Tutor Stores is an online marketplace for finding and booking private tutors for a range of subjects. It supports booking of both in-person lessons in a chosen location and also remote tutoring. Tutor Stores does not offer its own video conferencing tech – rather it encourages tutors to offer lessons via third party tools like Skype (which it anticipates integrating via an API in future). Tutor Stores focuses on structuring its marketplace-including by adding a ranking algorithm that uses machine learning for recommendations and classification of tutors, based on their profile.
