Jigao is a collaborative, AI enhanced examination platform designed for modern educators and learners who demand both flexibility and integrity. Unlike traditional rigid quiz tools, Jigao bridges the gap between honest, peer-to-peer learning and secure, proctored assessments.

Built for adaptability, Jigao allows educators to create dynamic question sets, collaborate with co-teachers, manage access permissions, and conduct exams in three distinct modes : Friendly, Protected, and Public each tailored for different trust levels and monitoring requirements.

group of honest learners (ideally 2-5 people) who all have access to a particular question set. Now they want to conduct an exam among themselves. As they all have question set access they can view the questions if they want (that’s not fair though) but it creates a same page understanding between them.

• Only Users having set access can attend
• No monitoring system, so everyone is participant

• Two types of user role :
  • Controller : Monitors Exam (Users who have set access)
  • Participant : Attend Exam ( Users invited or join request accepted by any controller to attend exam)
• Participants are invited by monitors via mentioning user(email)
• Participants can send Exam Join Request from exam page and Request can be accepted by any controller.
