AI humanizer for blog posts
How to take an AI-drafted blog post and make it read like a person with opinions wrote it, without losing the facts your readers came for.
Open the humanizer. It is free: try 400 words without an account, or sign in with Google for 6,000 words a day, up to 1,200 words per paste.
What makes an AI blog post sound like AI
- An opening about "today's fast-paced world" or "the ever-evolving landscape".
- Every section the same length, each ending with a one-line summary.
- Lists of three, everywhere, and transitions like "moreover" and "furthermore".
- No opinion, no first-hand detail, nothing a reader could not have guessed.
How to humanize a blog post with Penned
- Open the humanizer with the Blog post style.
- Paste the draft, up to 1,200 words at a time. Split longer posts at their headings.
- Penned rewrites each paragraph several times, scores every version with an AI detector and fact-checks the best one against your draft.
- Read it, then add what only you know: a result you measured, a mistake you made, a product you actually used.
What stays the same
- Headings and short lines.
- Numbers, prices, dates, product names and brand names.
- The order of your points.
How well it works on blog text
In our GPTZero tests in October 2026, an AI-written blog post scored 0% AI after two separate Penned runs. These are small tests; check your own result in the AI detector.
Questions
Does Google penalise AI-written blog posts?
Google's guidance is that it ranks helpful content however it was made, and acts against pages mass-produced mainly to rank (its scaled content abuse policy). Humanizing makes a draft read better; it does not turn a thin post into a useful one. Add your own experience, examples and data.
Will my headings and links change?
Headings and other short lines are passed through as they are. Penned rewrites paragraphs. Paste plain text; links and formatting need to be added back in your editor.
How long can a post be?
Up to 1,200 words per paste when signed in, 6,000 words a day free. A longer post goes in two or three parts, split at its headings.
