Frequently Asked Questions

All Chatbots are built with OpenAI's latest technology so that you can interact using both voice and text.

- AI Chatbots - React Native - Flutter - FlutterFlow - Native iOS (Swift, Objective-C) - Native Android (Kotlin, Java) - Web Development

We start with an initial call where we discuss your business, challenges, and goals. If we find alignment in our approach and needs, we move forward. If not, we’re still happy to provide guidance.

It helps to have a clear idea of your business, any existing development experience, your budget, and your timeline. We’ll also ask about your goals and the problems you’re trying to solve with your app.

We follow a structured process that starts with a Discovery Workshop to identify potential issues and refine your app concept. We provide weekly updates, rigorous testing, and clear communication to ensure your project stays on track and meets your expectations.

- Custom AI Training and Mobile App Development - Integration with ChatGPT and OpenAI - App Support and Maintenance - API integration - OpenAI Development - Data visualization and data analysis

Our process begins with a workshop to understand your needs, followed by scoping to outline the project, timeline and costs. We then proceed with development, conduct thorough testing, and finally, release the finished app.

The initial call is designed to uncover your requirements for the app and to find the best way for how to develop it. All of your questions will be answered and you will get a ballpark quote for how much the app will cost to develop.

We're able to develop two apps for the price of one by using Flutter or React Native frameworks, allowing us to develop a single codebase that runs on both Android and iOS platforms efficiently. This streamlines the development process, reduces costs, and ensures consistency across both platforms.

The main goal is always that you are a satisfied customer. That's why we agree on a project scope that declares exactly what the result of the app should be. If any small adjustment needs to be done within the project scope, this can be considered a revision if requested within 2 weeks of release.
