The difference
A chat answers. A course stays.
Both can explain anything. Only one of them is still there next month.

Why acidity comes first
Before grape names, before regions: acidity is the spine of a wine. It is what makes the second sip follow the first.
Take a cold nine-euro Albariño out of the fridge. The first thing you notice isn't fruit — it's that your mouth waters.

How it works
From a topic to a book on your nightstand
Three moves. The longest one is deciding what you want to learn.
Say what, and for whom
A topic, who it's for, and how deep to go. That's the whole form — the audience does more of the work than you'd think.
Argue with the syllabus
Sapiens plans the modules and their order before writing a word. Reorder, cut, annotate — full lessons are only written once the arc has earned it.
Read it where you read
Every module arrives as a real book — EPUB, PDF, or straight to your Kindle by email. The web reader keeps the argument going; your Kindle keeps the book.
The part that stays
What a chat can never keep
A course is a thing you own: it accumulates your arguments, your practice and your progress — and it leaves with you whenever you want.
Argue with it. That's the point.
Highlight any passage and say what's wrong — too abstract, too long, missing an example. The note sticks to the text, and the next rewrite answers it.
Practice, placed where it belongs
Quizzes, flashcards, glossaries, common mistakes, case studies. Generated with the lesson and dropped at the point in the text where they actually help.
Yours to keep and to take
Every course lives in your library, and leaves it whenever you want — export to PDF or EPUB, or send it straight to your Kindle.
Written in the language you chose
A course's language is set when you create it and never drifts: an English-speaking reader can own a Spanish course, and its lessons, exports and Kindle mail all stay Spanish.
You pay for writing, not for waiting
Credits are spent when a syllabus or a lesson is actually written. Work that fails is refunded automatically — you are never charged for a blank page.
Bring your own agent · MCP
With your own agent, writing is never metered
Sapiens speaks MCP. Connect Claude — or any agent that speaks the protocol — and it reads the same brief Sapiens' own writer would get, writes the syllabus and the lessons itself, and saves them to your library. Your agent brings its own model, so Sapiens never charges per generation: authoring comes with any paid plan — the $19-a-year Agent Pass, or Basic and Pro, which include it. Reading your library is free for everyone.
- No creditsEverything your agent writes
- Plan a syllabus, write every lesson with its practice, rework modules, keep it all in your library, and export to PDF or EPUB. On a paid account, none of it spends a credit.
- CreditsWhat Sapiens does itself
- Generating on our models inside the app, and mailing a finished course to your Kindle — that one sends a real email.

Word of mouth
People who stopped skimming and started learning
“I generate a course, send it to my Kindle, and read it on the train with no screen glare and no tabs. That's the whole loop, and it's the one I actually keep doing.”
“I asked for Kubernetes for someone who already knows Docker. It didn't re-explain containers for three modules. That alone put it ahead of every course I've paid for.”
“The flashcards and the quiz show up in the middle of the lesson, right where I'd already started wondering whether I'd understood. Somebody thought about that.”
“The first lesson was too abstract, so I highlighted the paragraph and said so. The rewrite opened with an example. I've never been able to argue with a course before.”
“I teach in Spanish and read documentation in English. Sapiens is the first tool that let me keep those separate instead of translating everything twice.”
“I built a six-module onboarding course for my team in an evening, exported it to PDF, and nobody guessed how it was written. It reads like I wrote it carefully.”
Placeholder people, real product — these quotes are sample copy, to be replaced with readers of your own.
