Typeflash is an AI chat and writing tool that uses ChatGPT and GPT-4. It is an alternative to the official ChatGPT app and fixes a number of shortcomings that the official app has:

Prompt library to manage prompts Editable assistant character and parameters Access live information through Google integration Compose mode to quickly draft long-form content Does not ask you to login again and again Keeps your data completely private (in the official app, your chat history is used to train future AIs) Faster responses than the free ChatGPT app, even when demand is high (equal to but cheaper than ChatGPT Plus)

Premium features such as web search are accessible with a single-payment, lifelong license.
