Atticus vs Vellum: A Side-by-Side Comparison [2022]

For a long time, Vellum has been arguably the best formatting software for authors. However, it has always had problems due to it only working for Mac, and is very expensive. Furthermore, Vellum has publicly said that they do not intend to make a PC version and point authors to either buy a Mac, or use a Mac in Cloud paid service in order to use them.

But then entered Atticus, a software that not only claims to be as good as Vellum, but works on all operating systems and is much cheaper.

So, this leaves people with the question – is Atticus really that good and how does it actually compare to Vellum?

So, in order to answer this, I'll be doing a side-by-side comparison and will discuss the pros and cons to each and see if Atticus can replace Vellum.

Let’s dive in and take a look.

In this article, you will learn:
  1. Which is better, Atticus or Vellum?
  2. A side-by-side comparison of each platform’s features
  3. An upcoming look at future features for Atticus

Disclosure: In this article I use affiliate links. They don’t cost you anything extra and they do not affect my decision between Atticus and Vellum. But it all goes to the Kindlepreneur coffee fund, which I greatly appreciate. Also, Atticus is owned by Dave Chesson, also the owner of Kindlepreneur, though I have done my best to objectively evaluate Vellum and Atticus against each other.

Vellum vs Atticus: A List of Features

In order to quickly see how the two compare, let's start by doing a side-by-side comparison of the two. Then, once that's complete, I'll do into a full dive into each of the most important features to better explain each. With that, here is a Vellum vs Atticus comparison table:

Major Features

Not all the features in a product are that relevant to most authors, which is why I wanted to start with a list of major features. These are aspects of each software that I consider essential, or nearly so, to the point that the lack of one could be considered a deal breaker. 

When comparing Atticus to Vellum, I considered the following to be the most significant features:

  1. Pricing
  2. Platform Availability
  3. Ease of Use
  4. Online and Offline Use
  5. The Word Processor Itself
  6. Exporting/Importing Options
  7. A Theme Builder
  8. The Support Team

Let’s break down each of these individually:

1. Pricing

pricing for Vellum and Atticus

Vellum is priced at $199.99 for the ebook-only package, and $249.99 if you want to do paperback formatting as well. As a prior user of Vellum, I can tell you that you definitely want the paperback package to make it worth your while. 

Atticus is priced at a universal price of $147, and it includes paperback capabilities, meaning you get the same package for more than $100 less.

Is there a free version?

For Vellum, you can download their software for free and play around with it, but if you want to actually export an ebook or paperback PDF, you’ll need to pay. 

For Atticus, there is not a free version, but there is a 30-day return policy, so if you try it out and decide it’s not right for you, you can easily get a refund. Some ask, why not do what Vellum does and offer it free until someone exports. However, the reason why Atticus doesn't do this is because, unlike Vellum, Atticus offers a full writing capability and will soon offer collaboration, plotting and more inside of it, making it a full suite of capabilities for authors.

In short, Atticus is the clear winner when it comes to price. But does it offer the same value? You’ll have to keep reading to find out.

Point +1: Atticus

2. What Computers Do They Work On?

atticus and vellum number of platforms in comparison

This is the deal breaker, the area where Atticus steps up as the clear favorite.

Vellum is available for Mac only and while you can pay extra to use a service called Mac in Cloud in order to use Vellum on a PC, it's slow, costly and a pain.

Other than that, that’s it. Period. No exceptions. Do not pass go. Do not collect $200. Turns out Vellum is built on a coding language that only works on Mac computers, meaning they would have to build it from the ground up to create a Windows version, and it’s clear from their own website that this is not a priority for them.

Atticus, on the other hand, is available via every platform under the sun, and not just because it’s accessible via a web browser. Using a progressive web app (PWA), you’re able to use Atticus on:

  • Windows
  • Mac
  • Linux
  • Chromebooks

That’s a lot of devices. Also because it works downloaded, or in browser, you can use it on multiple computers (your desktop, or laptop while traveling). In short, it’s the clear superior when it comes to availability to the widest possible network of authors.

Point +1: Atticus

3. Ease of Use Comparison

Ease of use is one of those metrics that are hard to quantify in a way that is measurable. But I’ll do my best here. 

Vellum has long been known to be easiest book formatting software to use, with zero need for complicated instructions, courses, or anything like that. It’s relatively intuitive to find anything you need to find. The downside to this is that it lacks the kind of advanced features one might find in a program like Adobe Indesign. That said, Vellum was not built to be either of those programs, nor to appeal to their audiences. 

Atticus is equally simple, with all of its features found with the same minimal number of clicks as Vellum. While Atticus aspires to have far more features than Vellum, so far its done a great job in not cluttering the system but giving advanced users ways to make their books look unique – something I'll cover in a bit.

But all in all, they are very similar in their operations and thus, their ease of use.

Point +1: Both

4. Online and Offline Use

There are a couple of questions I ask at when determining which is superior in online and offline use:

  1. Is it backed up to the cloud?
  2. Can I use an in-browser version?
  3. Can I use it offline with no Internet connection?

