Can you send a fax with ChatGPT?

Yes: you add mcpfax to ChatGPT as an app (Settings → Apps → Advanced settings → Developer mode, from ChatGPT Plus on the web). ChatGPT then faxes your document after showing the price and getting your confirmation, from €1.00 per fax.

Video transcript

Yes, you can fax straight from ChatGPT, using mcpfax as an app. This works from ChatGPT Plus upwards, on the web. Let me show you how to set it up and how to use it. In ChatGPT, open Settings, then Apps and the advanced settings. Turn on developer mode and create an app for mcpfax. You'll find all the details you need in our setup guide. In the chat, tap the plus, choose developer mode and activate mcpfax. From now on, ChatGPT can send faxes for you. Attach the document and give the fax number. ChatGPT shows you the document, the number, the pages and the price. Because sending is a write action, you have to confirm it explicitly. Only after your yes does the fax go out. You receive the transmission report by email. You'll find the link to mcpfax in the description. Prefer Claude? It works just the same, including in the app on your phone.
