Can startups using A.I. remake education?

Concrete uses for artificial intelligence (A.I.) continue to multiply as the technology improves. Earlier this week EdTech reported that Gradescope has raised 2.6 million from investors. The firm, started as a side project at U.C. Berkeley in 2012, makes software that helps STEM professors grade exam questions on handwritten tests. The company currently operates on a "freemium" model -- grading simple exam questions is free, while the A.I. feature (which is still a few months away) will be available for a price. "We want a feature that will offer the convenience of a Scantron without watering down the questions," said cofounder Arjun Singh.
