SignNow lets you streamline document workflows directly inside ChatGPT and Claude. Once connected, you can use natural language to work with templates, prefill fields, prepare documents, and keep signing processes moving without constantly switching between tools.

This guide walks through how to connect SignNow in both platforms.

Before you start, make sure you have:

To connect SignNow to Claude, open the Claude website or app.

Go to Customize.

Search for the SignNow connector, then click Connect.

Claude will open the SignNow authorization screen. If you are not already signed in, enter your SignNow credentials. Then click the Grant access to SignNow button and complete the connection.

Once that’s done, SignNow will be available for use inside Claude. You can go to Customize > Connectors > SignNow to review and edit permissions or to Disconnect/Remove the SignNow connector.

To connect SignNow to ChatGPT, start by opening chatgpt.com in your browser and signing in to your account.

Click your profile menu in the lower-left corner, then open Settings.

From there, click Apps, then Advanced Settings, and turn Developer mode on.

Next, click Create app.

A setup window will open where you can configure the app. Here, you can:

A new browser tab will open and take you to the SignNow authorization flow. If you are not already signed in, log in with your SignNow credentials. Then click Grant access to SignNow to authorize ChatGPT to use SignNow on your behalf.

Once setup is complete, open a new chat in ChatGPT, click the + button, and choose SignNow in the More dropdown menu.

You are now ready to use SignNow inside ChatGPT! 🎉

To disconnect the app, refresh it or check further details, go back to Settings > Apps > click the SignNow app.

After setup, the experience is similar in both ChatGPT and Claude.

Once SignNow is connected, you can use natural language to streamline common signing workflows directly in the conversation. For example, you can ask the assistant to list your templates, prepare a document from a template, prefill fields such as dates or names, and get a document ready to send.

A typical workflow might look like this: ask the assistant to find a template, prefill a field like today’s date, generate the document from that template, and then confirm whether you want to send it to a recipient.

This helps reduce manual work, speed up document preparation, and keep workflows moving in one place.

If you do not see the option to create a custom app in ChatGPT, check that Apps and Developer mode are available for your account.

If you do not see the SignNow connector in Claude, confirm that connector access is enabled in your environment.

If authentication fails in either platform, verify that:

If the connection succeeds but actions are limited, review the permissions granted during authorization.
