What it does
Rewrites AI-generated or AI-assisted text so it reads like it came from a person: varied sentence length, specific details instead of generic claims, and a tone you'd actually use out loud.
Who it's for
Job seekers polishing a cover letter or LinkedIn summary that started with AI help, and anyone sending outreach messages who wants the draft to sound like them, not like a template.
Before and after
A fictional example. Same information, rewritten for voice and specificity.
I am writing to express my interest in the Marketing Coordinator position. I possess a diverse skill set that aligns well with the requirements outlined in the job description. Furthermore, I am confident that my background in content strategy and my proven ability to collaborate cross-functionally would enable me to make a significant contribution to your esteemed organization.
I want to apply for the Marketing Coordinator role. I've spent the last two years building content strategy at a 12-person startup, which meant I was also the person pulling in design and sales whenever a campaign needed both. That mix, planning content and getting other teams to actually ship it, is what I'd bring to your team.
What this tool doesn't promise
This is a rewriting tool, not a detection-evasion tool. It won't guarantee a specific score on any AI detector, and detector accuracy changes constantly regardless of what wrote the text. What it does reliably is make stiff, repetitive AI phrasing sound more like something a specific person would actually say.
Common questions
Does this guarantee my text will beat AI detectors?
No. No tool can honestly promise that, and we won’t pretend otherwise. What the humanizer does is rewrite stiff, generic-sounding AI output into text with more natural rhythm, specificity, and voice. Detector scores vary by tool and change over time; readability and authenticity for a human reader are what we optimize for.
What kind of text should I paste in?
Anything that reads like a first draft from an AI assistant: a cover letter paragraph, a LinkedIn summary, an email, a short bio. The tool works best on text that already says the right things but sounds robotic, repetitive, or overly formal.
Is the humanizer free to use?
You can try it after creating a free SleevIx account. The free tier includes a limited number of humanize runs per month; higher volume is available on paid plans. See the pricing page for current limits.
