What it does
You read something useful online. You think "I should remember this." Then you don't make the flashcard because it's too much friction. Klarrity fixes that. Highlight any text on any webpage → we generate clean Q&A flashcards → export directly to Anki, Quizlet, Notion, or Obsidian. No tab switching. No copy-paste. No manual formatting. Capture knowledge in the moment while you still understand it. Your study tools stay the same — Klarrity just feeds them faster. $50/year. Unlimited cards.
