 A Google Chrome extension that automatically fills in the "CAPTCHA" form element for IISER Pune's [SAM portal](https://www.iiserpune.in/sam/roott/index.php) (Academic ERP) login form.
 
-Uses OCR Space's [free OCR API](https://ocr.space/ocrapi).

+### *V2.0* - Aug 08, 2024
+Updated to use [Tesseract.js](https://tesseract.projectnaptha.com/) to perform the OCR, instead of using an API. 
+ * A lot faster than using the API (based on my usage)
+ * API was down often (kind of a given, was for free)
+ * Honestly this was mostly done because I realised that I shouldn't freely let out my own API keys in my code :)) (yes I realise it's there in the history of this repo, too lazy to remove all of that now)
 
 
-### *V1.0*
-Selects image tag, converts it into base64, passes it to a POST call for the OCR API, parses returned information, fills in the form element.

 The OCR results are not always perfect.
 edit line28 of auto-login.js to replace the API Key with your own API Key, if you'd like.
