BOB is a transparent desktop AI overlay built for people who don’t want to constantly switch tabs just to use AI.Instead of opening a browser, pasting screenshots, or typing prompts into another window, Bob stays on top of your screen and works directly inside your workflow. It can analyze screenshots, answer coding questions, generate interview Q&amp;A, stream live AI responses, and even handle voice conversations in real time.The overlay is click-through by default, meaning it doesn’t interrupt whatever you’re doing underneath it. You can hide/show it instantly with global shortcuts, move it around your screen, lock interactions when needed, and switch AI models on the fly.Core features: → Screenshot analysis with real-time streaming responses → Live voice AI conversations using Gemini Live → Transparent always-on-top overlay → Smart click-through system → Global keyboard shortcuts → AI-generated interview prep notes → Markdown + syntax highlighted responses → Configurable coding preferences (language/framework/style) → Notes panel for quick reference during work/interviews → Persistent sessions and model switchingA lot of the engineering effort went into making the app feel invisible and fast: low-latency streaming, overlay rendering, desktop event handling, OCR/screenshot workflows, voice streaming, and interaction logic.Originally started as an experiment to see how far a desktop AI copilot could go. Ended up becoming one of the most technically challenging and interesting systems I’ve built so far.Still in beta.
