// the precise answer, the moment you need it

Sound like the sharpest person in the room.

Colleagues who always have the answer in the meeting. The student who knows every detail. The one interview question you blanked on. Fly on the Wall quietly listens to the conversation and hands you the exact answer — in an overlay only you can see.

on-device transcription · invisible on shared screens · macOS 15+

01 what it does

A second brain for live conversations.

It hears both sides, transcribes on your Mac, and surfaces the precise point you need — fast enough to use mid-sentence.

Meetings & standups

The metric, the name, the prior decision — recalled the instant it comes up, so you're never the one catching up.

Lectures & study

Definitions, derivations, the detail behind the detail — while the rest of the room is still nodding along.

Interviews

Concise, correct talking points for technical questions; runnable code for coding rounds, read straight off your screen.

Calls & negotiations

The follow-up question, the counter, the fact you'd have looked up if you had a spare minute.

02 how it works

Three steps. No fuss.

  1. Install & grant access. macOS 15+, Apple Silicon. Microphone, Speech, and Screen Recording — granted once.
  2. Paste your key. From the email you get at checkout, into the 👓 menu → Settings.
  3. Start listening. It transcribes on-device and feeds you answers in a panel that doesn't show up when you share your screen.

04 the stance

Precision, not cheating. It's the prep you'd have done with more time and the recall you wish you had — surfaced the moment it matters. Runs on your Mac; your audio isn't recorded or uploaded. Use it in line with the rules of any assessment you take part in.

05 questions
Is my audio recorded or uploaded?

No. Transcription runs on your Mac with Apple's on-device speech engine. Only the text needed to answer is sent to the model — never raw audio.

Is the overlay really hidden when I share my screen?

It uses macOS content protection, so it's excluded from the usual screen-share and recording paths (Zoom, Meet, Teams, QuickTime). It isn't guaranteed against every capture method.

How do I get my key?

Emailed automatically right after checkout. Paste it into the 👓 menu → Settings.

Can it help me prepare for interviews?

Yes — Fly on the Wall is built for interview prep and live interview support: it follows the conversation and surfaces concise, correct talking points (and runnable code for coding rounds), so you recall the right detail under pressure.

Does it work as a presentation or meeting assistant?

Yes. As a meeting assistant it recalls metrics, names, and prior decisions the instant they come up; as a presentation helper it feeds you the supporting detail and answers to questions from the room — all in a private overlay.

Is Fly on the Wall an interview-cheating tool?

We build it for preparation and precision, not deception — think of it as the research you'd have done with more time, recalled the moment you need it. Always use it within the rules of any interview, exam, or assessment you take part in.

“Can’t be opened” on first launch?
