Types what you say on macOS, in Vietnamese and English at once.
The problem #
Dictation tools treat Vietnamese as a second language. They punish you for switching mid sentence, which is exactly how a Vietnamese developer talks: half the nouns are English, the grammar around them is not. So the tool that should save typing makes you retype.
The approach #
Hold a key, speak, release. The audio goes straight to a speech model tuned for code switching and the text lands in whatever app has focus, through the macOS accessibility layer rather than the clipboard. Two tiers, one fast and one accurate, because a Slack reply and a spec do not need the same model.
Where it is now #
Shipped. v0.3.10 released 2026-09-01, roughly twenty releases since June. Free while the model bill stays small; no paid plan has been turned on yet.
What happens if this works #
Speaking becomes a normal way to write software, not a novelty. The test is a Vietnamese engineer dictating a pull request description without once reaching for the keyboard to fix a word.
Evidence #
- 634 dictations from 9 users in one week, measured 2026-09-06
- 18 stars on GitHub, installed by 21 people on day one
- n/a, pre-revenue. First paid plan is gated on the model cost per user landing under $1 a month
