Sotto is a live conversation copilot built specifically for IT and enterprise professionals in job interviews — not another generic coding-interview tool. WHY SOTTO IS DIFFERENT Every other "AI interview copilot" on the App Store is built for software engineers answering LeetCode-style questions. Sotto is built for the world of enterprise IT: tenant migrations, identity governance, compliance frameworks, and the vocabulary that actually comes up in those interviews — M365, Entra ID, Intune, NIST, FISMA, ATO, CMMC, and more. HOW IT WORKS 1. Add your background. Your name, role, and a few lines about your real experience — Sotto answers as you, grounded in what you've actually done, not as a generic candidate. 2. Paste the job description. Before your interview, drop in the role you're interviewing for so Sotto's suggestions speak that role's exact priorities and terminology. 3. Just talk. Sotto listens live. When the interviewer pauses, a quiet suggested answer appears in your own voice — no typing, no tapping, nothing to fumble with mid-conversation. BUILT FOR PRIVACY Speech is transcribed entirely on-device using Apple's Speech framework. Your audio never leaves your device. Only the text of the conversation is sent to generate a response, and only when you ask for one. BUILT FOR IPAD Prop your iPad on a stand during a video interview and glance down when you need it. The split transcript-and-response layout is designed for exactly this — not squeezed onto a phone screen as an afterthought. WHO IT'S FOR IT systems engineers, cloud administrators, compliance and security professionals, and anyone interviewing for enterprise IT roles who wants a quiet second voice that actually understands the job. Sotto requires your own OpenAI API key, stored securely in your device's Keychain. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
