Frequently Asked Questions

Unlimited simply means you can give us as much content as you have, and we’ll tackle it. Flat-rate means you’ll never get a surprise bill, because you pay one flat rate.

EditorNinja employs professional editors who work on customer content every business day of the month. 

Our pricing is based on your volume, depth of editing, and document turnaround needs.

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. 

If you buy a balance of words, reload that whenever you run low.

Every EditorNinja customer receives:

  • EditorNinja portal access, to upload documents and see your queue as well as your document history.
  • One to two business day turnaround on 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. 

Throughout EditorNinja you’ll see us talk about a “lane.” A lane simply another document per day of editing output. We base our pricing on number of documents and words edited per day.

All documents for Word Bundle customers have a maximum 2 business day turnaround. Shorter documents come back the next day!

Yes we can! All In-Depth and Fully Managed subscribers can add content generated via AI to their editing queue.

We do recommend that someone at your company review the content before it’s sent to us, to ensure brand voice and formatting. We do not generate new content using prompts.

AI-generated content takes longer to edit than human-written content, so these requests do take longer to come back for review.

Our editors can edit any kind of written content, though we specialize in marketing content. We most often edit blog posts, white papers, and ebooks.

Please note that our editors are not subject matter experts, and they are not creating brand new content for your brand. But if you have the writing covered and need the confidence that professional editing brings, our editors have you covered!

Our editors are professional developmental and copy editors who also proofread. 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 it read clearer.

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.

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.

You do not, but you can!

With an EditorNinja account, we’ll edit content for as many sites or accounts as you have.  Just add each site or account’s brand and content guidelines as well as examples of content they or you have already produced, and our editors will make sure to follow them.

If you need to pay by account, we support that as well. Just mention this on your Intro Call and we can discuss how it works.

Absolutely. We recognize that agencies have a unique business model and often need to bill per customer, or attach a service like EditorNinja to a specific account.

Most agencies will either get a subscription per customer, or buy a bundle of words to use for that customer over time. We’re flexible on word counts and daily volumes based on your needs.

Schedule a call to discuss how this best works for you.

You sure can! Every editing subscription account gives you unlimited teammate accounts.

You can also add a second email to individual documents so that a second person can be notified when a document has been returned. That email notification contains a link to the finalized document so they can access it and continue the document workflow.

All EditorNinja customers are assigned an Account Manager and a Senior “dedicated” Editor who is responsible for your account. 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.

Yes, we do!

If you sign up to a subscription, add documents and give us feedback on our editing work, and we’re still not able to make you happy, we’ll happily refund your first month of service.

Exclusions apply.
