Dictation that keeps up

Long dictation in Mandarin, Cantonese and English. Use your own AI provider's key, Zizai AI with no key at all, or recognition that runs entirely on the phone.

Fix the character, not the sentence

Speech recognition often picks the right sound but the wrong character: 在 for 再, 他 for 她. Tap 改 and step through the characters that sound the same, ranked by the words around them.

AI cards

One tap to fix grammar, polish the wording or translate, in the language you choose. Add your own cards for the prompts you use every day.

Pinyin, Jyutping and real keyboards

Full Pinyin typing, Simplified or Traditional output, and Cantonese. Pair a Bluetooth keyboard and the shortcuts work there too.

What stays on your phone

Zizai doesn't log what you type and has no ads or analytics. Your dictation history, prompts and keys stay on the device. If you use Zizai AI, the text of the card you tap passes through our server to Groq and is not stored. The privacy policy has the details, and the source code is public.
