Can CodexFan correct my writing and grammar?

A fixer for what you write

Writing in a new language is one of the best ways to notice the gaps in your grammar, but only if someone points out what to fix. CodexFan's Writing Fixer does that for you: you write or paste a sentence, a message or a short paragraph, and it checks the spelling and grammar and suggests corrections.

Why it helps you learn

• Immediate feedback — you see the fix while the sentence is still fresh in your mind.
• Real writing, not exercises — correct the messages and texts you actually want to send.
• Fewer repeated mistakes — seeing the same correction a few times helps the rule stick.
• More confidence — you can send a message knowing the grammar has been checked.

Part of a bigger toolkit

The Writing Fixer works well with CodexFan's Grammar Course and Grammar Patterns when you want to understand the rule behind a correction, not just apply it. And because CodexFan is built for conversation, you can put your cleaner writing to work chatting with native speakers or the AI language partner. A good habit is to draft a message, run it through the Writing Fixer, and note any correction that surprises you — those are the rules worth studying next. It is free to start and works on iPhone, iPad, Mac, Android and Windows.
