Building PromptKit: The AI Productivity App

PromptKit App Main Screen

Project Overview

PromptKit is a productivity toolkit for anyone working with AI daily. It provides a powerful, organized library of high-quality prompts, tools for creating and enhancing AI instructions, and seamless workflows for using and sharing prompts with any model—including ChatGPT, Midjourney, Claude, Gemini, and Copilot.

Project Duration

June 2024 – Present

The Product

PromptKit tackles the new productivity bottleneck: managing and reusing AI prompts efficiently. It’s built for creators, marketers, developers, teams, and anyone looking to maximize the value of AI models. Key features include:

  • Curated Prompt Library: Inspiration and ready-made templates for all top AI models.
  • Prompt Creation & Customization: Easily build and refine instructions, save notes, and update them using built-in AI tools.
  • Cross-Model Compatibility: Prompts can be used, tested, and compared across models—find what works best!
  • Organization: Categorize, tag, favorite, and manage your personal and team prompt library.
  • Instant Copy/Share: Copy prompts in a tap or share with a team or community.
  • Enhance Prompts: Use built-in AI to rewrite, expand, or improve existing prompts.

PromptKit is available on the App Store.

The Problem

AI is powerful, but managing effective prompts is overwhelming:

  • Users waste time searching for the right prompt, rewriting or remembering instructions.
  • There isn’t a great way to save, organize, and reuse or share prompts across models.
  • Teams need structure and inspiration to supercharge their AI workflows.

The Opportunity

  • AI is mainstream, but prompt management is fragmented and ad hoc.
  • Open models (ChatGPT, Claude, Gemini, etc.) rapidly evolve, making cross-comparison critical.
  • Professionals and teams are ready to pay for tools that help maximize their AI investments.

The Goal

Build the most useful, fast, and user-friendly prompt workflow toolkit for individuals and teams working with AI.

  • Help users organize, reuse, and enhance their best prompts.
  • Make creativity and experimentation with AI fast and rewarding.
  • Provide a bridge across popular AI models—making it easy to compare and improve results.

My Role

Solo designer and developer (iOS, SwiftUI); UX/UI, product architecture, development, App Store launch, support, and ongoing marketing.

Responsibilities

  • Investigated pain points and workflows of power users, AI professionals, content creators, and developers.
  • Designed robust, flexible UI: prompt cards, categories, search, favorites, easy sharing.
  • Integrated AI “enhance” features—refine and intelligently rewrite prompts.
  • Built for privacy and speed: everything is local (with iCloud sync) and no user prompts are shared.
  • Managed marketing, App Store assets, user support, and fast iteration based on feedback.

The Result

  • Personal Library: Store, tag, and organize an unlimited array of prompts with favorites, keywords, and notes.
  • Rapid Productivity: Turn AI experimentation into a repeatable, organized workflow.
  • Prompt Enhance: Instantly clean up, expand, or optimize your existing prompts with built-in AI helpers.
  • Cross-Model Ready: Compare how prompts perform with different engines (ChatGPT, Claude, Gemini, etc.).
  • Instant Share: Empower teamwork or the AI enthusiast community.
  • Beautiful iOS Experience: Intuitive, privacy-focused, and visually polished.

Impact

  • Empowering marketers, content creators, students, developers, teams, and AI enthusiasts worldwide to get the best out of AI—faster.
  • Saving users hours per week by making prompt management and retrieval painless.
  • Early users praise its robust organization and the “Enhance” AI feature.

Reviews

“This app is very useful for engineering custom AI prompts and for using their created prompts to do research and create post, study material (lessons), business ideas, and a host of other uses for AI, social media, business, work platforms. I highly recommend this app for AI novices and those needing to learn how to create and generate prompts.”

What I Learned

  • Efficient prompt management is still a weak point in most AI workflows.
  • AI-assist features directly in productivity apps dramatically boost user value.
  • iOS users demand privacy, speed, and offline functionality—even for AI tools.
  • Successful apps require continuous updates: responsiveness to user input is critical for growth and word of mouth.

Takeaways

  • Embrace rapid iteration—user needs in the AI space change quickly.
  • “Enhance” and AI-based meta-tools are true differentiators for power users and teams.
  • Focused organization (tags, categories, favorites) transforms how users experience their AI “stack.”
  • Simplicity and performance on mobile are key drivers of adoption.
