Yanxu AI — Proofread, Translate & Polish

Connect your own LLM to proofread, translate, and polish text right in your browser.

Yanxu AI is a focused writing assistant for your browser. Connect an OpenAI-compatible Chat Completions service you trust and improve text without breaking your flow. - Proofread and complete: fix spelling, grammar, and word choice, then finish incomplete thoughts naturally. - Translate: detect the source language automatically or choose the language pair yourself. - Polish: preserve the meaning while making sentences clearer, smoother, and more professional. - Popup options: compare three approaches and copy any result with one click. - Inline suggestions: enable and authorize access to mark issues during typing pauses. Click a mark to accept one minimal correction; unfinished text may receive one completion. Accepting a suggestion does not trigger repeated rewriting. - Saved draft: your latest input stays on this device and returns after closing the popup or restarting the browser. Clear the input to delete it. - Read from the page: only when you ask, use selected text or the currently focused text field. - Quick access: set a keyboard shortcut to open or close the popup and focus the editor instantly. - Multilingual interface: available in Simplified Chinese, Traditional Chinese, English, Japanese, and Korean. Settings, API keys, and your latest input draft remain on this device without Chrome sync. Text goes directly to your configured model service when you generate, or during typing pauses after you enable and authorize inline suggestions. Model results are not saved persistently. The publisher operates no relay server and includes no ads, analytics, or tracking.
