Producing content is a lot of work. We offer a simpler way to scale.

When you’re producing a lot of marketing content, resourcing and cost quickly become a challenge. Content managers, directors of marketing, and agency owners end up editing their team’s work. This keeps you from working on higher-value initiatives.

Businesses that use EditorNinja’s flat-rate on-demand editing services save 3-5 days of effort per month on average and cut their editing costs by 40-60%, which puts thousands of dollars back in their pocket or budget.

Our proprietary technology enables our professional MFA-trained editors to edit your content at scale. Your content gets edited right the first time, without the hassle of finding, hiring, training, firing, and managing editors yourself.

Focus on the process, not the people, of producing great content. Add your request to your queue, and your dedicated editor will take care of it. And scale production up or down at any time according to your needs.


Easily add your documents to your queue via the EditorNinja portal. Your editor(s) work through your queue each day.

Whatever editing your document needs, we can handle it. And we’ll keep working on it until it’s right.

Receive your edited document back to your inbox in just 1-2 business days. Review, publish, and watch your business grow.

Frequently Asked Questions

Frequently Asked Questions

EditorNinja employs  professional editors who work on customer content every business day of the month. If you upload 10 pieces of content, your content will be scheduled out with your editor who will work on one document at a time. The average document takes one business day from the date it enters editing to when it comes back to you ready to publish.

Maximize your editing subscription by keeping your queue full, and you can always add an additional editing lane if you need more output in a given month.

Throughout EditorNinja you’ll see us talk about a “lane.” A lane simply another chunk of words to be edited. We base our pricing on volume of words edited per day.

Our base subscription, one lane, is 20,000 words per month, or 1,000 per working day. If you need more output, you can add additional lanes. Contact us for current pricing on additional lanes.

All of our editors are US-based professional MFA-level editors who have taught writing and editing at the university level.

From dissertations to white papers and blog posts, they’ve edited it all and are trained to edit content to your brand’s specifications.

Plus, they’ll give you feedback on the writing so that both the writing and editing process are easier moving forward.

All EditorNinja plans include copy editing, proofreading, and line editing. You get unlimited requests, unlimited revisions, and a Senior Editor who primarily edits your content. They’re supported by a backup editor who also gets to know your brand.

Unlimited is the perfect plan for in-house teams or agencies producing 6-12 pieces of content per month. You add documents to your queue via the EditorNinja portal, and receive them back via email and the portal after they pass our double QA process. If you need more output, you can always add another lane (or two or three!) to increase how much content is edited per day. 

Pricing starts at $649 per month. Learn more.

Dedicated Editor is the right plan for companies who need an editor who will work within their systems. For a set fee for a set number of hours per week, you can work with an EditorNinja professional editor and get going in days, not months like it takes when hiring on your own. 

Pricing starts at just $1,500 per month. Learn more.

Finally, if you just have a few documents per month (or want to test the service before committing), you can always use our Single Document editing services. All documents are copy edited and proofread to your brief, or MLA style as default. Pricing starts at $.035 per word plus a small administrative fee, and documents are returned in one business day by default. We give a 20% discount for a two business day turnaround.

Get started here.

Our editors can edit any kind of written content. From blog posts to white papers, sales pages to social media content, our editors have edited it all and will make your content do your brand proud.

Please note that our editors are not subject matter experts, and they are not creating brand new content for your brand. But if you need content edited before it’s published, our editors have you covered!

Our editors are professional developmental, line editors, and copy editors, with proofreading skills. They take already written content and make sure it’s clean, adheres to brand guidelines, and is clear in what it’s communicating. Sometimes this involves leaving comments suggesting potential new language when a sentence or paragraph is unclear. Sometimes it’s correcting a lot of commas, capitalization, and rearranging a few paragraphs to make the piece read better.

This said, EditorNinja editors to do not write new copy. They are also not subject matter experts, which means if that’s important to you then you should have an internal expert review copy for correctness either before or after editing.

Within the EditorNinja portal, we ask you to include:

  • – The document type (most common is Blog Post)
  • – A link to the document (ideally a Google Doc)
  • – Word count
  • – A brief containing anything the editor should take into account for this specific document, such as making sure all links work or that no paragraph is longer than 5 sentences.


You should also upload your brand and content guidelines to your Brand Documents so your editor, and any other edited assigned to your content, can access them. 

Every Subscription customer receives:

  • EditorNinja portal access, to upload documents and see your queue as well as your document history.
  • Up to 20,000 words edited per month, or approximately 6-12 documents, per editing lane.
  • One business day turnaround on most documents once they enter editing.
  • A Lead Editor (account manager) and a Senior Editor who are primarily responsible for your content.
  • Ability to upload brand and content guidelines for every site we’re editing for. 

No! With an EditorNinja subscription, we can edit content for as many sites or accounts as you have. Just add each site or account’s brand and content guidelines, and our editors will make sure to follow them.

Just remember that our editors work on your account every business day at a set cadence, so editing for multiple sites can slow down content for each individual site.

If that’s the case and you need more output, you can always add another editing lane to your account.

EditorNinja does not yet support multiple users within an account. It is on our backlog, though!

We do, however, support adding a second email to specific documents so that a second person can be notified when a document has been returned in EditorNinja. That email notification contains a link to the finalized document, so they can access it and continue the document workflow.

As an EditorNinja Subscription customer, you will be assigned a Lead Editor (account manager) and a Senior Editor who is responsible for the majority of your content. While our goal is to have you work with them as much as possible, every Senior Editors is supported by a backup editor to ensure your work keeps moving. This means that from time to time your content may be edited by an editor other than your Senior Editor. Your backup editor has access to your brand and content documents you’ve added to the system, so they’ll always edit to those. And because you can leave feedback for your editor on every document, they’ll listen to feedback and take it into account over time.

If you require an editor who will work directly within your existing systems, let’s discuss finding you a Dedicated Editor.
