids learn naturally.
Is there a web version of RadLinguist?
Yes. The RadLinguist web app is available at radlinguist.app and runs in your browser.
