Can ChatGPT send a fax?

Yes, with a connector. ChatGPT can’t dial a fax line by itself, but with the Dimefax connector added it prepares the fax and gives you a link to check it and pay.

Can Claude send a fax?

Yes. Add Dimefax as a custom connector with the address https://api.dimefax.com/mcp, then ask Claude to fax a document.

Does the AI pay for the fax?

No. You always open the link, see the fax and pay yourself, or use page credits you already have. Nothing is sent before that.

Do I need a Dimefax account first?

No. The email you use at checkout becomes your account, so the page credits you don’t use are there next time.

Is it safe to send private documents this way?

The AI app sees the document as well as Dimefax. For something sensitive, use dimefax.com/send directly instead.

How to send a fax with AI (Claude, ChatGPT and others)

What it looks like

You: “Fax this referral to Dr. Lee at 503-555-0147,” with the document attached, or ask the assistant to write the letter.
The assistant prepares the fax with Dimefax and gives you a link.
You open the link, see the fax and the page count, and pay with Apple Pay, Google Pay or a card. If you already have Dimefax page credits, use those instead.
It sends right away. Ask the assistant “did my fax go through?” and it checks.

The assistant never pays for you and can’t send anything until you’ve checked the fax and paid. On the web, page credits come in packs of 50 for $4.99 or 200 for $19.99, 10¢ a page either way. Each card payment has a fixed fee, so the smallest web pack is 50 page credits; the Dimefax iPhone app sells 10 for $0.99. Credits you don’t use stay in your account and last as long as you fax once a year.

Add Dimefax to Claude

In Claude, open Settings, find Connectors, and add a custom connector with this address:

https://api.dimefax.com/mcp

No sign-in is needed. Menu names change from time to time; if you can’t find it, search Claude’s help for “custom connector.”

Fax often? Connect your account

Use this address instead, and Claude sends from your page credits right away, with no link to open each time:

https://api.dimefax.com/mcp/account

When you add it, a Dimefax page opens in your browser: sign in with a 4-digit code we email you, and choose Allow. Claude can then send faxes from your page credits, check how they went, list your faxes and see your balance. It can’t buy page credits or open faxes you receive, and it’s asked to check with you before each fax. If you run out of page credits, it gives you a link to buy more. Disconnect it any time on Your faxes.

Add Dimefax to Claude Code or another coding tool

In Claude Code, run:

claude mcp add --transport http faxwell https://api.dimefax.com/mcp

To send from your page credits, use https://api.dimefax.com/mcp/account instead; your browser opens once to sign in. Other tools that support MCP servers over HTTP (Cursor, for example) take either address in their MCP settings.

ChatGPT and other assistants

Dimefax is a standard MCP server, the common way to plug a service into an AI app. Where your plan allows custom connectors or apps, add one with the address above. Where it doesn’t, the assistant can still point you to dimefax.com/send, which takes about a minute.

What the assistant can send

A PDF, PNG or JPEG you give it, or a link to one.
A letter it writes for you: Dimefax sets the text on letter-size pages.
If your app can’t pass the file along, the link lets you add the document yourself.

Privacy

The document goes through your AI app before it reaches Dimefax, so the AI company has it too, under that app’s privacy terms. Dimefax keeps an unpaid fax for 24 hours, then deletes it. For a sensitive document you’d rather not share with an AI app, use the web page directly.
