About PolyChat

PolyChat is a language learning product built by a small family team. We make conversation practice, free web games, a translator, and original guides for teen and adult learners.

Why we built it

We started PolyChat because most language apps stop at tap-the-right-word drills. People can recognize vocabulary and still freeze when they have to speak. Our work is about getting learners into real sentences faster: dialogues, speaking practice, and games they can repeat without an energy system getting in the way.

The website is part of that product, not a holding page. You can play games in the browser, translate phrases, read study guides, and see original research from PolyChat learners. The mobile app adds full lesson paths, custom lesson creation, and speaking practice.

Who PolyChat is for

PolyChat is designed for teens and adults — travelers, students, and professionals. Our website, playable games, and advertising are not directed at children under 13. If you are a parent and believe a child has used the product, email us and we will delete the account.

Advertising

We show Google ads in playable web experiences and the mobile app, usually as interstitials between sessions or as rewarded ads the user chooses to watch. We do not place ads inside blog articles. How that data is handled is explained in the Privacy Policy.
