ProseKey AI

Overview

ProseKey AI is an iOS third-party keyboard designed to help users improve their writing on the go. Whether you need to proofread a sentence, rewrite text for clarity, generate summaries, or even convert text into a table, this keyboard provides quick AI-assisted features at your fingertips.

It supports Custom Instructions that you can define in the app and use in the keyboard. You can choose from multiple writing options, and the tool will either correct, refine, or transform your text using various AI models from providers including Gemini, Mistral, and OpenAI API.

The Windows/Linux versions are developed by Jesai Tarun (@theJayTea). The macOS version is developed by me.

This project wouldn't be possible without the original WritingTools Project by Jesai Tarun (@theJayTea).

Suggestions and ideas of @Joaov41 made this project much better and more functional. Specifically they helped me with adding automatic text detection (under 200 characters) to the app.
