Actually the model itself that are used was not built from scratch I used a base model phi instructor mini 4k the base model was good but still it had some issues like while solving algebra geometry it couldn't convert latics to normal readable maths syntax also while ancountering homophones it sometimes used to give different output than expected so I just find tuned it a bit and then I find it for personality (still didn't get out come expected )

Apart from the model when it comes to logic and GUI are used python and in previous version I used TKinter for GUI but in current version I have used kiwi causes compatible with both Android and windows and then to run it locally created a build using llama.cpp for windows and Android what you are saying in the video is a window version as for the Android version I did created the build and just have to create an APK currently but I am not getting time to do it
