In a chat, a learner types a Chinese sentence that ends in English, opens didao, picks a suggestion shown with pinyin, and sees the sentence confirmed as natural.
In the app, a learner looks up a Chinese phrase, sees a suggested correction with pinyin, then asks didao and hears that the new sentence sounds natural.

A few things to know
Won’t this just make me depend on it?
didao only fills the part you couldn’t write, and shows you what it chose, with pinyin and meaning a tap away. Phrases you save come back for quick recall practice, so the goal is needing it less over time.
Does it read everything I type?
No. Nothing is sent until you tap for help, and then only the text needed for that request goes to the model provider. Your saved expressions and learning history stay on your device unless you export them.
Will it sound like a textbook instead of me?
It keeps your Chinese and your tone. Style settings (casual to polished, how much slang, how direct) shape suggestions, and when your sentence already works, didao says so instead of changing it.
Do I have to switch keyboards or change apps?
Keep writing in your usual keyboard and switch to didao only when you’re stuck. Insert the suggestion, and you’re back in the same conversation.
When can I get it, and what will it cost?
didao is in testing and not publicly available yet. When the early-access list opens at the top of this page, join it and you’ll hear first, including pricing, before anything is charged.
