A few useful answers

Questions about C4Y.

Who is C4Y for?

C4Y is being built for independent tutors, learning centers, and education teams. It brings lesson materials, live teaching tools, learner submissions, and instructor feedback into one workspace.

Can I use my existing teaching materials?

Yes. Bring PDFs, images, video, audio, and course files into an ordered lesson. Reuse preparation material while keeping each class’s annotations separate.

How does AI fit into the platform?

We’re developing AI assistance around a review-first workflow: request material, inspect the preview, refine it, and choose what to use. AI-assisted preparation is in development; an educator remains in control of what reaches learners.

Can learners submit work and receive feedback?

Yes. Assignments support text and file submissions, instructor scoring, rubric feedback, and a history of work and grades. Focused practice activities provide worked explanations after submission.

What happens after class?

Save the whiteboard, prepare a PDF, and assemble a personalized recap with selected materials and homework. Assign homework to the relevant learners within their course.

How can I see C4Y in action?

Book a conversation with our team. Tell us how you teach and which workflows matter most, and we’ll focus the demo on your needs. We’ll also discuss availability, setup, and pricing directly.
