About this app
Paste an essay and get grade-level feedback on structure, clarity, and argument - feedback that helps you write it, not writing it for you. STUDY PLANS FOR TEST DAY Tell Birdbrain your topics and your test date. It gives you a pretest to find your weak spots, a day-by-day schedule built around them, and quizzes along the way to prove you're improving. STUDY ROOMS Make a room, invite classmates, and work through it together. kAtI sits in every room - she moderates every message and can answer questions for the whole group. KEEP THE STREAK Daily streaks, badges, weekly goals, an activity calendar, and weekly leagues you climb by studying. Send a progress report to a parent, tutor, or teacher whenever you want. BRAIN ROT MODE Flip one switch and the whole app starts talking like your group chat. Same study tools, worse vocabulary. Built for middle school, high school, and college.
