Dear agency owner,

Your agency is scaling and your challenge is quickly becoming capacity. You can scale writing, but editing is becoming a bottleneck for you.

Writers are editing each other’s content, so you’re trying to find a full time editor. But that’s going to be hard, expensive, and time consuming.

So make the easy decision easy and use EditorNinja to fulfill your capacity until your revenue makes sense to hire full time (but we’re confident that you’ll love our services so much that your new editor will want to keep using us!)

EditorNinja does for editing what content creation platforms have done for content creation by enabling you to scale your content capacity as your client roster and content volume grows.

Our pricing is built to scale with agencies, giving you more volume when you need it and not charging you for it when you don’t. And we’ve worked at and run agencies, so we know what you need in a product to facilitate it.

Grow revenue, reduce overhead, and produce better work with an easy EditorNinja subscription.

  1. Content consistency
  2. Brand adherence
  3. Content structure

EditorNinja - Hire editors for your agency without the painful hiring process.

Why copy editing?

Copy editing occurs during the creation process. Before your document is ready for final proofreading review, you may wish to have it read for correctness and clarity of argument. This is copyediting in a nutshell.

Most copy editing happens in draft form, such as in a Word or Google Doc (or similar depending on type of document, such as PPTX for a presentation). This is so that in-depth edits can be made and comments left for the author to return and make the edits to their own manuscript.

Why Agencies need copy editing

Copy editing is necessary after the initial writing to correct for many common errors including clarity, structure, word usage, and proper citation of sources.

Every document should be copy edited before being published and returned to your client. If it’s not, you’re risking returning copy with typos and errors to your client, which hurts your brand and risks losing the client.

Long story short, as an agency producing content for clients you need EditorNinja because we’re faster, cheaper, and just as good as an in-house editor.

Ninja Edits

Your Ninja works diligently on your editing queue.

Delivered to you

Your documents come back to you ready to go. Like ninjas in the night.


Not if you don’t tell them! EditorNinja is a great replacement for hiring in-house editors or freelancers who may flake out on you. Editing is what we do, and our editors are professionally trained to deliver results.

Your internal agency team will upload content to EditorNinja and then manage returning it back to your client. Your client will never know you didn’t hire someone in-house.

As a content agency, your ability to grow is constrained by your capacity. EditorNinja allows you to scale up your customers because you can always scale up editing capacity.

Your clients also count on you to deliver them content that they can publish and use to grow their business.

When you return subpar content to them, trust breaks and they churn faster than they should.

By using EditorNinja, you will retain your clients longer and can charge them more for the content you’re producing because it’s better than content they could get elsewhere.

EditorNinja does not produce content. We edit the content you are already producing.

If you need content production, we recommend Verblio.

We know that many content firms also use tools like Frase or Surfer SEO to optimize content for SEO.

Our editing does not interfere with these scores. Copy editing and proofreading are focused on the technical aspects of writing, not on if arguments make sense or if you’ve included the right sections to help content rank.

“The difference between good and great is often an extra round of revision. The person who looks things over a second time will appear smarter or more talented, but actually is just polishing things a bit more. Take the time to get it right. Revise it one extra time.” - James Clear, Author
