Feature comparison
| Feature | StudyInk | Khan Academy |
|---|---|---|
| Core teaching method | An AI tutor (INKY) that uses your lesson notes and study plan to explain concepts, then assigns targeted SAT practice based on your performance. | Short recorded video lessons followed by auto-graded exercises; you advance by reaching mastery on each skill. |
| SAT preparation | SAT practice questions, with diagnostics, timed sections, and AI essay grading. | Official Digital SAT Prep, built with College Board and using official practice questions. It covers every SAT skill with videos, full-length practice tests, and a personalized study plan. |
| AI tutor | INKY chat explains answers, grades essays and free-response questions, and turns your YouTube and PDF materials into lessons. | No built-in AI tutor for learners. Khanmigo is a separate, paid product (see our Khanmigo comparison). |
| Collaboration | Study groups with shared study plans and a real-time collaborative whiteboard with a graphing calculator. | Largely solo. Classroom and teacher dashboards exist, but there are no peer study groups or live co-working tools. |
| Accountability features | Streaks, leaderboards, real-time question duels, challenges, and badges keep you practicing consistently. | Progress tracking and mastery dashboards for self-paced learning, but no social or competitive motivators. |
| Essay and free-response grading | INKY grades essays and free-response questions and explains where you lost points. | No essay or free-response grading. Feedback is limited to multiple-choice and auto-graded exercises. |
| Math tools | A graphing calculator lives on the collaborative whiteboard, so your study group can work through problems together. | Interactive math exercises with hints, but no shared whiteboard or calculator for group work. |
| Price | Free, including INK credits for premium AI actions. INK is currently free and just helps us keep AI costs in check. No subscription. | Completely free for learners, supported by philanthropic funding. |
| Best for | Students preparing for a specific exam who want adaptive SAT practice, an AI tutor, and peer accountability in one place. | Self-paced learners exploring any subject, and teachers managing classroom mastery. |
