About Subtle
Subtle is an AI overlay for professionals who need real-time assistance during high-stakes moments — job interviews, sales calls, meetings, coding sessions, and presentations. The overlay is visible only to you and cannot be captured by any screen sharing or recording software. Subtle uses a BYOK (Bring Your Own Keys) model: you connect your own AI provider accounts, so your data never touches our servers. Available as a one-time purchase for macOS.
