In 2020, Revisor, a neural network-based election-monitoring software Revisor, analysed footage recorded at 1,238 polling stations in 29 Russian regions on polling day in 2018 in an attempt to retroactively uncover the electoral fraud widely believed to have taken place. Indeed, after counting votes and comparing them with the official turnout, the software found discrepancies in 11 regions so huge that it made it impossible for the election result to have been accurate, according to another Revisor creator, Vlad Matveyev.

"How can Putin be considered to have won if we don't know how entire regions voted?" says Ivan Shukshin, one of Revisor's creators.
