Education, Learning
and Everything Between
Free courses, science and math references, history archives, and every tool for learning something new, whatever the subject.
Streaming platforms below are legitimate and free. Downloading sections may sit in a gray area depending on the source and your location, so use good judgment.
Whether you want a full university curriculum or a single afternoon skill, these streaming platforms and course indexes cover it, from MIT's entire lecture catalog to community curated course search engines.
edX
Free university level courses from Harvard, MIT, and dozens of other institutions, with optional paid certificates.
MIT OpenCourseWare
Nearly all of MIT's undergraduate and graduate course materials published freely online, lecture notes included.
You can grab premium, paid courses for free through these sources, but come prepared: run an adblocker and a link shortener bypass extension before clicking through, since most of these rely on ad-heavy redirect chains to stay funded.
- Course Busters, another course access aggregator
- AfraTafreeh, free video courses and books across several technical subjects
- CertCommunity, IT certification course access
- Infinite Courses, another large paid-course mirror index
- HacksNation Courses, a forum thread aggregating course drops and requests
- Online Courses Club, a browsable catalog of freely mirrored paid courses
- PimpMyMoney, course drops focused on business, finance, and marketing content
Beyond formal courses, this space is full of interactive simulations, encyclopedias, and virtual museum tours that make abstract subjects tangible, from walking through the Vatican Museums to running physics simulations in your browser.
From interactive physics simulators to full calculus textbooks, this is the backbone reference layer for anyone studying STEM, split across physics, math, engineering, chemistry, and biology.
The Feynman Lectures
The complete, freely hosted lecture series that remains one of the best physics introductions ever written.
WolframAlpha
A computational search engine that solves equations, plots graphs, and answers factual queries directly.
Physics, engineering, and chemistry all lean hard on interactive simulators. Falstad, PhET, and ChemTube3D are worth bookmarking early since they cover the widest range of topics.
Everything from raw NASA data feeds to full flight simulators lives here, useful whether you're tracking a rocket launch or just want to see the scale of the observable universe.
History, philosophy, economics, and world data sit together here, letting you trace anything from ancient mythology to modern global trade statistics.
Practical, hands on learning for skills that fall outside a traditional classroom, from music theory to figure drawing to Morse code.
Drawabox
A structured, exercise based drawing course built around fundamentals rather than shortcuts.
Proko
In depth figure drawing and anatomy lessons taught by a working professional illustrator.
With this much breadth, pick one thread and follow it before branching out.
- Want structure? Start with edX or MIT OpenCourseWare for a real syllabus
- Want something visual? PhET and 3Blue1Brown make abstract ideas click fast
- Want a hobby, not a degree? Drawabox or JustinGuitar are the best paced starting points
Every route into a new language lives here, from structured courses to native media immersion, exchange partners, and dictionaries for both major and lesser known languages.
Multi-Language — the general toolkit that works no matter which language you're learning, covering comprehensible input, media-based immersion, and reference tools.
Language Exchange — communities and apps that pair you with native speakers for live conversation practice, the fastest way to stress-test what you've learned.
English — from ESL fundamentals through IELTS prep, covering pronunciation, listening, and writing practice for learners at any level.
Japanese — resources built around real immersion, learning grammar and vocab directly from anime, manga, and visual novels rather than flashcard drilling alone.
Korean — structured lessons and Hangul fundamentals, from a well known community-run Discord to dedicated grammar and typing practice sites.
Chinese and Cantonese — Mandarin and Cantonese resources together, covering stroke order, tone practice, and dictionaries for both spoken varieties.
European Languages — Spanish, French, and a handful of smaller European languages, from comprehensible input libraries to grammar-checking tools.
German — a compact but reliable set covering a free official course, a large learning community, and translation dictionaries.
South Asian Languages — Urdu, Sanskrit, and Tagalog resources, including grammar overviews and community-maintained resource compilations.
Sign Languages — dictionaries and learning platforms for ASL, BSL, and international sign, plus one multi-language index for less common sign languages.
Constructed Languages — Esperanto, Toki Pona, and a few niche conlangs with dedicated learning communities, for anyone curious about invented rather than natural languages.
Pick a route that matches how you actually like to learn.
- Want structure? Language Transfer or your target language's dedicated course (DW German, TalkToMeInKorean) gives you a syllabus
- Want immersion? Language Reactor or Japanese's Immersion Kit teach through native media instead of textbooks
- Want a conversation partner? Tandem or Conversation Exchange connect you with native speakers directly
