Behind the scenes
We’ve built a bigger version of Prep for professors: a workspace to build and edit study materials for their students. We’ll soon be looking for professors interested in trying it out with their classes.
You didn’t get into teaching to fight with equation editors
Between grading, office hours, and the committee meeting you forgot about, who has time to hand-format a 40-question quiz? Retainium handles the tedious parts so you can focus on the teaching.
What you get
A single workspace where you build study packs: lessons, quizzes, and reference pages organized into courses and modules, including the math-heavy layouts that every other platform makes painful.
- Drag-and-drop page editor with a grid layout, so you can arrange text, formulas, and images exactly how you want them instead of fighting a single-column text box.
- Built-in formula library you can search by name or topic. Drop an identity onto the page and it renders perfectly every time. No copy-pasting from separate tools.
- Six quiz question types (multiple choice, fill-in-the-blank, short answer, matching, multi-step, and true/false) with full math notation support in both prompts and answer choices.
- Course and module structure so your material is organized the way students actually navigate it, not dumped into a flat list of files.
- AI authoring assistant that understands instructional design. Feed it your lecture notes and it drafts structured pages and quizzes you can review and edit. More on that below.
And we’re still building. New features ship every week based on what educators like you actually ask for.
Go from outline to finished pack in hours, not weeks
Retainium’s AI assistant was designed for instructional design, not generic chat. Hand it your lecture notes or a chapter outline and it will draft structured pages and quiz questions you can review and edit. It keeps notation consistent and formatting clean. You stay in control of every word; it just takes the grunt work off your plate.
An AI tutor that doesn’t give away the answers
Every pack comes with a built-in Socratic tutor for your students. When they’re stuck on a concept it asks guiding questions instead of spoon-feeding solutions, so they actually learn the material instead of copying it. And it’s designed to stay out of graded quizzes entirely, so your assessments stay honest.
Built for people who take course materials seriously
We work with:
- Professors building supplementary materials for their own courses
- Departments coordinating content across multiple sections
- Textbook publishers exploring digital study companions
If you care about accuracy, proper notation, and how students actually study (rather than just checking a box), we should talk.
Try it before you commit
We offer free trials for faculty and editorial teams. Build real content, test the AI workflow, and see exactly what your students will experience. No contracts, no credit card, no pressure.

Stop wrestling with equation formatting
Anyone who’s hand-typed a piecewise function in a quiz builder knows the pain. Retainium has a built-in formula library. Search for the identity you need, drop it on the page, and drag it where it belongs. The equations render beautifully every time, no raw markup required.
Calculus & Algebra Reference
Search the formula library, drop what you need onto the page, and arrange it with drag-and-drop. No hand-typing required.
