I kept finishing a paragraph and second-guessing myself, is the tone right? Is the grammar off? Having to constantly open ChatGPT, paste my text, and wait for a response got old fast.
So I built a tool to fix that. Since I’m already subscribed to ChatGPT and Gemini, I made TypeCat to streamline the process, paste your text, pick a tone and language, done. This tool supports OpenAI API, Gemini API, and Grok API.
Plug in your own API key, and it stays in your browser.
Give it a try 👇

Also support Singlish leh. 🙂


Install once. Works in every app — iMessage, WhatsApp, email, notes, anywhere you type on iPhone.

Connect your own Claude, Gemini, Grok, or OpenAI account. You control the AI, the cost, and your data.

Tap Formal for emails. Casual for friends. Persuasive for pitches. Or go full Singlish leh.
