Does Soulver use machine learning/AI?

Soulver is powered by SoulverCore, which scans expressions for pre-defined syntaxes and evaluates any valid mathematical expressions it finds. It does not use machine learning algorithms.

If you're curious about how to build something like SoulverCore, read Crafting Interpreters. You could also watch this great talk by Nick Lockwood, and check out his example of a math parser.
