Chat With Your PDF
Upload a PDF and ask it questions instead of scrolling for the paragraph you half remember. Answers come from your file, and the free tier is enough to try it.
Ask the document, not a search box
A search box needs the exact word the author used. A question works when you remember what the section was about but not what it was called.
- Answers trace back to the file
- Everything comes from the PDF you uploaded, so you can go back and check the section it came from.
- Follow-up questions keep the thread
- Ask it to shorten an answer, list it as points, or explain a term, without repeating the original question.
- It says when something is not in there
- If your question is outside the document, it tells you rather than filling the gap with something plausible.
How it works
Upload, wait, ask, verify. The last one matters more than people expect.
Upload the PDF
Pick the document you keep scrolling through — a textbook chapter, a paper, a manual, or a set of lecture slides exported to PDF.
Wait for it to process
The file is read and indexed once. After that, questions are answered from it rather than from a general model's memory.
Ask in your own words
You do not need the exact phrase from the document. Ask what you actually want to know and it finds the relevant part.
Check it against the source
Answers come from your file, so you can go back to the section and confirm. Do that on anything you are being marked on.
Why Cortexvia
The document is the point. A model that has not read it is guessing.
Answers from your file, not the internet
It reads the document you uploaded. That is the difference between a study aid and a general chatbot guessing at your syllabus.
Better than Ctrl+F
Search needs the exact word. A question works when you remember the idea but not the term the author used for it.
Free tier handles a short PDF
One chatbot from up to two PDFs is what the free plan allows, at 5 MB and ten pages each. Longer files and more of them need a paid plan.
Student plan
More files, longer documents, and a YouTube link, priced in your local currency.
Questions
What people ask before uploading their first document.
More for students
The same platform, pointed at the rest of your material.
Get started
Start on the free tier with up to two documents and see whether the answers hold up against the source.
Test it on a document you already know. Ask it five questions you can already answer. That tells you in two minutes whether to trust it on the ones you cannot.
