About FluentSide

FluentSide is a language-learning companion for people who already write in ChatGPT every day. Instead of adding another app or exercise routine, it turns the corrections ChatGPT gives you into a private record of the mistakes you actually make.

Why it exists

Many people write in a second language every day: emails, messages, documents. ChatGPT already fixes those sentences, but the corrections disappear with the chat. FluentSide keeps them, groups them by type of mistake and shows you what keeps coming back, so you know what to practice.

How it works

You connect FluentSide to ChatGPT as a connector and choose the languages you are improving. When your message contains a mistake, ChatGPT answers normally and then adds a short correction. With your consent, only that sentence, its correction and the explanation are saved to your account. On fluentside.com you see your recurring mistakes, your progress over time and suggested lessons and videos.

What we stand for

  • Privacy first: your full conversations, ChatGPT's answers and the sentences you wrote correctly are never stored.
  • Honest progress: numbers come only from your saved corrections. There are no invented scores, and levels are self-reported, not certified.
  • Curated, not generated: lessons come from a reviewed catalog of external websites and videos, never invented links.
  • You stay in control: pause collection, disconnect ChatGPT or delete your data at any time.
