ChatKit

ChatKit offers a polished, feature‑rich interface for interacting with ChatGPT and other large language models. Users can connect their own API keys or use credits, adjust model temperature, access prompt templates, save bookmarks, and leverage text‑to‑speech, voice input, and web search. It supports OpenAI, Gemini, Azure and custom models, requires no login, and is available via a one‑time payment with regular feature updates.
