A tutor that shows its sources
Explanations come from your slides, readings and transcripts, with verified quotes. When your materials don't cover something, it says so — and any general explanation is clearly labelled.
For university & college students
Study smarter from your own course materials.
Proofline turns your lectures, readings and syllabus into cited explanations, practice that sticks and a realistic plan — and helps you write assignments that stay yours.
- Answers cite your materials
- Follows each assignment's AI rules
- Private to you
One loop for every course
Learn it. Practise it. Plan it. Write it.
Everything for a course lives in one place, so what you learn feeds your practice, your plan and your writing.
- 01
Learn
Ask about any lecture, reading or passage. Every answer shows the exact lines it relies on.
- 02
Practise
Questions checked against your sources, timed practice exams and spaced flashcards.
- 03
Plan
Deadlines ranked by weight, a two-week plan within your hours and a 5-minute first step.
- 04
Write
Decode the brief, track requirements and get rubric feedback that never rewrites your work.
Built for how students actually study
Help you can check, not answers you have to trust.
Practice that finds your gaps
Answer first, then see the model answer and the source. Wrong answers go to your mistake notebook and clear when you get them right.
Remember it on exam day
Spaced flashcards with daily limits, so reviews never pile up into an impossible backlog.
A plan that fits your week
Imports your syllabus and calendar, spreads the work across your study hours and reschedules missed tasks without guilt.
Assignments, brief to submission
Requirements checklist, templates, rubric feedback, citation checks and an honest AI-use disclosure.
Study together
Share flashcards, practice sets and meeting notes with classmates, with a clear record of who did what. Assignment drafts stay private to you.

Syllabus, slides, readings or transcripts. Proofline suggests topics and deadlines for you to confirm.
Start a 5-minute session
A short explanation from your materials, then a question to check it stuck.
Academic integrity, built in
Help that respects your course rules.
Set each assignment's AI policy from your course rules. Proofline enforces it on every request and keeps a private log, so your disclosure is accurate.
AI allowed
Every tool is available. Review each suggested change before it reaches the page.
Guidance only
Explanations, questions and feedback — but no rewriting or drafting of your text.
Not permitted
AI switches off for that assignment and its drafts. Your planner and checklists still work.
Proofline is for individual students. Your courses, drafts and progress are private and never reported to a school. Progress reflects your practice answers — it isn't a grade prediction.
