macOS 14+ · Apple Silicon · speech recognised on-device
jhint listens to what your Mac is playing, turns it into text on the Neural Engine, and answers when you press Answer. You tell it what to do in plain words — translate, give background, draft a reply.
Before the session starts, describe in ordinary words what jhint should do with what it hears — or pick one of the built-in examples and edit it.
jhint takes the sound your Mac is playing — the other person's voice in a call, a recording, a video — and turns it into text locally, on the Apple Neural Engine.
Nothing is sent and nothing appears until you ask for it; then the answer arrives in the overlay in the shape you chose — Short, Standard, Detailed, or Code.
There are no modes to choose between. One field decides how jhint behaves for the rest of the session — these are the examples that ship with the app. Pick one to see what comes back.
The meeting is in English and it runs at full speed. You understand most of it, but you're always half a sentence behind — and by the time the reply is ready, the topic has moved.
Translate everything you receive into English, then suggest in one or two sentences how I could reply, in the language the other person is speaking.Someone drops a company name, a regulation, a term from a field next to yours. Everyone nods. You don't want to stop the call to ask, or search in another window while they're still speaking.
Give me background on the topics as they come up in this conversation: key facts, names and dates worth knowing, in a few short bullet points.There's one question you know is coming, and you've been answering it badly for weeks. Play back a recording, let jhint hear it, and read what it suggests — not a script, the two or three points you keep leaving out.
Suggest how I could answer what was just said. Give the key points, not a script.Privacy
jhint uses WhisperKit on the Apple Neural Engine. The audio itself is never uploaded anywhere — not to us, not to a model provider.
Recent conversation context, your profile, and exact figures are three separate switches, each off until you turn it on, each set per session.
What was said stays in the session and goes away with it, unless you choose otherwise.
No usage events, no crash pings, no analytics. Nothing is collected about how you work.
No answer is requested and nothing is sent until you press Answer — and while it's working, Cancel stops it.
jhint never sends audio into a conversation. It reads what your Mac plays and writes text on your screen, the way a notes app does.
Short, Standard, Detailed, or Code — set per request, so a reply is as long as you actually need.
Rules about recording, consent, and outside assistance vary by country, employer, and situation — and some settings, such as exams and proctored assessments, forbid this kind of help outright. jhint is not built for those, and we ask that you don't use it that way. Following the rules of the room you're in is your responsibility. Acceptable Use Policy.
On first launch jhint downloads the speech model — you'll see the progress in the overlay. After that it starts instantly, and the licence keeps working for three days without a network connection.
No. jhint doesn't send any audio into the call — it only reads the sound your Mac is playing, and answers appear as text in an overlay on your screen. It has no voice.
jhint works from your Mac's system audio — what you hear through your speakers or headphones. It is not built around recording your own microphone.
The audio never does — speech is recognised on your Mac. When you press Answer, the request goes to the model provider you've configured, and by default it contains only the current question. Recent context, your profile, and exact figures are added only if you switch them on.
Recognition keeps working, because it's local. Answers from an external provider need a connection. Your licence stays valid for 3 days offline, so a flight or a bad hotel network doesn't lock you out.
jhint listens to audio playing on your own Mac and doesn't store the transcript by default. But rules about recording, consent, and outside assistance vary by country, employer, and situation — and some contexts, such as exams and proctored assessments, forbid this kind of help outright. jhint is not for those. Following the rules of the room you're in is your responsibility.
No. jhint requires Apple Silicon and macOS 14 or later, because recognition runs on the Apple Neural Engine.
