I want to reply to English-speaking people on X and join the conversation in English. But my first language is Chinese, and my English isn’t great. I keep getting stuck while writing, so little by little, I’ve become less willing to say anything and more dependent on translation tools.

Do you ever feel the same way?

I made Graker because I wanted some help with this. I start by writing in English, then use a keyboard shortcut to check the grammar. It points out my grammar mistakes, spelling errors, and so on. That way, I get to learn a little English as I go, and feel more confident using it.

It shows the result right near the text field and lets me replace what I wrote. There’s another feature I find useful, too:

Sometimes, my first attempt in English doesn’t quite express what I had in mind in Chinese. After the grammar check, I can follow up with another sentence explaining what I meant, and have it adjust the result.

That’s the core of this little app.

BYOK

Bring your own AI API key. You choose the model and provider, which makes me feel a little more comfortable relying on it over time. Graker supports Google Gemini, DeepSeek, and custom OpenAI-compatible services.

Graker also has a translation feature. I often use it to quickly translate long passages in English so I can understand what they’re saying more easily.

It’s free, so if this is something you could use too, give it a try.
