Scored by a Toolio reviewer after real useOur verdict
Ally is a bare-bones rewriting plugin that runs on your own OpenAI API key rather than a bundled subscription. You choose from stock prompts, edit or delete them, and switch models including fine-tuned ones once you have access. Without an API key already in hand, or a tolerance for paying OpenAI directly per use, there's nothing to use here.
