OneFile is a free tool that merges your course materials into a single file. Upload that one file to ChatGPT, Claude, or any AI, and you skip the 3-file daily cap on ChatGPT Free and the 10-files-per-message cap on Plus.
OneFile is the tool. ChatGPT, Claude, and Gemini are where you send the combined file. No account. No trial.
Six concrete workflows. Pick the one that matches what you're stuck on this week.
Combine every textbook chapter, lecture slide, and study guide into one upload. Ask ChatGPT to generate practice questions, explain weak spots, or build a study plan that covers everything you actually need to know.
Try this prompt
"Quiz me on chapters 3 to 7 of my textbook and flag every topic I get wrong."
Upload your assignment brief, rubric, all source materials, and class notes together. ChatGPT can outline, cite, and structure your arguments while staying anchored to the exact sources your professor expects.
Try this prompt
"Outline a 2000-word essay using the rubric and these 8 sources. Match the citation style in my class handout."
Drop in all lecture slides plus your handwritten notes and readings for the week. Ask ChatGPT to fill gaps, explain confusing concepts, or summarize across the whole week instead of one lecture at a time.
Try this prompt
"I missed Tuesday's lecture. Using these slides and last week's notes, explain what I need to know for the midterm."
Combine the textbook chapter, the problem set, and your worked solutions so far. ChatGPT can check your work, explain mistakes, and walk through methods, not just give you the answer.
Try this prompt
"Here's the chapter, the problem set, and my attempt at #4. Where did I go wrong, and how do I fix the approach?"
Upload every chapter of your thesis at once instead of pasting them one at a time. ChatGPT can check argument flow across chapters, find contradictions, and suggest revisions with the full document in context.
Try this prompt
"Read all 5 chapters of my thesis. Where do my arguments contradict each other? What's missing from chapter 3?"
Pull every teammate's draft, every meeting note, and the project brief into one prompt. ChatGPT can flag inconsistencies, merge sections, and write the final summary without you copy-pasting for an hour.
Try this prompt
"Merge these 4 teammates' sections into one cohesive report. Flag where we contradict each other."
Four steps. One minute. Free.
Lectures, readings, notes, slides. OneFile skips images and binary junk.
