This is a mechanism-based tautomer generator. Using Lewis formula as the only user input, which can be either an existing molecule or a molecule unknown yet, the software can simulate the practice of chemists writing acid/base catalyzed tautomerization and enumerate all the tautomers.
Although the demo videos in https://www.rosoft.website/ were prepared mainly for "Reaction-Stereochemistry", it also can be used as the reference of the software.
