Your study companion, named for a scientist.
Named in tribute to Rosalind Franklin, whose groundbreaking research helped reveal the structure of DNA, Rosalind is your personal AI study companion.
Who Rosalind is
Curious by nature, rigorous in her reasoning, and never satisfied with an answer you don’t truly understand, Rosalind is here to help you think like a scientist.
She’ll challenge your assumptions, guide you through difficult concepts, and help you discover the answers for yourself.
Because knowing the right answer is important. Understanding why it’s right is what makes it stick.
What she does today
When you write an answer from memory and flip a card, Rosalind reads what you wrote, compares it with the card’s key concepts, and grades it: knew it, partly there, or not this time. She tells you what you got right and exactly what was missing. If you think she got it wrong, tap Dispute and we’ll review the card.
Why we named her Rosalind
Rosalind Franklin (1920–1958) was a British chemist and X-ray crystallographer. At King’s College London in 1952, she and her student Raymond Gosling produced Photo 51, the X-ray diffraction image of DNA that revealed its helical structure. Her images and measurements were shown to James Watson and Francis Crick without her knowledge, and they became central to the double-helix model the pair published in 1953.
Franklin died of ovarian cancer in 1958, at 37. Four years later, Watson, Crick and Maurice Wilkins received the Nobel Prize for the structure of DNA. The Nobel is not awarded after death, and for decades her part in the discovery went largely unrecognized. She also did important work on the structure of coal and of viruses.
We named our study companion after her to honor that work, and the credit she was owed.
