For students and researchers
Compare research papers in one table
Upload two or more papers as PDFs. FileAI builds a table of their methods, data, findings and limitations. Every cell links to the page it came from, so you can check it.
Free plan: 10 documents and about 40 questions a month. No card needed.
A literature review starts with a table
When you write a literature review, you read many papers. Then you put them side by side. How did each study work? Who took part? What did it find? What could be wrong with it?
Making that table by hand takes hours. FileAI makes a first draft in minutes. Select your papers and ask for a comparison table. Each cell has a page link. Then you check the cells, fix them and add your own notes.
A real example: two papers compared
We asked the same four questions of two open-access papers about retrieval practice. This is a study method where you test yourself instead of reading again. Choose a page link to open the paper at that page.

|---|---|---|
| Methods |
Study in children
Three experiments involved 88 fourth-grade children. p. 3 Children restudied some words and recalled others using category clues and starting letters, p. 2 then took recall or recognition tests. p. 2 |
Study in university students
Experiment 1 randomly assigned students to six groups, comparing repeated study, problem-solving, and completing missing steps. p. 3 Across three experiments, researchers varied test difficulty, material difficulty, and feedback timing. p. 8 |
| Data |
Study in children
The study used 88 fourth-grade children from four classrooms, averaging 10 years old. p. 3 Experiments 1 and 2 each included 40 children; Experiment 3 included 42. p. 3 p. 3 |
Study in university students
Experiment 1 enrolled 120 Minnan Normal University students in six groups of 20. p. 3 Experiment 2 enrolled 120 students from the same university; Experiment 3 enrolled 80 in four groups of 20. p. 5 p. 6 |
| Findings |
Study in children
Fourth graders recalled more words after recall practice than repeated study: 55% versus 44%, and 42% versus 28%. p. 4 Recognition also improved; benefits were similar across reading comprehension and processing speed levels. p. 5 p. 7 |
Study in university students
Across three experiments, solving problems after studying examples showed no advantage over restudying examples. p. 8 In Experiment 1, completing missing steps required less mental effort than solving whole problems. p. 4 |
| Limitations |
Study in children
More children and a wider range of scores might reveal differences in retrieval practice benefits. p. 7 The experiments did not directly test competing explanations for why retrieval practice helps. p. 7 |
Study in university students
The learning phase may have been too short, and feedback’s effect remains unclear. p. 8 p. 8 Knowledge types and learning materials lack clear definitions and numerical measures. p. 9 |

How it works
-
1
Upload your papers
Add two or more papers as PDFs with selectable text. Select them together in your workspace.
-
2
Ask for a table
Type: "Compare the methods, data, findings and limitations of these papers in a table." Type it in your language if you like.
-
3
Check each cell
Every cell has a source number. Click it to open the page it came from. Fix the cell if the paper says something different.
Things you can ask
Ask about one paper or about all of them. A few examples:
- Compare the methods of these papers in a table.
- How many people took part in each study?
- Where do these papers disagree?
- What limitations do the authors of each paper mention?
- Which statistical test did each paper use?
- Write one sentence about the main finding of each paper.
- Which paper has the larger sample, and how large is it?
- What do the authors say should be studied next?
Made so you can check it
A comparison is only useful if it is right. So every cell shows where it came from.
Every cell links to its page
Click a source number to see the page in the paper. In PDFs, the sentence is highlighted.
Honest when a paper is silent
If a paper names no limitations, FileAI says so. It does not make some up.
Ask in your language
Type your request in the language you know best and the answer comes back in it. The buttons write in the language of your papers. Quoted text stays as the paper wrote it.
Two papers or many
Select the papers you want to compare. The free plan holds 10 documents.
Private
Your files are stored privately and never used to train AI. Delete a file and its copies go too.
The papers you already have
PDFs with selectable text, Word and more. Scanned PDFs aren't supported yet.
Frequently asked questions
More in the FAQ, or read where your files go.
- How do I compare research papers with AI?
- Upload the papers to FileAI, select them together and ask for a comparison table of their methods, data, findings and limitations. Each cell links to the page it came from.
- Can FileAI make a literature review comparison table?
- Yes, as a first draft. You get one column for each paper and one row for each point, such as methods or limitations. Check each cell against its page, then edit the table for your own review.
- Is the information in the table correct?
- FileAI uses only the text of your papers and shows the page for each cell. AI can still make mistakes, so open the page and check before you rely on a cell.
- Will FileAI write my references?
- No. FileAI shows you the page in the paper. You still cite the papers yourself, in the style your school or journal asks for.
- Does it work in my language?
- Yes, when you type your request. Write it in the language you know best and the answer comes back in it, even if your papers are in another language. The one-click buttons write in the language of your papers. Quoted text stays as the paper wrote it.
- Can I use scanned papers?
- Not yet. Use PDFs with selectable text. If you can select and copy the words in the PDF, it should work.
- How much does it cost?
- You can start free with 10 documents and about 40 questions a month, no card needed. Pro is US$19 a month for more files and questions. Prices in US dollars (USD). There is a 14-day money-back guarantee.
