Questions
Is StudySort free?
Yes. Every study guide and every tool is free and needs no account. The note organiser is free for 3 runs a day per browser, because each run costs money to process.
Which exam boards do the guides follow?
The guides cover the content most UK exam boards share for GCSE and A-Level. StudySort is not affiliated with AQA, Pearson Edexcel, OCR, WJEC or any other board, so always check your own board's specification for exact wording and required practicals.
Who writes the guides?
The guides were drafted with the help of AI models and structured around exam topics: definitions, a diagram, flashcards and questions with marking points. AI can get things wrong. If you spot a mistake, please report it so it can be fixed.
What happens to the notes I paste in?
They are sent to an AI model to be organised and are not stored on our server. The organised version is saved in your own browser, so it stays on that device and disappears if you clear your browser data.
Can I use it for university?
The ready-made guides are written for GCSE and A-Level. The note organiser works with any notes, including university lectures, but check its output against your course material.
Does StudySort schedule my reviews like Anki?
No. It gives you the content to revise from. To plan when to come back to each topic, use the free spaced repetition planner.
Pick one topic you keep putting off.
Read the guide, do the questions, mark yourself. It takes about twenty minutes.
