ChatKit

ChatKit.app is a refined interface for ChatGPT that lets you use your own OpenAI API key for full control and transparency over your usage. It goes beyond the standard ChatGPT experience with real-time features that make conversations more powerful and contextual — including the ability to use URLs as chat context, full-text search of your entire chat history, and voice input powered by the Whisper API. Additional features like prompt templates, chat bookmarks, text-to-speech, web search, and URL fetching make ChatKit a genuinely more capable and personalized way to interact with GPT models every day.
