How can I make AI-generated writing sound less formal and more like me?

The quickest way to make AI writing sound less formal is to paste your own casual writing sample into the prompt and tell the AI to match that tone, since most tools default to a neutral, slightly stiff voice unless you give them a specific style to copy. I've found this works better than just saying 'write casually' because the AI doesn't know what casual means to you. For some people, casual means using slang and sentence fragments. For others, it just means dropping the corporate jargon. The difference matters. A concrete example: instead of prompting with 'Write a blog post about meal prepping,' try 'Write a blog post about meal prepping in the same tone as this text: [paste a paragraph you've written].' The AI will pick up on your sentence length, your word choices, even how often you start sentences with 'And' or 'But.' Another trick that helps is asking the AI to rewrite something at a specific grade level. Saying 'rewrite this at an 8th-grade reading level' forces shorter sentences and simpler words. But here's the thing most guides miss — you should also check for words the AI overuses regardless of tone. Words like 'additionally,' 'moreover,' and 'crucial' are dead giveaways. If you spot those, just tell the AI 'remove all transitional adverbs' in a follow-up prompt. If you're tired of tweaking tone manually every time, tools like AI-Mind are built to avoid that formal, robotic voice from the start, so you spend less time editing.
