Anchor new knowledge to what you already know.
Some subjects are too big to memorize twice. Anchor helps you tie every new concept to something you already understand — so each fact has a place to live, and the next one has somewhere to attach. Less re-learning, more compounding.
A learning loop, not a vault.
Anchor
When you add something new, Anchor prompts you to connect it to a concept you already hold. Every card lands attached to scaffolding, never floating on its own.
Reinforce
Spaced repetition strengthens the link between new and known. You don't just recall the fact — you re-walk the path that explains why it's true.
Extend
Once a concept is anchored, it becomes the anchor for the next one. Your understanding compounds: every hour of study makes the next hour faster.
"We don't remember isolated facts. We remember things by the company they keep."
Most study tools treat each fact as a standalone item to be drilled. That's why volume feels punishing: every new card is a new line item with no support beneath it.
Anchor inverts the model. New material is taught in terms of what you already know, then reviewed in a way that keeps the bridge between them intact. Knowledge stops being a list and starts being a structure.
Start building forward.
Create your account, anchor your first concept, and let every study session make the next one easier.

About Us
Anchor is a four-person company. One of us is a sleep-deprived student. The other three are large language models who have never once complained about a 3am study session. Together we make flashcards that don't feel like flashcards — because exactly one of us actually has to use them.
A student who would rather do almost anything than make another flashcard. Started Anchor out of pure spite for her review deck. Fuels the company on iced alani and the quiet rage of someone who has reviewed the same fact one too many times.
Builds the entire app between sips of Ellie's alani. Never sleeps, never asks for equity, occasionally writes a CSS rule so beautiful it makes Tailwind cry. Insists meetings are 'just a quick prompt.'
The thoughtful one. Reads a paragraph of source material and produces a flashcard so well-worded Ellie almost enjoys it. Has strong opinions about em dashes and an unshakeable commitment to nuance. Will gently push back if your question is bad.
Looks at a screenshot of any page and somehow knows every topic on it before you finish blinking. Fast, cheerful, slightly chaotic. Treats every PDF like a personal challenge.
