Free Chrome extension
Upload files ChatGPT says are too big
ChatGPT refuses long documents, or takes them and quietly reads only the first few pages. FileUploadGPT splits your file into pieces it will accept and sends them in for you, in order, with the instructions that stop it answering early.
Your file is read inside your own browser. Nothing is uploaded to us.
What you get
Free, with no account
No sign-up, no email, no payment, no trial that ends.
Your file never leaves your browser
It is read on your own machine and typed into ChatGPT. We receive nothing.
Nothing is tracked
No analytics inside the extension, no history, no profile of what you upload.
Open about what it cannot do
It will not help with video, audio or scanned pages, and the guides say so.
What is stopping you
Four different limits produce four different symptoms, and the fix is different for each. Find yours.

Stop cutting documents up by hand
Splitting a long file into forty pastes works, until the one you skip is the one that mattered. This does the same thing without the place-keeping.
