About Psetter

Psetter is a visual math editor for MITx that lets you build mathematical expressions directly in compatible answer fields instead of typing MITx syntax by hand. Create fractions, roots, exponents, functions, symbols, and complex expressions visually. Psetter converts what you build into the input format MITx expects, making it faster and easier to enter math while keeping your focus on the problem instead of the syntax. Psetter runs locally in your browser. Math parsing and conversion happen on your device, and answer content is not sent to a Psetter server. Psetter is an independent project by Pedro Villafranco and is not affiliated with, endorsed by, or sponsored by MIT or MITx. Support: psetter@villafran.co Privacy: https://psetter.villafran.co/privacy
