Rescuing the golden age
of desktop software.
Between 2000 and 2015, independent developers and computer science researchers created some of the most algorithmically brilliant software in history: Bernhard Hobiger's HoDoKu, Carl Burch's Logisim, and dozens of meticulous logic engines.
As the web moved forward and mobile devices took over, those tools became trapped inside legacy Java .jar files. Modern macOS blocks unsigned executables, iPads and Chromebooks cannot run Java desktop apps, and HiDPI screens break old Swing interfaces.
Revisited Labs was born to solve that problem. We rescue these masterpieces, modernize them with clean TypeScript and modern Web Standards, and enhance them with Symbolic AI Coaches that help students, puzzle lovers, and engineers understand why a move works.
