How does AI screen search work?

AI screen search captures your screen continuously, extracts text from every app via accessibility APIs (with OCR as fallback), transcribes audio, and indexes everything in a local database. You search by keyword, app, time range, or natural language AI queries.

Can I search everything I've seen on my computer?

Yes. With Screenpipe, every word that appears on your screen becomes searchable — across all apps, all windows, all monitors. It also captures and transcribes audio. Search by keyword or ask AI questions like 'What was the URL from this morning's standup?'

Does AI screen search slow down my computer?

Screenpipe uses about 1-3% CPU on modern hardware. It uses accessibility APIs by default (extremely lightweight) with OCR as a fallback. Most users don't notice it's running.

AI Screen Search — Find Anything You've Seen on Your Computer

TL;DR: AI screen search captures your entire screen continuously, extracts text via accessibility APIs (with OCR fallback), transcribes audio, and indexes everything locally. You can then search by keyword, app, time range, or natural language AI query. Screenpipe is the leading tool — open source, cross-platform, 100% local, with a developer API.

You saw something on your screen. A URL. A code snippet. A number from a spreadsheet someone shared. A message in a channel you can't find anymore. You know you saw it, but you can't find it.

Browser history only covers web pages. Slack search only covers Slack. Email search only covers email. File search only covers files you saved. There's no "search everything I saw today" button.

Until now. AI screen search captures your entire screen continuously, extracts text from every app via accessibility APIs (with OCR as a fallback), and lets you search across all of it — every app, every window, every tab.

How AI Screen Search Works

The technology is simpler than you'd think:

1. Continuous Screen Capture

The app takes screenshots at regular intervals (typically every 1-2 seconds). This happens in the background with minimal CPU impact — modern operating systems have efficient screen capture APIs.

2. Text Extraction (Accessibility + OCR)

Text is read directly from apps via accessibility APIs — the same system assistive technologies use. This captures text with 100% accuracy and minimal CPU usage. For content that accessibility can't reach (images, videos, GPU-rendered apps), OCR kicks in as a fallback. The result: every word you see on screen becomes searchable — including text inside images, PDFs rendered in a browser, code in your editor, messages in chat apps, and content in video calls.

3. Audio Transcription

In parallel, system audio and microphone input get transcribed. What people say in meetings, what you hear in YouTube videos, podcast audio — all converted to searchable text.

4. Indexed Local Database

The extracted text is stored in a local database with timestamps and app context (which app, which window). This creates a timeline of everything you've seen and heard, searchable by keyword, time range, or application.

5. AI Query Layer

On top of the search index sits an AI that can answer natural language questions. Instead of exact keyword matches, you can ask: "What was the API endpoint the backend team mentioned in standup?" and the AI finds the relevant moment.

What You Can Actually Search

Here are real examples of what AI screen search finds that other tools miss:

Cross-app search:

"What was the Figma link someone posted in Discord?" — searches screen content across both apps
"Show me the error message from my terminal this morning" — finds extracted text from terminal window

Meeting content:

"What numbers were on that spreadsheet during the finance review?" — finds screen content from the shared screen
"Who mentioned the deadline change?" — searches audio transcript

Lost context:

"What was I working on last Tuesday afternoon?" — shows a timeline of apps and content
"Find that Stack Overflow answer about React hooks" — even if you closed the tab

Code and development:

"What was the function signature I saw in the PR review?" — extracted text from code review tool
"Show me the database schema from the architecture discussion" — finds shared screen content

Common Questions

Does it slow down my computer?

Screenpipe uses about 1-3% CPU on modern hardware. Screen capture uses accessibility APIs by default (which are extremely lightweight) with OCR as a fallback, optimized to run efficiently in the background. Most users don't notice it's running.

How much storage does it use?

Roughly 1-2 GB per day of continuous use. The data is compressed extracted text and audio transcription, not video files. A 1TB drive holds months of screen history.

Can I exclude sensitive apps?

Yes. You can configure Screenpipe to skip specific applications or windows. Banking apps, password managers, or anything else you want excluded.

Does it work with multiple monitors?

Yes. Screenpipe captures all connected monitors simultaneously. Each frame is processed independently.
