Bloom is a one-on-one AI tutor built on Bloom's Taxonomy. Highlight any sentence and ask, and the answer appears in a second or two without breaking your flow. Clip web pages or upload PDFs, papers and long articles to learn from them. Every course lands on a knowledge tree built from about 50,000 Wikipedia entries, and Bloom recommends what to learn next based on what you've studied. Freemium: 1000 free credits on sign-up, paid monthly plans.
