In their own words

ClassDojo

ClassDojo connects teachers, families, and children around learning at school and at home. Teachers can share photos, videos, messages, and class updates, and use feedback points to recognize student skills and behaviors. Private teacher-family messaging supports direct communication. The free ClassDojo plan costs nothing and includes teacher messaging, class points, and class story updates. Plus adds Homework Helper, access to more than 2,000 Magic Books stories, and the option to automatically add school events to a Google or Apple calendar. The subscription can be shared with up to three other grown-ups. ClassDojo is available on the web, iOS, and Android, and teachers can use it alongside Google Classroom. The latest app requires iOS 17 or later or Android 8 or later; Kindle devices are no longer supported. ClassDojo says it complies with COPPA, FERPA, and GDPR in Europe, and that it does not share user or student information with advertisers or marketers.

Piazza

Piazza is a course Q&A platform connecting students, teaching assistants, and professors around coursework. Its wiki-style format lets participants edit shared responses, with one student answer and one instructor answer for each question. Students can post anonymously to classmates, or anonymously to the instructor if the instructor permits it; instructors can endorse questions and answers. Course pages can hold announcements, course information, syllabi, assignments, lecture notes, and links. Participation reports show instructors who asks, answers, edits, or reads, as well as when questions arise during the term. Piazza lists integrations with Blackboard, Moodle, Sakai, Desire2Learn, Canvas, Jenzabar, and Angel. Integrated rosters can enroll users with appropriate roles, and users can sign in through the LMS. Piazza is available on web, iOS, and Android, with class alerts in its mobile apps. It says student email addresses and course enrollment details are accessible only to class instructors, and describes technical, administrative, and physical safeguards. Founded in 2009, it is headquartered in Palo Alto, California. A contribution-supported plan is free; paid instructor licenses start at $379 a month, billed per term.
