Automatic CAPTCHA filler for IISER Pune's Academic ERP
A Google Chrome extension that automatically fills in the "CAPTCHA" form element for IISER Pune's SAM portal (Academic ERP) login form.
Updated to use Tesseract.js 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)
- Download this repository as a zip file (either using the green 'Code' button or the releases tab on the right) and extract it anywhere.
- Go to chrome://extensions to manage your extensions.
- Enable Developer Mode by clicking the toggle switch next to Developer mode.
- Click the Load unpacked button and select the extension directory that you just unzipped. Remember to select the correct directory, it should have the core files directly under it (sometimes unzippers create a nested structure with another folder outside, with the same name).
On every instance of https://www.iiserpune.in/sam/roott/index.php that you open in Chrome, this extension will fill out the OCR result in the appropriate form field.
Uses OCR Space's free OCR API. PLEASE NOTE: The API (being free) may sometimes be down. Check this here. 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. The free API may sometimes be down, you can check this here.

- Error notif if the API call was bad or an answer wasn't returned
- Option for user to toggle on "Autosubmit form" (autosubmits form after the answer is filled in)
