SnapTextify is a secure, 100% offline OCR Chrome extension powered by local WebAssembly binaries to instantly copy text and extract code from YouTube videos, images, and copy-restricted websites. Operating with zero server uploads, it delivers highly accurate, private, and zero-latency (~300ms) image-to-text conversion directly in your browser sandboxed environment.

Note: You can audit and verify this offline capability at any time by monitoring the browser Developer Tools Network tab (F12) during a scan overlay copy operation. For complete transparency, we have open-sourced our core offline OCR WebAssembly model: inspect the GitHub Proof-of-Concept Repo.

Frequently Asked Questions

Got questions? We have answers. Find everything you need to know about SnapTextify below.

What is SnapTextify and how does it extract text from my screen?
SnapTextify is a secure, 100% offline Chrome extension that lets you drag a selection overlay box over any video frame, document, or webpage to instantly extract and copy text using in-browser WebAssembly OCR.
Is my data safe with SnapTextify, or does it upload screenshots to the cloud?
No data is ever uploaded to any server. All image extraction, cropping, and OCR operations are executed entirely on your local machine within a sandboxed environment using local WebAssembly binaries. Your privacy is 100% guaranteed.
How does the offline OCR auto-detection support multiple languages?
SnapTextify utilizes a compiled local Tesseract OCR engine that auto-detects and transcribes 9 different scripts simultaneously: English, Bengali, Hindi, Spanish, French, German, Portuguese, Russian, and Arabic, without requiring manual language toggles.
How do I copy code from a YouTube video safely using this extension?
To copy code or prompt text from a YouTube video, pause the video on the frame showing the code, press Alt + C (or click the extension icon) to freeze the screen, and drag a selection box over the code block. SnapTextify's local WebAssembly OCR engine reads the text in ~300ms and copies it directly to your system clipboard.
Can I use SnapTextify to copy text from copy-protected or locked websites?
Yes. Since SnapTextify captures a secure screen overlay at the viewport level, it completely bypasses any CSS or JavaScript blockades (such as right-click disabling, copy-protection scripts, select-disabled CSS, or iframe locks). If the text is visible on your screen, SnapTextify can copy it.
Does the local WebAssembly OCR engine require an internet connection?
No. Once SnapTextify is installed, the compiled WebAssembly binaries and OCR models run entirely within your local browser sandbox. You can capture, extract, and copy text from any image or video offline, even when your computer has no active internet connection.
What is included in the free tier of SnapTextify, and how do I scan more?
The free tier grants you 3 local OCR scans per day to extract text. To unlock higher scan limits or get unlimited lifetime usage, you can upgrade to one of our premium packs starting at just ₹149.
How does the local UPI QR payment verification work to unlock my license key?
When paying via local UPI, you simply scan the dynamically generated QR code, pay the exact amount using any UPI app (like GPay, PhonePe, or Paytm), and enter your 12-digit UPI Transaction ID / UTR number in the checkout screen. Our backend verifies the UTR reference instantly, and your license key is auto-generated and emailed to you, typically within 10 to 15 minutes.
On how many devices or browsers can I activate my premium license key?
A standard premium key can be activated on up to 3 separate Chrome browser installations simultaneously. If you purchase our Unlimited pack, your license key supports activation on up to 5 concurrent browser profiles or devices.
