For engineers, made by engineers
You've grinded the patterns. You know your complexities. But real interviews are a different beast — nerves, pressure, and a stranger watching every keystroke. Sotto sits invisibly on your screen, ready to offer a quiet nudge when your mind goes blank.

Not a crutch. A co-pilot — invisible to your interviewer, always in your corner.
📸
Capture the problem with one shortcut and get a clear breakdown — optimal approach, complexity trade-offs, edge cases — in your preferred language. Not to copy, but to confirm your instinct and get unstuck fast.
🎙
Transcribes the interviewer in real time with sub-second latency. When a follow-up question catches you off guard, hit "Ask AI →" to get a focused, context-aware response — so you can speak with confidence, not guesswork.

On macOS, Sotto is excluded from screen capture at the OS level. Zoom, Teams, and Google Meet see a blank window. Always-on-top, adjustable opacity, mouse pass-through — completely out of your way until you need it.

Interviewer's view
Excluded at the macOS OS level — not just minimized or transparent. Works on Zoom, Google Meet, and Teams.
A few habits that keep things natural and undetectable.
01
Never copy-paste — always type manually
Clipboard events are trackable and instantaneous code insertion looks unnatural. Type everything out character by character, even if it takes longer.
02
Be mindful of typing speed
Don't type too fast. Real engineers pause to think, backspace, and reconsider. A perfectly steady stream of correct code is a red flag in keystroke analytics.
03
Rewrite comments in your own voice
Don't copy AI-generated comments verbatim. Rephrase them in your own words and style — or skip them entirely if they feel out of place.
04
One-time setup before your first interview
Grant Sotto microphone, screen capture, and accessibility permissions in macOS System Settings. You'll only need to do this once.
05
Keep mouse pass-through on during the interview
Mouse pass-through (⌘⇧P) makes Sotto invisible to your mouse — clicks go straight through to the interview platform beneath it, so you never accidentally interact with Sotto mid-interview. All keyboard shortcuts (screenshots, transcription, opacity) keep working regardless. Only turn pass-through off briefly when you need to scroll or reposition Sotto, then turn it back on.
06
Use a single monitor
Keep Sotto and your interview platform on the same screen. Some platforms detect multiple monitors and flag the configuration as suspicious.
07
Position Sotto near the solution editor
Place the Sotto window close to the coding area before the interview starts. This way your eyes naturally look toward the problem — not off to the side of the screen.
08
Use device microphone, not system audio
Always record from your physical mic. If the interviewer's voice comes through headphones, Sotto won't capture it — the built-in microphone only hears what's in the room.
09
Think out loud during the interview
Narrate your reasoning even when reading Sotto's answer. Dead silence while code appears is suspicious. Talking through the problem makes your process look authentic.
10
Make small intentional mistakes
Occasionally mistype a variable name and correct it, or delete a line and rewrite it. Real developers make minor errors. A flawlessly clean keystroke stream is unnatural.
11
Consider avoiding transcription if asked to screen share
macOS shows a microphone recording indicator in the menu bar whenever an app is capturing audio. If you're sharing your screen, the interviewer might notice it. Use screenshot + Ask AI mode instead — no mic indicator, no questions.

Sotto is built for engineers who've put in the work — you've done the LeetCode, you understand the patterns, you know your complexities. But real interviews are stressful, and stress makes you second-guess yourself. Sotto is the friend sitting next to you who gives you a quiet nudge when your mind goes blank. It's not designed to carry you through an interview you're not prepared for — it's designed to make sure nerves don't tank one you are.
Yes — on macOS, Sotto excludes itself at the OS level. The window is excluded from all screen capture APIs, including Zoom, Google Meet, and Microsoft Teams. This works on both Apple Silicon and Intel Macs running macOS 12+.
It can do both, depending on what you need. If you're close but stuck on an edge case, glance at the approach hint and keep going. If you've blanked entirely, the full solution is there to orient you — you still have to reason through it out loud with your interviewer. Think of it less like autocomplete and more like having a knowledgeable friend on standby.
No. Screenshots are compressed and sent directly to an AI API for analysis — they are not stored on any Sotto server. Audio is streamed for transcription and is not retained.
macOS 12 Monterey or later. Both Apple Silicon (M1/M2/M3/M4) and Intel Macs are supported. The screen-sharing invisibility feature requires macOS 12+.