For Atticus, here are the answers

  1. Yes, Atticus backs everything up to the cloud automatically, and with an auto save feature – this means that if something ever happens to your computer, like spilling coffee on it, your computer might be toast, but your works are completely safe.
  2. Yes, there is an in-browser version, so you can access it from anywhere as long as you have an Internet connection. This means that you can use it on your home computer or on your laptop or Chromebook when you're on the go.
  3. Yes, you can use it offline if the program is installed on your computer (note: an Internet connection will need to be restored if you want any work performed while offline to be synced with the cloud). The only time you'll need internet connection with Atticus though is to either initially log in, when you upload a new doc, export a book, or when you are using a future feature of Atticus – collaboration.

For Vellum, here are the answers to the same questions.

  1. Limited. You can use a third party system to save Vellum files in the cloud but this is not a native capability.
  2. No, there is no in-browser version. Plus your license only works for two computers so you can't use it on more computers (a work or travel laptop for example) without having to pay for it again.
  3. Yes, the program works offline and does not need an Internet connection, and this is the only way that it functions

As you can see by the answers here, Atticus is once again the clear winner since you get the best of both worlds with some slight limitations:

Point +1: Atticus

atticus and vellum word processor in comparison

Of course, we should look at the word processor itself to see what capabilities it has when you’re inputting your book into that space.

I would say that this is a tie between Vellum and Atticus, because they both have roughly the same number of features in the word processor. If I had to give one an edge, it would be Atticus, because it’s specifically designed to be a word processor. 

That said, Atticus still has a number of features to add to its word processor before it’s truly superior to Vellum’s, so for now I’m calling it even. The number of features found in each includes:

  1. In-app spell check
  2. Endnotes (note: Vellum only saves endnotes and does not include footnotes)
  3. Chapter splitting/merging
  4. Word count
  5. Adding images
  6. Style buttons (bold/italics/links/etc.)

Point +1: Both

6. Exporting/Importing Options

Though perhaps often overlooked, export and import options are important for reasons I’ll get into below.


Both programs export to an EPUB and PDF format. These are both the most common formats used in ebook and print formats.

However, Atticus also exports as a DOCX file, which makes it incredibly easy to collaborate with editors, audiobook narrators, beta readers, etc. Vellum does not support this feature.

That said, Vellum also exports to MOBI, which Atticus is working on. And while Amazon doesn't require MOBI anymore, it's still useful to have that file for certain scenarios, such as when giving the right file type to a beta or ARC reader. So I'm giving this point to Vellum.

That said, even if you can't export to MOBI yet in Atticus, you can still use a program like Calibre to convert from EPUB to MOBI.

Point +1: Vellum


When creating a new book, you might already have a DOCX file, an EPUB file, or other version of your manuscript that you want to import into Atticus or Vellum. So what formats does it accept.?

Vellum will only import a DOCX file, whereas Atticus current supports DOCX and RTF, MOBI, and EPUB with more on the way.

Point +1: Atticus

7. Book Previewer

atticus and vellum device previewer in comparison

Both Vellum and Atticus feature a book previewer.

In Atticus, the previewer lets you tab from one chapter to another, but does not feature pagination like Vellum.

Vellum has pagination, which makes it a better simulation of what the book looks like on each device. And this means that it currently has the advantage in this area.

However, Atticus will soon be adding an advanced previewer that will not only give it pagination capability, but will also be more extensive than Vellum.

Point +1: Vellum

8. Available Chapter Themes

Vellum has eight different chapter themes to use in your books.

Atticus not only has more than double this number, but is continually adding more and features a custom chapter theme builder (see next section).

This means that your chapter headers can look any way you want them too, and you can set your book or series apart from other authors using the same software. Additionally, Atticus allows for full page image bleeds, and the themes themselves look great and match more genres than Vellum.

In short, Atticus is the clear winner here.

Point +1: Atticus

9. Custom Chapter Theme Builder

Long-time users of Vellum have probably never heard of a theme builder because…Vellum doesn’t have one. One of the biggest complaints with Vellum is that with a limited number of 8 themes, you can always tell whether a book was created with Vellum because they all look the same. However, Vellum has announced that hopefully by end of December they will have something like this, which they are currently testing. But a quarter of a year is not considered “soon.”

Yet, in its infancy, Atticus has already delivered on a Custom Chapter builder making Atticus books unique and giving their users the ability to truly make beautiful books.

With Atticus' theme builder, you can either start with an existing chapter theme or start from scratch. There you can choose the font, font size, location and even add images. This way, you can make chapters look and feel like ‘your' book.

Since Atticus is the only one that has this advanced capability, it gets the point.

Point +1: Atticus

Minor Features

Minor features are those aspects that are important, but aren’t necessarily deal breakers for most people. However, I think you’ll find that even here, Atticus excels.

