FileSeen for ChatGPT

ChatGPT + FileSeen: links that tell you when they are opened.

ChatGPT writes the email. FileSeen gives it a link for the file, and later tells it who opened it.

Setup

Connect FileSeen to ChatGPT

About two minutes.

  1. Step 1

    Create an API key

    In Dashboard → Settings → API keys. A verified email is needed.

  2. Step 2

    Add FileSeen to ChatGPT

    Turn on developer mode in ChatGPT's settings, then create a connector with this URL: https://mcp.fileseen.com/<your key>. Menu names can differ by plan.

  3. Step 3

    Ask

    “Make a FileSeen link for this file” or “Did they open it?”

Files you upload in a ChatGPT chat may not reach connectors. If that happens, give ChatGPT a public download link to the file, or ask it to write the document and use create_tracked_link_from_text.

What your assistant can do

  • create_tracked_link: Turn a file into a FileSeen link to paste into any email or chat.
  • create_tracked_link_from_text: Turn a document the AI wrote (a proposal, a quote) into a PDF link.
  • check_if_seen: Was it opened? How many times, when, and the time on each page.
  • list_my_links: Your links with opens and reading time, for any period.
  • recent_activity: Every recent visit across your links, newest first.
  • get_link_analytics: Everything about one link: readers, pages, drop-off and a daily timeline.
  • compare_links: Which of your documents got the most attention.

Things to ask

  • “Make a FileSeen link for proposal.pdf and write a short email to Ana with it.”
  • “Did Ana open the proposal? Which pages did she read?”
  • “Which of my documents were opened this week?”
  • “Compare my three pitch decks. Which one got read the most?”

FAQ

Questions about FileSeen and ChatGPT

Can ChatGPT send emails with attachments?

ChatGPT can write the email. With FileSeen it puts a link in it instead of an attachment, so there is no size limit and you see when it is opened.

Which ChatGPT plans support it?

Custom connectors need developer mode in ChatGPT. Availability depends on your plan; check ChatGPT's settings.

Does the reader need an account?

No. The link opens in any browser, on a phone or a computer.

Is my API key safe?

Treat it like a password. Anyone with the key, or with a connector URL that contains it, can make links on your account. Revoke it any time in Dashboard → Settings → API keys.

Which files work?

PDF, PowerPoint, Word, Excel, images and more, up to 95 MB. Web pages and ZIP files are not accepted.

Will the assistant say a file was opened when it was not?

It is told to report only what FileSeen returns. Checking a link never counts as an open.
