What a ChatGPT file uploader extension actually does

We make one, so weigh this accordingly. It is still worth writing down what this category can and cannot do, because several products in it imply capabilities that do not exist.

What cannot be done, by anyone

Some claims are worth recognising as impossible rather than merely doubtful.

Raising the file size limit. 512 MB is enforced by OpenAI's servers. A browser extension has no access to that decision.

Raising the length cap. 2 million tokens likewise. Nothing installed locally changes how much text ChatGPT can hold.

Raising the daily or rolling upload caps. 3 file uploads per day on Free, 80 files every 3 hours generally. Server side, both.

Making ChatGPT read a scanned PDF. Every plan except Enterprise discards images from documents. An extension cannot change what happens after the content arrives.

If a listing suggests otherwise, that is the point to stop reading it.

What can be done

The workaround is not secret, and there is no reason for a product in this space to pretend it is.

You can do all of it by hand: convert the document to text, cut it into pieces, tell ChatGPT that several parts are coming and to hold its answer, then paste them in order.

An extension does that reliably. The value is entirely in the reliability, because the manual version fails in ways you do not notice: a chunk pasted twice, one skipped, one silently truncated by the paste, or the hold-your-answer instruction forgotten so ChatGPT summarises part one.

Judging one before you install it

1. Read the permissions on the store listing

   A ChatGPT tool needs chatgpt.com and chat.openai.com. If it asks to read and change data on all websites, ask why, because it has no business on your bank's site.

2. Find out where your content goes

   Some process everything locally. Others send it to their own servers, which may be fine and may be exactly what you cannot do with work material. The privacy policy should say. If it does not, that is your answer.

3. Check when it was last updated

   ChatGPT's interface changes often, and anything in this category breaks when it does. An extension untouched for a year is probably broken.

4. Check there is a real developer behind it

   A website, a support address, somewhere to report a break. This category needs maintenance more than most.

When you do not need one

Genuinely worth considering before installing anything.

If you rarely hit the limit. Splitting a document by hand three times a year is faster than installing, learning and maintaining a tool.

If your documents are short. Most are. If yours upload fine today, there is no problem to solve.

If your problem is scans. No extension helps. You need OCR, and after that you may not need anything else.

If your problem is video or audio. Neither is among the supported upload types. Transcribe first, and a transcript is usually short enough to need nothing further.

What ours does, plainly

FileUploadGPT reads the file in your browser, splits the text into pieces ChatGPT accepts, sends the wait-for-all-parts instruction, then feeds the parts in order.

Permissions: chatgpt.com and chat.openai.com. Nothing else.

Your file: read in your browser. There is no server of ours for it to reach.

Cost: nothing, with no account and no paid tier.

The honest summary of the category

These tools remove tedium. They do not remove limits, and the ones implying otherwise are worth avoiding on that basis alone, because a product misdescribing what it does in its listing is unlikely to be more careful with your documents.
