Describe what you want to learn. OpenKnowledge researches real sources, builds a curriculum around your time, and writes every lesson with the citation to prove it.
No credit card. The free plan includes a monthly AI allowance.
No slide decks, no generic outlines. Every course is researched and written fresh for what you asked for.
Type a topic or a goal — “quantum computing”, “get conversational in Korean”, “understand game theory for my job.” A short chat fills in the gaps: your level and your reason for learning it.
OpenKnowledge searches Wikipedia and the open web for sources, reads them, and drafts a curriculum shaped around what you told us — modules, lessons, and worksheets in a sensible order.
Each lesson is written prose with worked examples, diagrams, and practice problems — every factual claim linked back to the sentence it came from, so you can check it yourself.
The parts that make it a study tool, not a chatbot with a topic.
Claims carry a citation back to the original source sentence. If the model can't verify something against a real source, it doesn't get to say it plainly.
A quick skill gets a couple of sessions; a subject taken seriously gets as many as it needs — never an arbitrary twelve-chapter outline padded to look thorough.
Multiple choice, fill-in-the-blank, and written response — checked against a rubric, with explanations shown only after you've answered.
Flowcharts, graphs, and worked equations are generated alongside the prose when a topic calls for them, not bolted on afterward.
If Wikipedia has written about it, OpenKnowledge can turn it into a course.
Every plan gets the exact same OpenKnowledge — grounded citations, paced curricula, self-marking worksheets. The only difference is how much you can learn each month.
