Every tool here is free, openly licensed, and works offline. No accounts. No tracking. No engagement optimization. Just real instruments for real learning.
“Does this restore the capacity to think, or does it replace it?”
If it puts a learner in genuine encounter with something real — a star, a word, a circuit, a question that does not resolve, a piece of music they made themselves — it belongs. If it optimizes for engagement, it does not.
Install everything below with a single command. No accounts required. All tools run offline after initial download.
The setup script installs tools in six layers. Each layer is optional and can be
installed independently. Run with --help to see options.
Foundation tools for ages 2–10. Art, math, typing, exploration.
180+ educational activities for ages 2–10. Math, reading, science, geography, music, logic games. The most complete open educational game suite that exists.
Ages: 2–10 · GPL · gcompris.net
Professional digital art studio. Brushes, layers, animation, vector tools. Making is different from consuming — this is a tool that asks children to create rather than receive.
Ages: 6+ · GPL · krita.org
Mental math and typing practice through gameplay. No scores uploaded anywhere. No leaderboards that compare children against each other. Just practice, at their own pace.
Ages: 4–12 · GPL
Instruments for wonder. A child who can name the stars is a navigator, not a consumer.
600,000+ stars. Realistic 3D sky from any location on any date. Constellations, planets, nebulae, eclipses. The real night sky, rendered honestly.
Ages: 6+ · GPL · stellarium.org
Interactive making from MIT Media Lab. Stories, games, animations, simulations. Visual programming that teaches logic through creation.
Ages: 6+ · BSD · scratch.mit.edu
Write melodies. Hear them played back. Make beats. Compose. Music is one of the oldest technologies for processing experience. A child who can write music has a tool no algorithm can replicate.
Ages: 8+ · GPL · musescore.org / lmms.io
Spaced repetition — cognitive science applied to memory. The content is what the learner puts in. Star names, etymology, vocabulary. The system does the remembering. The learner does the choosing.
Ages: 8+ · GPL · ankiweb.net
The offline K–12 platform that runs everywhere.
Offline K–12 education platform from Learning Equality. Khan Academy, OpenStax, CK-12, EngageNY. 173+ languages. Tested in schools, refugee settlements, and rural communities worldwide.
Ages: K–12 · MIT · learningequality.org
Interactive science from CU Boulder. Build circuits. Simulate gravity. Explore molecules. Physics, chemistry, biology, math — all interactive, all offline.
Ages: 8+ · phet.colorado.edu
14 curated Gutenberg texts downloaded automatically: Frankenstein, Alice in Wonderland, Republic by Plato, Meditations, Calculus Made Easy. Readable with Piper TTS voice reader.
All ages · Public Domain · gutenberg.org
Local AI with a Socratic prompt: asks questions, never answers. “What makes you think so?” Not a teacher. Not a search engine. A presence that wonders alongside the learner.
Ages: 8+ · Requires Ollama · IBOR v1.5 compliant
Linguistic archaeology. Reclaim the roots of words. A learner who knows that “government” comes from the Latin gubernare — to steer — reads every headline differently.
Ages: 8+ · Built into Education Engine · Offline-first
Access to knowledge is not guaranteed. It has never been guaranteed. Education Engine supports a Sovereign Archive Node — a local copy of Wikipedia, Wiktionary, Project Gutenberg, and more, stored on your own hardware and verified against cryptographic hashes.
When a learner uses the archive, they are reading from a source that cannot be de-platformed, censored, or paywalled. The archive endures because you hold it.
Every tool on this page is openly licensed: GPL, MIT, BSD, Creative Commons, or Public Domain. No proprietary software. No license keys. No subscription walls. The setup script installs only from official package repositories and project sources. You can audit every line.
For the best experience, use LimenGate, the sovereign browser with built-in tracker blocking and fingerprint spoofing.
