A humanities education that remembers you
Epoché turns 2,400 years of philosophy, science, and political thought into guided Socratic lessons — hand-authored, argued with you, and scheduled back just before you'd forget.
165 thinkers · 825 hand-authored lessons · no ads, nothing to buy mid-lesson
The method
Try it
This is one beat of a real lesson. Sophia never grades you and never lectures — whatever you answer, she answers back.
No verdict. No answer key. A harder question, put back to you — that is the method, and it is how an idea becomes yours.
Every lesson works like this →ἐποχή
epoché (n.) — the suspension of judgment. The pause the sceptics prized: the moment before you decide, where thinking actually happens.
This whole place is built to hold you in that moment a little longer.
The memory engine
Every idea you learn circles the fire. Left alone, its orbit decays — so Epoché has you recall each one just before it falls, and every recall roughly doubles how long it can safely be left alone. That doubling is spaced repetition. Click any idea to boost it.
Five ideas in orbit. The lower they sink, the sooner they burn.
Higher orbit · longer period · fewer visits — Kepler would approve.
The library
Every thinker in Epoché answers another. Touch a star to meet them.
Twelve of the one hundred and sixty-five. In the app this is a living globe — every pin a five-lesson course, lit as you learn.
Counted by script, not by claim — nothing in the library is generated on the fly.
Guided journeys
Ordered journeys across the globe — each thinker inherits the last one's open question, until the thread completes in a named constellation.
Thales' water to Aristotle's unmoved mover — the conversation that taught the West to argue.
Zeno's painted porch to the emperor's private journal — a philosophy built to be practised.
Baghdad's House of Wisdom to Newton's laws — how looking carefully became knowing.
The Buddha's diagnosis of suffering, and the schools that spent two millennia answering it.
Testimonials were hard to come by — the faculty has been dead for centuries. Their views on learning survive.
“While we teach, we learn.”
“It is impossible to learn what one thinks one already knows.”
“Learning without thought is labour lost; thought without learning is perilous.”
Honest by design
XP and mastery medals are earned by finishing new material or proving recall. Nothing rewards mere scrolling, and nothing can be bought.
No gems, no lives, no countdown timers. A gentle streak that forgives a missed evening. The reward for learning is knowing.
Sophia keeps a memory of how you think, and every dialogue starts where the last one ended. You can read — and erase — every line of it.
“Last week you argued that virtue needs luck. Tonight, test that against the Stoics.”Before you ask
The core library is free, forever — with a monthly allowance of new lessons. Reviewing what you've already learned is never limited. Epoché Plus lifts the allowance; there is nothing else to buy, and nothing inside a lesson ever asks for money.
No. Every step of every lesson is written in two registers — Introductory and Expert — and you can switch mid-lesson. Sophia's opening conversation finds your level in about two minutes, without feeling like a placement test.
No. All 825 lessons — 12,375 teaching steps — are hand-authored to one teaching schema. The AI serves the pedagogy, not the other way round: Sophia questions you about authored material, checks your recall against authored marking keys, and never invents the curriculum.
Your tutor across every surface: the placement conversation, Socratic dialogue, the teach-it-back exam, recall marking. She keeps a memory of how you think so each dialogue starts where the last ended — and you can read, export, or erase every line of that memory at any time.
Every idea you learn is scheduled for review with FSRS — the modern spaced-repetition algorithm — tuned to your own memory over time. Ideas come back just before you'd forget them, in interleaved sessions that mix recall, application, and teach-it-back. The orbits you boosted above are exactly the rhythm: each successful recall roughly doubles an idea's safe interval.
The observatory is open
Beyond this door is a spinning world of 165 lit minds. Sophia meets you there — a two-minute conversation finds your starting point, then your first lesson begins.
