SubSchool

What SubSchool is

SubSchool is an AI teaching platform where teachers create and sell courses, run tutoring and grade homework in one place. Its home page headline is "Create courses, run tutoring, and grade homework with AI," and it describes the product as "an all-in-one platform for online teaching where you can create and sell courses and run tutoring without building a website or wiring payment systems." The company behind it is SubSchool LTD, with an address in Ruislip, United Kingdom.

The solutions menu shows who it is for: teachers, tutors, course creators, students, parents, schools, online schools, tutoring centers and businesses. It works from both sides. Educators sign up to build courses and offer tutoring, while learners sign up separately to browse courses, find a tutor and browse schools. A buyer's guide on SubSchool's blog describes the product as built "for both creation and distribution," with a marketplace option alongside the teaching tools. The site is offered in English, Spanish, Italian, German, French, Korean, Russian, Ukrainian, Chinese, Hindi, Swahili and Georgian.

What an educator actually gets

Course creation from uploaded lectures. A teacher can create a first course simply by uploading lectures: SubSchool's AI then writes lesson descriptions, divides the material into modules and adds homework assignments. The blog adds that a teacher can upload a batch of videos and let the AI structure the course, or build lessons manually and have the AI generate homework from each lesson's context. When lessons are added, the AI can also create covers, subtitles and homework assignments, which the home page calls handing the routine to AI.

Math and chemistry editors. For subjects that need notation, built-in mathematical and chemical editors let a teacher add formulas and chemical compound diagrams when writing lesson articles and describing homework.

AI grading with teacher review. The AI turns lesson materials into homework, checks and course visuals, and grades essays and video answers, which the home page says saves hours of routine work. It checks solutions submitted as an essay, a presentation or an interview, and the teacher can still open the student's solution, see the AI's assessment and correct it if necessary. The blog says interview-format tasks inside courses make SubSchool usable for corporate training and for what it calls EduHire flows, where learning and assessment feed hiring.

Adaptive homework. Personalized homework is meant to give each student the right level of challenge: adaptive assignments adjust to a student's performance so learners neither get bored nor get stuck.

Selling by course, module or lesson. A course can be sold whole, by module, or one lesson at a time. SubSchool presents single-lesson sales as a way to let students try one lesson before committing, which it says lowers the entry barrier, builds trust faster and increases conversions. For students, the pitch is that they can judge a course's quality for themselves and buy only the lessons they need right now.

Entry-to-exit exam rating. SubSchool rates courses by the gap between an entry exam and an exit exam: "Bigger improvement = higher course rating and stronger trust." A course that measurably moves students forward earns a better rating than one that does not.

Tutoring and live lessons. Built-in one-to-one tutoring lets a tutor set availability, approve bookings and run lessons from one place, and a session link is created automatically. Live lessons can be one-on-one or for groups of students within courses. Teachers can also create a tutor profile so that students from their courses come to them for additional lessons.

Recordings and homework in one thread. Every tutoring call is saved, and homework sits right next to the recording, so assigning, submitting, reviewing and tracking progress happen without switching tools. The product menu also lists schools and analytics, and educators can view statistics on their teaching. SubSchool's own product overview describes the whole workflow as connecting content, tutoring, assessment and teacher review.

What a learner gets

Students buy courses starting from a single lesson, complete assignments and choose tutors. They find a tutor and book a specific time; the cost is calculated automatically and deducted from the student's balance according to the recorded length of the lesson, so they pay for the time actually spent. Students join lessons from the chat, where they also receive lesson recordings and homework for the lessons they have taken. Lessons can be read as text or watched as videos and presentations, at the student's own pace and in their preferred format. Separate student sign-up and student login keep the learner side apart from the teacher tools.

Pricing and resources

The home page prints no prices; a pricing page sits in the product menu. Teacher and student sign-ups are separate. Resources include a help center, articles and guides, free tools such as an AI course outline generator that turns an idea into a reviewable teaching structure, templates and comparisons, and the product menu also lists a Codex MCP integration. The blog's buyer's guide, written by Maksim Mamchur, urges creators to count the real monthly cost of a platform, including the email tool, video hosting, integrations, payment fees and their own time, which is the case SubSchool makes for doing course creation, tutoring and grading in one place. The same guide sorts teaching businesses by the job the platform has to do and places SubSchool where teacher-led learning matters: lesson-level structure, homework and feedback cycles, and single lessons sold as a low-friction trial, plus interview-format tasks with scoring for hiring-style assessment. It sums up the fit as less setup, faster publishing and better learning operations, with a marketplace option on top.

Who it suits

SubSchool suits tutors and teachers who run lesson-by-lesson courses with homework and feedback, and who want live tutoring, recordings and assignments in one thread rather than spread across tools. The single-lesson sales option fits a teacher whose students want to try before buying a full course, and the entry-to-exit rating rewards courses that show real improvement. Math and science teachers get formula and chemistry editors, and course creators with a backlog of recorded lectures can let the AI turn them into a structured course with homework.

The interview-format grading also opens it to companies running training or hiring assessments. A school or tutoring center can use the schools and analytics side, though the pages say less about administration than about teaching.
