Perfect for handling a specific document I needed to function a certain way in my company's registrant onboarding workflow. The ease of use and vast array of options at my disposal only extend the functionality for future needs when they arise. We will continue to use Ultradox and I look forward to the new and exciting things they add in the future. Keep up the great work.

Ultrabox did what I needed it to do, for the most part. It's a steep learning curve and it wasn't intuitive on where to go for help. It was overwhelming. It would be helpful if there were step-by-step videos for general use cases. If this exists please direct me to it because I couldn't figure it out. I don't have time to look through a forum or ask in a community. I'd recommend it to people who are more computer savvy. This is way out of a beginners league.

I have lost a lot time not to find this wonderfull application. Some years ago you need to study hard softwarecoding to make all possible what is now possible nearly without any knowledge. totally i agree that it is a simple method to get my work done and even with a lot of fun. i feel reminded back playing with lego to improve my construction ;) thanx to developer and greetings to HH

I've been investing in automation platforms for the last two years with active subscriptions to zapier, integromat, parabola, n8n (cloud & self hosted). Even moved to low code solutions. This is an area of exploding growth and for good reason. Along with ETL and the likes, automation platforms are receiving funding probably most frequently than any other category with investments ranking in the upper levels. I started exploring Ultradox only recently, initially intending to expand my familiarity rather than diving in (seemed I had enough by now). Yet, a couple of hours afterwards I found myself building a PDF product catalogue template to present to two B2B clients the next day. That easy! Although there is overlap with many platforms I already use, UD is unique in terms of workflow clarity. That is, it is structured in a way that after a few moments playing around with the UI, you come up with 3-5 use cases. From a the technical perspective, being part of the GSuite family it grants immediate access to the Google API universe with minimum effort when it comes to authentication.

Very helpful and innovative. I didn't even had a idea such a thing exists. It has made my work super easy. You can make all your docs, forms, sheets dynamic and generate new pdf or whatever you want it to be converted into. It's a versatile software with a ease of making your work simple

Ultradox was exactly what I was looking for. Tend to use the G Suite apps over Microsoft Office as I'm an Android/Mac user so they fit my workflow. I'd not found any limitations with them until I attempted to merge a Google Doc with info from a Google Sheet. It just wasn't possible until I came across Ultradox. I'm giving it 5 stars because it does exactly what it says it does and for me it was pretty easy to get going, but I could see a less tech savvy user giving it 4 stars as the setup wizard is a little overwhelming and I found myself having to restart it a couple of times to be clear it would do what I wanted. My use case was create Google Docs based off a doc template and a Google Sheet, but the wizard language is geared more to full mail merge with Gmail.

As a HS Journalism and English teacher, I have to manage a ton of Google docs and workflow, from student peer reviews to mail merges to the myriad of bureaucratic minutiae with parent forms and permissions. For those tasks that can’t be done with a Google Form, Ultradox is my go-tool for automation and integration. It has saved me hundreds of hours of cutting and pasting . Don’t be intimidated by the initial learning curve; once you’ve mastered the basics, Ultradox is flexible, useful and intuitive.

Ultradox is hands down one of the coolest apps available on the G Suite Marketplace. The amount of flexibility it offers, especially if you have a little bit of technical experience is amazing! The first time I discovered this app, I spent like 5 hours playing around with different techniques, methods and strategies to achieve certain business objectives. Additionally, it acts as an awesome bundle pack across all your G-suite tools (Docs, Sheets etc) which allows you to do stuff like design a responsive email template in Google Docs, get it converted into HTML. Read contact details from Google Sheets and, send using Gmail or a third party API. Javascript options are awesome too if you know what you're doing, or if you can hire somebody to build some cool integrations with your existing CRMs etc. I'd like to be clear, I'm not just writing this to score myself brownie points or some kind of license upgrade. I am genuinely impressed with the way this app was built, and the possibilities it offers for SMEs. (Not to mention a cost saving of not requiring a bunch of third party apps or Chrome plugins - as this can be a replacement). Keep up the good work guys! - Eric

Amazing! I feel like I have just scratched the surface of the power of this application. I am a lawyer and the potential for this application to allow for document assembly and communication management is immense. Some have said the learning curve is steep, but if you have any experience in creating simple program logic and you can sit down and map out your flows the documentation is so well done that you should be a pro in no time. I am so glad I found it!
