What is Prototyper?


Prototyping and simulation tool that allows to capture and manage Requirements



Prototyper lets you build prototypes and simulations for web applications, cellphones, desktop software and ERP. Validating Functionalities about high fidelity prototypes means benefits such as cost reductions, changes happened during the development stages and the rise of the quality of the delivered applications.


Rich interactions

Prototyper allows you to create prototypes with rich interactions that simulate the behaviour of the user interaction with the application: Ajax-js behaviours, mobile interfaces or even desktop applications.



Data Simulation

Prototyper lets you simulate the forms and Datagrids true behaviour, without having data base knowledge. Real data can be loaded if the user wants the highest level of prototype fidelity.

Business Rules and Validation

The analysts and the designers may define business rules and validation in the interactions, the forms and the datagrids. Prototyper provides a virtual environment where the rules can be created by dragging-and-dropping.


Reusability: Masters, Templates and Components Libraries

Prototyper lets you reuse all the work already done for a project trough the customized component library creation. In addition, global changes in a component can be created during the Masters. The template lets you share content between interfaces and create style guides.


IRQA Prototyper


Create Prototypes in HTML and Document Generation

Prototyper lets you export prototypes to HTML-CSS-javascript and generate documents of the customized specifications.

It is a Prototyping and simulation tool that allows to capture and manage feedback from users and customers and perform user tests. Users will be able to:
Publish prototypes
Review and validate prototypes with the user’s web browsers
Conversational annotations over the elements of a prototype
User testing tools integration


Communicate ideas visually between domain experts and IT
Avoid requirements inflation which threatens estimates and timelines by involving customers and developers
Validate functional requirements through simulations
Reduce poor productivity due to delays in early project stages which can never be regained
Stop specification breakdown caused by incomplete requirements
Speed up project development: save time in the development process, simplifying the revision process and integrating final users in the process, thus ensuring the right use of the final product. Prevent changes in critical stages of projects
Reduce costs, avoiding rework: save money during the elaboration of the app up to 30%
Avoid risks and failures in your projects: early detection of issues and limitations thus easing changes in requirements and specifications
Better definition of user requirements. This tools offer the possibility to carry out user tests using the interactive prototype as if it was the real thing
Better communication between all developers and non-IT literate Business professionals all along the production process so that everybody can work in-sync
Remote user tests to insure the best user experience before even developing the final app
Visualization of changes and keep track of the design evolution all along the production process
Match business rules with user experience


Who needs it?


Analysts and Project Managers
- Simulate functional scenarios without coding
- Simulate business data without database knowledge
- Generate documentation for proposals, specification documents, and more from a complete prototype

User Experience and Web Designers

- Design and simulate the information architecture
- Simulate user experience through real-time interaction

Requirements Simulation – The integration with Visure

The integration between Justinmind Prototyper and Visure allows gathering an early feedback from the users and perform a requirements validation straight from the beginning, shortening lifecycle and avoiding unnecessary costs.

Prototypes are developed and simulated in Justinmind Prototyper according to the requirements defined in Visure, and feedback is gathered among the users making use of online publications of the prototypes.

Comments to the online version of the prototypes can then be promoted to requirements and brought back to Visure to be considered as change requests to the specification.

The integration of the prototypes with User Testing Tool and analytics allows performing at a very early stage usability tests to help define this non functional aspect of the developments.

This bidirectional integration allows creating a seamless flow of information between Business Analysts and User Experience specialists, and streamline the communication with end users.


User note


Online collaborative platform for publishing and reviewing website wireframes and to carry out usability testing with all the main tools.

Publish Wireframes
Publish your website wireframe online and simulate it anywhere. Anyone you invite can interact with your prototype using the web browser.

Collaborative annotations
Users and stakeholders will be able to comment every wireframe element using web annotations. Just like threads in a forum, your users can comment straight on your wireframe elements or respond to previous annotations. This is great to keep track of the evolution of your wireframe.

Managing Annotations
Prototyper lets you import all the threads and discussions your users made in User note to see what components need to be edited. You can improve your website prototype thanks to key users testing and comments. This is great to design wireframe or prototype.
