What Is Studio?

An AI workspace for turning your own material into summaries, notes, quizzes, and mindmaps.

Studio is still under active development and isn't listed in the main navigation yet. This page describes it for reference — expect things to change before it's fully rolled out.

Studio is a three-panel AI workspace. You feed it sources (PDFs, papers, videos, notes), chat with Epis about them, and generate study artifacts.

The Three Panels

Left — Sources

Add PDFs, images, exam papers, modules, YouTube links, or Bucket files. Toggle each on/off for context.

Middle — Chat & Actions

Ask Epis questions. Click action chips (Summary, Notes, Quiz, Mindmap) to generate artifacts.

Right — Vault

All generated artifacts live here. Open, share, or delete. Quizzes are interactive.
