iPhone
Turn speech into text and tidy punctuation and spoken corrections on your iPhone. Voice and dictated text are not sent to a cloud inference service.
ONIVO turns your speech into text and tidies the wording. Use it in notes, messages and other fields that support custom keyboards.
Speech recognition and AI text cleanup run on your iPhone. Cleanup is designed to preserve questions as dictated text, without answering them. Choose Speed priority or Accuracy priority for text cleanup. Results may contain errors; review them before sending or sharing.
System default is the initial speech recognition choice. Fast (Japanese), Fast (English/Europe) and Accuracy focus (Multilingual) options remain available. Speech-language coverage varies by method. System recognition requires a supported device and language with iOS 26 or later, and initially follows your iPhone’s preferred language.
Before first use, download and prepare the required data and add the keyboard. Initial preparation may take time. To dictate, open ONIVO, turn on Active session, return to your input app and select the ONIVO keyboard. The microphone remains active during the session, with the iOS microphone indicator visible.
Basic keys work without Full Access. Dictation requires Full Access for local communication between the app and keyboard. Custom keyboards are unavailable in secure fields and apps that disable them. If ONIVO can no longer verify the input destination, results remain available for review and manual insertion.

Updated text cleanup with AI trained for dictation, focusing on spoken corrections and unnecessary fillers. Improved formatting of numbers, dates and phone-number digit sequences.
Added speech detection to the accuracy-focused recognition option to reduce unwanted text from silence and noise. Clarified recognition choices and kept the ONIVO screen awake during model download and preparation.
