# How Odrivyn works

> A small Rust app on your Windows computer listens to the call, finds answers in your files and your company brain, and shows them in a window only you can see.

## Steps

1. **Install a 6 MB app**: Odrivyn installs in seconds without admin rights. It stays out of the taskbar.
2. **Approve it in your browser**: The app shows a short code; you approve it while signed in on the web. No password is typed into the app.
3. **Add what you know**: Upload documents or a web page, or join your company to share what it knows. Odrivyn reads them so answers can quote them.
4. **Listen and get answers**: Odrivyn transcribes both sides of the call. When the other person asks something, it searches your material and writes what to say.
5. **Get the recap**: Stop listening and the recap and follow-up are written from the transcript, which stays on your computer.

## Why screen share can't see it

Odrivyn asks Windows to exclude its window from capture (the same display-affinity setting that keeps protected video out of screenshots). Zoom, Meet, Teams and recorders see the desktop behind it. Nothing joins the meeting, so there is no bot in the participant list.

## How the company brain answers

When a question comes in, Odrivyn looks through your own files and the ones your company shared, finds what answers it, and quotes it with the file and page.

## What stays on your computer

Transcripts, answers and recaps are stored in a local database on your machine. Audio goes to the speech provider and text to the AI provider to be processed, and neither we nor they keep it.

## Built in Rust

- Written in Rust with Tauri; uses the WebView2 that ships with Windows instead of bundling Chromium.
- Installer: 5.7 MB. Installed: 20 MB.
- Private memory: about 34 MB for the Rust core, 153 MB including its WebView2 window processes (Odrivyn 1.9.8, Windows 11, open and signed in).
