After freeing the wallets of more than two million students, Boston-based Boundless is now looking to ease educators’ stress. The textbook replacement startup announced Thursday its new Boundless Teaching Platform, a tool professors can use to customize content, all while integrating the company’s affordable alternative into their classroom.

“Boundless started with students first, giving them an affordable, dynamic alternative to expensive textbooks,” Boundless Founder and CEO Ariel Diaz said in a statement. “Our next step is to give educators the freedom to teach in a way that captures students’ imagination and interest.”

The Boundless Teaching Platform is free for educators to use, and offers up high-quality textbooks in more than 20 subjects. By simply dragging and dropping chapters or sections, teachers can create a Boundless book unique to their class, as well as utilize PowerPoint- or PDF-powered pre-built, customizable lecture slides they’re later able to share with their colleagues.

What’s more, the new platform provides a dashboard educators can use to assign readings or quizzes and then monitor students’ activity.

On the student side of the technology, costs ring in at $19.99 per assigned textbook. With that price comes Boundless’ recently-debuted adaptive learning technology, however, that’s designed to engage students with quizzes, a “smarter” flashcard system, summarization, annotation and more.

Boundless also offers mobile apps and more than 20 introductory level textbooks for free on its website with no registration required — further lessening the financial burden on students.

“For many subjects at the introductory level, the content that students learn hasn’t fundamentally changed in decades,” said Professor Gavin Buffington, chair of the Department of Physics at Fort Hays State University, in a statement. “Yet textbook companies continue to charge premium prices.”

Buffington went on to sing Boundless’ praises, adding:

I’m using a Boundless textbook this semester in my Engineering Physics I class, and I’ve been impressed by the quality of content, as well as the company’s responsiveness to user comments and requests. We’re planning to use the book again in the spring and fall of 2014 — these new tools for educators will only enhance my ability to customize content, give assignments and interact with students on their progress in class.

To celebrate Boundless’ next step into the digital age, the company will be hosting an unveiling of the platform at their downtown office on Thursday, as well as a discussion on the future of educational content. Open to all ed-tech enthusiasts, the event will be held from 6 to 8 p.m. Anyone interested can register for free here.
