How Overlay AI works?
Get real-time guidance without anyone knowing. Here is how our localized pipeline operates during your calls.
Overlay listens in to the conversation
It picks up the context of your meeting in real-time. Subtitles are captured from Google Meet and relayed secure and offline.
Assists you instantly with tailored AI
Type your role, level, and preferred model — Overlay adapts its answers specifically for you.
Answers fly in, no one else sees them
Overlay renders outside your screenshare compositor. Zoom, Meet, and Discord capture show a clean blank — only you see the AI.
1. Relayer Capture
Listens locally to your meeting transcript stream without sending sound or captions to the cloud.
2. Prompt Compiler
Applies your role, level settings, and guidelines, selecting the perfect model to generate precise answers.
3. Protected Output
Renders answers invisibly to attendees, utilizing compositor hooks to block overlays from screenshares.
Where Can Overlay AI Help?
Works across every high-stakes professional scenario — in real-time, without anyone knowing.
Meeting & Conversation Summary (/convo-summary)
Scrapes all caption chat bubbles from your live Google Meet conversation and streams a structured summary of key technical points, decisions, and immediate next steps, keeping you and your team aligned.
Document Summarizer (/summarize)
Summarize any attached document (PDF, text, or code up to 10MB) instantly. If no file is currently attached, running this command opens your native OS file picker to select one, letting you reference specs, API schemas, or briefs on-the-fly.
Presentations & Client Calls
Access complex API names, integration rules, and deployment specs in under a second. In-Short Mode gives you brief rapid-fire summaries when client questions check your recall.
High-Privacy Environments
Compositor protection filters your window out of OS screen capture. Attendees, screen recorders, and conferencing platforms see only a blank background layer.
Technical & Coding Interviews
Never freeze on sliding window, system architecture, or graph traversals. Overlay streams optimal complexity answers, code snippets, and conversational prompts dynamically as you speak.
Technical Reviews & Architecture
Keep DB schemas, sharding techniques, caching strategies, and queue tradeoffs right at eye level. General Mode populates structured templates instantly.
Custom Role, Level & Model Selection
Configure any specialty context you desire. By matching custom roles and seniority levels with the LLM of your choice (Gemini, Claude, GPT), Overlay's applicability reaches far beyond default profiles.