  1. Word count options: Both apps let you look at the word count, not just for a given chapter, but for the whole book as well. I’d say it’s a little more intuitive to find this information in Atticus, but for the sake of fairness, I’ll give this point to both. Point +1: Both.
  2. Chapter elements: When formatting a book, you need to know all the different parts of a book that you can add to your body, or front and back matter. Vellum and Atticus currently have the same number of chapter elements, so this one is a tie. Point +1: Both.
  3. Footnotes/endnotes: Vellum saves all footnotes as endnotes, and does not differentiate. Atticus doesn’t, giving it the edge in this situation. Point +1: Atticus
  4. Spellcheck: Both offer an in-app spellcheck, but Atticus is currently working to add ProWritingAid integration, which will eventually make it the clear winner in this category. For now, I’ll award the point to both. Point +1: Both.
  5. Large Print: While Vellum does let you create a larger font for your print books, there's actually more to large print (to be compliant with all the organizational guidelines) that Vellum does not do. Atticus, on the other hand, does it all. Point +1: Atticus
  6. Future plans: It might be a bit arbitrary to include this here, but I think it’s important to consider what the plans for a piece of software might be when determining its superiority. I’ll get into a breakdown of these plans below, but for now it’s clear that Atticus has more in the future (see its roadmap here) than Vellum does. If Vellum does have any development plans, this is not clear. Point +1: Atticus

If you’re keeping track that means that Atticus leads in the minor features at 6 to 4. Totaled all together with the major features, that’s an updated score of 14 to 7 in Atticus’ favor.

But that’s just the features that Atticus already has. What about the features that it doesn’t (yet) have. 

Upcoming Features

Lastly, it’s worth mentioning that Atticus is a relatively new software, and is growing and expanding every day. As such, there are a TON of new features that are on their way. Plus, as the creator Dave Chesson likes to say, it's not about just making a book formatting software, but instead, a complete suite of all things authors need to plan, plot, write, collaborate and format books. Dave likes to describe what Atticus will be by saying:

If Scrivener, Google Docs and Vellum got together and had a baby, its name would be Atticus!

Dave Chesson

Vellum on the other hand, has changed little over the years, and while I certainly have no inside information on any upcoming features they plan to implement, I have no past evidence to suggest that any such improvements are likely to happen soon. 

That said, I’ve made sure to give Vellum a point when I list an upcoming feature that Atticus doesn’t have yet, but Vellum does. Just bear in mind that that’s going to change soon as Atticus expands.

A few of the upcoming features that I'm excited about include:

  • Find and Replace: This tool will let you find anything within a given chapter or inside your entire manuscript, and allow you to replace it with anything you want. It is coming to Atticus very soon. Vellum has this, so I’ll give this point to them. Point +1: Vellum.
  • Volume and Parts: Volume, parts, and scenes are important because they allow you to group sections of a manuscript together into distinct parts, but also to create box sets. As of this writing, this feature is nearly done for Atticus. Vellum does have this feature (though they do not include scenes, which Atticus will have), so for now I give the point to them. Point +1: Vellum.
  • Reusable Elements: This is a feature that will allow you to have reusable elements (such as a universal Also By page) that can then be used across multiple books. Once Atticus has this, it will then update across all books if you make a change.
  • Dark Mode: This would allow the night owls among is to have a mode that puts less strain on the eyes in a dark environment.
  • Goal Setting/Tracking Goals: Atticus is meant to be an all-in-one tool. Part of what it needs to do is to have goal setting and tracking tools, where you could input writing goals, track word counts, see your progress, and more.
  • Organizational/Plotting Tools: A story involves much more than just the written text. There’s a lot of preparation that goes into it such as characterization, outlining, worldbuilding, etc. These features will eventually be integrated into Atticus, and are not currently part of Vellum.
  • ProWritingAid Integration: So far, all Atticus and Vellum have are standard spell checks, and lack in advanced tools for this. Atticus plans to eventually partner with ProWritingAid (our longtime recommendation as the best editing tool), would set it above Vellum in this area as well.
  • Collaboration Tools: Eventually, Atticus will see tools to allow co-authors to work together on their manuscripts, without the need to constantly be passing files back and forth, or worry about which version is which.
  • Version Control: This would allow you to save multiple versions of the same manuscript without having to create separate files for all of them, making it even easier to keep your work safe.

In short, there is a lot of great features coming down the pipeline. And most of them Vellum doesn’t even come close to having. 

Atticus vs. Vellum: The Bottom Line

If you tally all the points above, you get a score of:

Atticus: 14

Vellum: 9

That makes Atticus the clear winner of the two, even if your only goal is to format books (Atticus will do a lot more than just formatting). And that's not to mention all of the upcoming features that are sure to shift the tide even more in Atticus' favor.

All in all, Atticus will give you the same features that Vellum provides, without skimping on quality, and it also has a number of features that Vellum sorely lacks (such as the theme builder). And it does all that for almost half the price of Vellum.
