About the project

Promtify: Merge’s own AI template builder

We at Merge, after creating numerous MVPs for our partners and motivated by a desire to leverage our expertise in AI integration, we decided to build our own AI product — Promtify.

Unlike similar AI apps that were hard to use, we focused on making Promtify simple and good-looking. Our journey started with a basic version to test our idea, emphasizing the frontend and integrating the OpenAI API. Realizing that functionality alone wasn't enough, we added a thoughtful design, a subscription model, and a robust database. Our goal was to transform Promtify into a tool that's not just useful but also enjoyable to use.

Fast idea validation

Speed and efficiency were paramount in testing the Promtify concept. Recognizing the need for swift idea validation, we adopted an agile approach. By focusing only on essential features and the frontend, we ensured a lean and resource-efficient development process.

Leveraging our in-house expertise and a well-defined development strategy, we efficiently integrated the OpenAI API, allowing us to test the core idea without excessive resource allocation. This agile methodology not only reduced time-to-market but also optimized costs.

UX-focused design for AI products

In our quest for an outstanding user experience (UX) within Promtify, our AI design approach was straightforward. Tackling the challenge of creating a user-friendly template builder, we opted for the practical Slate.js library, ensuring a streamlined environment. This decision not only facilitated efficient template creation but also catered to our project's unique needs.

The journey didn't stop there; a steadfast commitment to user satisfaction led to ongoing refinements. User feedback prompted us to improve usability, resulting in a more polished version released two months later.
