PromptKit

What it does

PromptKit is an iOS app that works as a personal AI prompt library, generator, and workspace. It includes 300+ curated prompt templates across 18 categories, lets you save prompts into collections with tags and notes, and can run prompts directly with models such as ChatGPT, DeepSeek, Gemini, Grok, Llama, and Phi. It requires iOS 17.0 or later and syncs your library across Apple devices via iCloud.

PromptKit is built for people who write and reuse AI prompts often. You can start from one of 300+ curated templates across 18 categories or generate a custom prompt, then save it into collections with tags and notes. The app can refine prompts with built-in AI and run them directly against ChatGPT, DeepSeek, Gemini, Grok, Llama, and Phi, so you can compare answers without switching apps. It also supports one-click copy and export for tools like Claude, Midjourney, and Perplexity. The app is free to download with core templates and prompt-building tools, while PromptKit Pro is an optional in-app subscription that unlocks all prompts, unlimited collections, direct AI models, and an ad-free experience. PromptKit is natively built for iPhone and iPad running iOS 17.0 or later, and it uses a local-first database so saved prompts and core templates work offline. The library can sync across Apple devices through iCloud. The site states that prompt content is not tracked on remote servers and remains on your device and in your private iCloud container. Some marketing figures, such as estimated productivity boosts and time saved, are described as illustrative workflow estimates rather than guarantees.
