What is StealthWriter AI?
StealthWriter AI is a tool made to rewrite text so it sounds more human. It's often used by students who are trying to become better writers and make their writing sound less robotic.
It works by changing sentence structures, swapping out phrases, and adjusting tone. The main goal is to make sure the content (like in an essay) looks like it was written by a person, not a bot.
However, it's one of many tools in a growing space of AI rewriters, and there are many better alternatives available.
Is StealthWriter AI Free?
StealthWriter AI offers a free plan that includes up to 300 words per request and a daily limit of 5,000 words. If you need more words, you have to upgrade or find a different tool.
To unlock full features or higher word counts, you usually need to upgrade to a paid plan. This pushes many students to look for other free options that don’t have usage caps.
