Assalamoalaikum,
Yes, one can do anything like what you want with python-based scripts that communicate with Selenium to automate the web browser. Another option is to create our own custom browser and use it to run Quillbot in an automatic mode (fetching data from Mysql and using it for request and responses).
As with any project requiring the construction of bots that interface with third-party technologies, there is a high likelihood of unforeseen issues that will need to be resolved. I've given myself a 30-day deadline to compensate for this. This will most likely be completed sooner, but it is preferable to have a clear picture.
I look forward to hearing from you and continuing our discussion on the project.
Regards.
P.S. Quillbot was extremely helpful in improving my bid. :-)
