AI agrees with you. A tutor challenges you.
Winda reads your material with you, then does what a tutor does: it quizzes you as you read, remembers what you miss, and asks again just when you're about to forget.
The spacing effect is one of the most robust findings in memory research: reviews spread out over time produce far stronger retention than the same reviews massed together — yet most study habits ignore it entirely.
The reason turns out to be retrieval. Each time you pull a fact back out of memory, just before you would have forgotten it…
According to the passage, what makes memories last?
Pick an answer to see when Winda would ask it again.
That's the spacing effect — exactly how Winda plans your reviews.
Not this one. Miss a question and it comes back sooner, not later.

What your tutor does
Bring anything you're studying — it teaches as you read, and keeps testing you until it sticks.
Bring what you're studying
Web pages, PDFs, slides, YouTube — even photos of your notes. If you're learning from it, hand it over.
Learn more 02It teaches as you read
Ask questions, get annotations and translations — or turn a chapter into a Socratic lesson that pushes back on your answers.
Learn more 03It keeps testing you
Questions grow out of what you read — multiple choice, cloze, Q&A — and each review lands just when you'd start to forget.

A tutor who won't take “got it” for an answer
The questions come from your material. Once one joins your reviews, how you answer decides when you see it again.
Generated for you
Select a passage, a chat, or the whole source — AI writes the questions, so you never start from scratch
Yours to review and edit
Every question is yours to rewrite or delete before you add it to your reviews
Spaced further every time
Answer it well and the gap grows; miss it and it comes back sooner

Remembering isn't willpower. It's scheduling.
Each card comes back right before you'd forget it:
Why Winda
Any AI can answer you — only a tutor tests you
AI notebooks & chat
AI notebooks answer while your sources are open, so the understanding lives in the chat, not in you.
Winda turns those same sources into questions and keeps asking until you can answer without them.
Anki & flashcard apps
Anki schedules reliably, but leaves every card for you to write by hand.
Winda writes the cards as you read, source attached, on the same proven schedule.
Read-it-later apps
Read-it-later apps get you to the end of the article, and stop there.
Winda reads it with you, then quizzes you on it and schedules the review, so it stays.
Question banks
Question banks drill a standard syllabus, not the material in front of you.
Winda builds questions from your own sources and your misses, each linked to its page.
Learners are keeping what they read
“I read the same papers I always did — the difference is I can still explain them a month later.”
Sandy LiPhD student, University of Chicago“Winda turned my CFA reading list into a review schedule. I stopped re-reading chapters out of anxiety.”
Ethan MillerCFA candidate“Cards from YouTube videos felt like a gimmick until my vocabulary reviews started writing themselves.”

Frequently asked questions
Tools like NotebookLM answer questions about your sources, and stop there. Winda reads with you too — but its job is retention: it turns the material into questions, schedules reviews along the forgetting curve, and keeps testing you until you can answer without looking.
