PhotoMatch is an application that can shoot, identify and solve algebraic problems through a camera. It was recently reported by domestic scientific and technological media, so I think you may be talking about this software. But it doesn't meet your claim that you can solve advanced mathematics, because at present, PhotoMath's ability includes functional problems such as fractions, decimals, linear equations and logarithms. However, the development team said that they will increase their ability to solve advanced mathematics problems in the future.
