Prefilled message links

Overview

You can create links to Ninja that automatically prefill a message in the text input. This is useful for:

Sharing a task prompt with a colleague
Embedding contextual links in emails, docs, or internal tools
Creating quick-action buttons that start a specific workflow

The format is identical to ChatGPT’s ?q= parameter:

https://ninja.new/?q=Your+message+here

How it works

When a user opens a Ninja link with a ?q= query parameter, the message is automatically placed in the text input so they can review it before submitting.

URL format

https://ninja.new/?q={URL-encoded message}

The message must be percent-encoded. Spaces can be encoded as %20 or +.

Examples

Link	Message
`https://ninja.new/?q=Connect%20my%20Shopify%20store`	Connect my Shopify store
`https://ninja.new/?q=Write+a+product+description+for+my+new+sneakers`	Write a product description for my new sneakers
`https://ninja.new/?q=Analyze%20my%20top%2010%20selling%20products`	Analyze my top 10 selling products

Building links in JavaScript

const message = 'Help me set up Google Ads for my store';
const url = `https://ninja.new/?q=${encodeURIComponent(message)}`;

Link builder

Use this tool to generate a prefilled Ninja link:

The user must be logged in to Ninja to submit the message. If they are not logged in, they will be redirected to the login page first.
