How to Extract Text & Code from Screenshots with 100% Offline WASM OCR (Zero Cloud Uploads)
Extract JSON payloads, terminal outputs, and non-selectable UI text directly from browser screenshots without external API keys.
To extract text or code from any webpage screenshot using ClickSnap: 1) Capture the area or full page with ClickSnap, 2) In the Studio Editor header, click the "OCR Text" button, 3) ClickSnap executes local WebAssembly computer vision on the canvas pixels, 4) Review extracted text and code with preserved line breaks, and click "Copy 1-Click" to paste into your IDE.
The Frustration of Non-Selectable Text on the Modern Web
Every developer and designer encounters non-selectable text every single day:
- Error stack traces rendered inside canvas viewports.
- Figma mockups where copy-pasting is restricted by permission levels.
- Scanned PDF invoices and checkout receipts.
- Video tutorials and conference presentation slides.
Traditionally, extracting this text required uploading screenshots to third-party cloud OCR services or cloud AI APIs, introducing serious privacy risks and latency.
