Compare two PDFs in real time
XOR is a viewer app (Mac/Windows) that compares two PDFs (before and after correction) in real time.
You won’t have to wait for the comparison results to appear. XOR shows you the results as soon as you start the comparison.
You can see the differences in two ways.
-
Transparent way (red and blue are differences) -
Flip way (the blinking part is the difference)
You can see the real-time comparison in action in the video “How to use XOR (Japanese)”.
Trial
XOR has a one month free trial period. You can download and try it from either store.
Usage
Check out this video on how to use XOR and how it works.
Purpose
In print production, editors and operators repeatedly revise and proofread their work to achieve completion.
XOR is ideal for the following verification tasks in proofreading.
- What has changed?
- Is that change the right fix?
- Do you have any missing corrections?
- Are there any unnecessary changes mixed in?
Comparing printouts of proofs and looking for changes can be a daunting task. It requires a high level of skill and concentration. And a lot of time.
But you can quickly identify all the changes in two PDFs by using XOR. That means you can understand the pages and areas of the page that haven’t been changed. You can save time on proofreading, by excluding them from the target of confirmation.
Subscription
XOR is offered on a subscription basis for 2,000 yen per month (*). Therefore, companies can review the number of subscriptions as the number of production staff increases or decreases, and there is no waste. Therefore, the company can optimize the number of contracts as the number of production staff increases or decreases to avoid waste.
* Prices outside the Japanese store are determined by the exchange rate.
No USB dongle required
XOR does not have a USB dongle to manage licenses.
You can use the same account (Apple ID or Microsoft account) with a single license at work, at home or on the road. This makes XOR ideal for remote work.
With XOR in place, you won’t have to go to the office when you have a holiday emergency. And you won’t have to cancel your trip.
Latency is a cost
Latency is a cost in your business.
For example, if you’re using some PDF comparison app that required USB dongle, you might have to wait your turn to use the app.
Or when you wait until the DTP is finished, then do the proofreading at night, it’s a double cost to the company by the waiting time and overtime. Moreover, you’ll come home late.
But with XOR, you can reduce those costs. That app can be deployed for the entire staff, run speedy, and can be used outside of the office.
Ease of use > Functions
Simple is best. The ease of use sometimes outweighs the full range of features!
With XOR, you don’t need to adjust comparison settings for each PDF feature you want to compare. Plus, you get an intuitive understanding of the comparison results. You don’t need to wade through difficult reports.
And you’ll get a lot of achievements by using the simple and light app rather than use a multifunctional app.
Never miss a difference
XOR finds all differences that recognizable by eyes between the two PDFs by visually comparing them.
In the type of PDF comparison app that analyzes and matches two PDFs, the comparison algorithm may miss the differences when the PDF contains unexpected changes.
