Class communication outside the classroom.

ClassTalk empowers teachers to communicate instantly with their classes through SMS and email, keeping school subjects and class deadlines at the top of a student’s mind.

ClassTalk was made by Code for America in partnership with the City of Boston.

Teachers can send 160-character messages to an entire class instantly or schedule one to be sent at a future time. Students can reply to their teacher’s messages via phone or email, providing instant, low-barrier access to their teacher even after class is dismissed. ClassTalk brings out-of-school communication to the devices teachers and students already use everyday.

There was a working website for the project at, but it is no longer accepting new accounts. If you are interested in maintaining the project, you can get in touch with Scott Silverman, the project’s lead.
