Natively is a desktop application for macOS and Windows. It sits beside a live conversation — an interview, a client call, a lecture, a standup — transcribes both sides of it, and puts an answer on your screen when you ask for one. It is not a meeting bot: nothing joins the call, and no other participant sees a new attendee appear in the roster.
The three things it does at once
- Listens. System audio and your microphone are captured as two separate channels, so the app knows who said what. The capture pipeline is written in Rust and hands raw PCM to the app layer without a copy, which is why it stays under half a second behind the room.
- Sees. One shortcut screenshots the region of your screen holding a coding problem or a slide, runs OCR over it, and feeds the extracted text into the same context as the transcript.
- Answers. The reply renders inside a floating overlay that Zoom, Google Meet and Microsoft Teams do not include in a screen share.
Where your data lives
Audio capture, transcription buffering and the transcript archive are all on your own machine. Transcripts are embedded into a local SQLite database with sqlite-vec, which is what makes it possible to ask what did the VP say about the migration three weeks ago and get the exact chunk back. That database is a file on your disk; it is not synced anywhere.
Nine modes, not nine prompts
The mode you pick rewrites the instruction set behind the request rather than prepending a suggestion to it. Technical Interview mode forces every answer into problem statement, approach, edge cases, complexity and follow-ups. Sales mode tracks objections and discovery. Lecture mode formats formulas. The difference matters in practice: a mode-shaped answer is one you can read aloud, and a suggestion-shaped one usually isn't.
What it is not
- It is not a note-taker bot. Nothing appears in the participant list, and there is no recording notice to dismiss.
- It is not a chat window you alt-tab to. Alt-tabbing is visible; the overlay is not.
- It is not a guarantee against every proctoring system. Stealth covers screen-share capture and process names — it does not cover a proctor watching you through a webcam, or a locked-down browser on a second machine.
