SkillDiscs turns any source — article, YouTube video, PDF or GitHub repo — into a Disc: a guided course for you, plus clean structured context for your AI.

You don't just collect links, you build understanding:

a self-assembling knowledge graph, a voice tutor that explains and quizzes you, and concept maps across documents. Via API and MCP, any Disc becomes a skill for your agents. Try it free with the Quickstart — no account needed for your first Disc. Watch the 2-min demo or start at skilldiscs.com.

Features

Import & parsing

Any source in: article, YouTube video, PDF, GitHub repo, Office files, book, plain text, link
Clean PDF source view — figures described, equations rendered, tables kept intact
Toggle AI-explained ↔ original source
Multi-language (EN, DE, FR, ES)

AI tutor

Explain any paragraph on demand, with citations back to the exact source span
Self-quiz — multiple-choice, short-answer and free-recall checks
Explain diagrams & figures
Explain formulas & equations
Voice tutor — talk hands-free, interrupt with "wait, explain that again"
Read-along audio lessons
Level check — adapts to basics vs. deep detail
Speed reading mode (100–600 WPM)

Learning system

Guided course path from any source
AI-graded recall + smart review rhythm (weak concepts resurface at the right time)
Goals, study plan, badges & milestones, mastery snapshot, streaks

Knowledge & AI export

Self-assembling interactive knowledge graph (per Disc + across library)
Cross-Disk citations and compare-two-sources view
Auto-organized personal wiki
Export via REST API + MCP — Discs become skills for your agents
No account needed for the first Disc

Use Cases

Students — turn dense papers and textbooks into guided courses; ask "explain this paragraph/formula" until it sticks
Researchers — knowledge graph across papers, cross-Disk citations, compare two sources side by side
Devs onboarding into a new stack — convert repos, docs and tutorials into a guided path instead of bookmarks
AI/LLM builders — wire Discs into agents via MCP so your AI answers from sources you trust
"Read later" hoarders — every saved article becomes a learnable, queryable, quizzed Disc
Self-learners & knowledge workers — audio review, speed reading and spaced recall on the go

Hi! I built SkillDiscs because my "read later" list had quietly turned into a graveyard. I was saving great articles, papers and YouTube talks — and remembering almost none of them. Meanwhile my AI tools kept answering from random web sources instead of the material I actually trust. SkillDiscs takes any source (article, PDF, YouTube video, GitHub repo) and turns it into a Disc: a guided course with concept maps, a voice tutor you can interrupt ("wait, explain that part again"), and a knowledge graph that builds itself and connects concepts across everything you add. PDFs get special treatment — figures described, equations rendered, tables intact, and the tutor can explain any paragraph, diagram or formula and quiz you on it. Built for people who read a lot to learn — students, researchers, devs onboarding into a new stack — and for anyone wiring up agents that need reliable context. Via API and MCP, every Disc becomes a skill for your agents. Try it without an account: paste a link, and your first Disc is ready in under a minute.

Super cool idea. I especially like that each Disc becomes reusable context for AI agents, not just a course you consume once. Turning complex PDFs, videos, and repositories into interactive knowledge you can question, explore, and connect could make deep learning much more effective.
