Voice notes
A thought with nothing to do stays a note. Notes are kept by day, and search finds them by the words you said. Every capture keeps its transcript and its recording: play it back, or find a task by words you spoke but never typed.
The recording and the words never leave the iPhone. There is no account, no server and no upload, which is also why deleting one is final: there is no copy anywhere else.
Audio stays on this iPhone and is kept until you delete it. If you prefer, set it to be deleted after a week, 30 days or a year, in Settings; the transcript is kept either way. Deleting an entry removes the note and its recording from the phone, and that cannot be undone.
Play a recording back from its note. The words you watch appear as you talk are the same words search reads later.
On 725 recordings of our own English to-do speech, the recogniser Offhand uses got about 95 words in 100 (a 5.3% word error rate); on 800 sentences of clean read speech, about 97 in 100 (3.3%). Both were decoded on a Mac on 30 August 2026. Numbers, dates, times, currency and spelled-out codes came through 60 times in 60. The full tables, with the corpora and the conditions, are on the blog.
