Show HN: macOS Util for Deep Focus, Live Transcript and AskAI Anywhere (overlayai.app)

A new tool called Overlay has been launched, designed as an invisible AI assistant that enhances productivity during video calls and meetings. Notably, Overlay operates undetected on popular platforms like Google Meet and Zoom by injecting directly into the GPU stream, effectively bypassing screen capture software. This allows users to access powerful AI resources without revealing their assistance to others in the meeting. Key features include real-time meeting transcription, smart text selection, and OCR text extraction, which enables users to query non-selectable text from various sources, including images and PDFs. The significance of Overlay lies in its potential to revolutionize how individuals prepare for interviews, exams, or discussions by providing instant answers and context without distracting from the conversation. Its local-first design prioritizes privacy by ensuring that user data and API keys are kept secure and never leave the device, connecting directly to AI providers. With launch pricing offering substantial savings, Overlay presents an appealing option for those eager to integrate advanced AI capabilities seamlessly into their workflow while maintaining confidentiality and security.
