Trajectory turns the chaos of college admissions into a clear, honest plan. Something built around where you actually stand. Most students are flying blind: they don't know if they're on track, which schools are realistic, or what to do this week. Trajectory fixes that. WHERE YOU STAND, HONESTLY See your whole record in one place — GPA, test scores, course rigor, and every activity — and a single honest read on how far along you are. No hype, no false comfort. YOUR REAL CHANCES AT EACH SCHOOL Build your college list and get a grounded estimate for every school, from hard reach to likely, that updates as your record grows. It's honest math on your numbers, not wishful thinking. A PLAN FOR TODAY — AND THE WEEK AHEAD Trajectory breaks the work into bite-sized tasks and lays them out day by day, so you always know the next right move. Connect your calendar and it schedules study sessions around your real free time. PERSONALIZED AI THAT KNOWS WHERE YOU STAND Ask the coach anything and get specific, honest guidance grounded in your actual profile. Generate a per-school report that names your strongest angle and a plan to tailor your application. Build your Common App activities and honors list — with descriptions drafted from your notes. TRACK EVERYTHING THAT COUNTS Log activities with the categories and tiers admissions officers actually think in. Add your courses. Update your numbers. Everything feeds your progress, your chances, and your plan. Trajectory is honest by design. It won't tell you what you want to hear — it tells you where you stand and exactly what to do about it. TRAJECTORY MAX FREE FOR THE FIRST 100 USERS. For students 13 and older. No account, name, or email required to start.
