Aify by Ali

Rewrite or generate text based on promps using OpenAI's API. Configure on settings page (make sure to save) and start to use when writing blog posts or your emails!

You must have API key for OpenAI (anyone can access GPT-3.5, subject to change). But then you can use any model you have access to including finetuned ones.

Aify comes with plenty of stock prompts, which you can add to, delete or customize as you need.
