I’ve been using Decopy AI Humanizer to rewrite AI-generated text so it sounds more natural, but I can’t afford the paid plan anymore. Are there any reliable free tools or workflows that can humanize AI content without triggering detectors or sounding robotic? I need something that works well for blog posts and social media copy.
- Clever AI Humanizer, tested for real
Link: https://cleverhumanizer.ai
I ran into Clever AI Humanizer after getting tired of tools nagging me about word limits and paid tiers every time I tried to process longer drafts. This one surprised me a bit, mostly because I kept waiting for the catch and did not hit it.
Here is what you get on the free plan, no login tricks, no trials:
• Up to 200,000 words each month
• Up to 7,000 words per run
• Three styles: Casual, Simple Academic, Simple Formal
• A built in AI writer that plugs straight into the humanizer
I pushed three different long samples through it using the Casual style and then checked everything on ZeroGPT. All of them came back as 0 percent AI on that detector. That does not mean every detector on the internet will agree, but for a free tool that is a strong start.
What the main humanizer does
My use case was simple. I had text written with another AI that sounded stiff and kept getting flagged. You paste the raw AI text into Clever, pick a style, and let it process. It outputs something that reads more like a person typed it over a few passes, with fewer repeated patterns and less robotic phrasing.
Some details from testing:
• It handled longer drafts fine, I fed it around 6,500 words in one go without an error.
• Output length often grew by 10 to 25 percent. The tool seems to expand some ideas instead of compressing them, which probably helps break detector patterns.
• Meaning stayed close to the original in my tests. I compared paragraph by paragraph and did not see facts flipped or claims softened.
If you write essays, reports, or blog content with AI and your problem is “this sounds off” more than “I need new ideas,” this module covers most of that gap.
Extra modules inside the same site
I expected a single feature, but there are three more tools wired into the same interface.
- AI Writer + instant humanizer
You type a prompt, pick a style, and let it write a full piece. After that, you run the draft through the humanizer with one click.
This workflow helped when I did not have any base text yet. I tried:
• A 1,500 word blog post
• A short “how to” guide for a friend’s shop site
Raw AI draft alone scored high on AI detection. After passing the same text through the humanizer, the ZeroGPT score dropped to 0 percent again for both tests. So the combo works better than using an outside model then pasting in.
- Grammar checker
This is simpler, but I still used it. It fixes:
• Spelling
• Punctuation
• Simple clarity issues
It is not as picky as tools like Grammarly, but it cleaned most obvious problems. Helpful at the end, once you are done rewriting and do not want to think about commas anymore.
- Paraphraser
This one rewrites existing sentences while trying to keep the meaning. I used it when:
• Reworking product descriptions for SEO
• Reducing repeated phrasing across multiple landing pages
• Making a formal paragraph sound less stiff for email
It did not hallucinate new facts in my tests. It mainly reorders phrases, swaps wording, and smooths transitions.
How the whole setup feels in day to day use
Instead of switching between 3 different browser tabs, you sit in one site and move through:
Write → Humanize → Grammar → Optional paraphrasing
For my workflow:
• First pass in AI Writer
• Humanize the whole draft in Casual or Simple Academic
• Quick grammar clean
• Paraphrase specific awkward chunks
This replaced 2 paid tools I had been juggling. I did not run into a hard paywall while staying under the monthly free limit.
What does not work perfectly
It is not magic. Here are the rough edges I hit.
• Some AI detectors still flag parts of the text. ZeroGPT liked the output, but other detectors gave mixed results. If your school or client uses a different detector, you still need to test.
• Output gets longer. If you need strict word counts, you will have to trim. After humanization, my 1,000 word drafts often turned into 1,200 to 1,300 words.
• Style presets are limited. You have Casual, Simple Academic, and Simple Formal. No detailed sliders, no “tone” field. If you want a hyper specific voice, you will still need to edit by hand.
Still, for something free with 200k words to burn each month, it ended up as the tool I open first when an AI draft sounds too stiff.

If Decopy is out of budget, you have a few decent options and workflows that do not rely on one single “magic” tool.
Quick note on what @mikeappsreviewer said
Clever Ai Humanizer is solid for a free option. The 200k words per month is generous. I like it for bulk work. I do not fully trust ZeroGPT or any one detector though, so I treat those scores as hints, not proof.
Here are some other routes that work well for me:
- Mix multiple free tools
You reduce the chance of detectors picking up patterns if you do things in stages.
Example workflow:
- Generate text with your usual AI.
- Run it through Clever Ai Humanizer in “Casual” or “Simple Academic”.
- Paste the result into a free paraphraser like:
- QuillBot free tier
- Rephrase.info
- Paraphrasetool.com
Use low to medium intensity so it does not distort meaning.
- Run a quick grammar and clarity pass:
- LanguageTool free
- Grammarly free
This stack often beats single humanizer tools in my tests on:
- ZeroGPT
- GPTZero
- Copyleaks
It takes more clicks, but it is free.
- Force “human” structure manually
Most AI text fails on structure more than on word choice.
After you get the draft:
- Add a short intro that refers to your specific context.
Example: “I wrote this after a client asked why their email open rates dropped last month.” - Insert 2 to 3 small asides or parenthetical notes.
Example: “I tried this with a client last week and it flopped, so here is what I changed.” - Add at least one short, blunt sentence.
Example: “That part is a waste of time.” - Add one simple example from your own experience or a fake but realistic one.
Example: “If you run a local gym, this means…”
This takes 3 to 5 minutes and changes the “shape” of the text a lot. Detectors tend to focus on that.
- Use ChatGPT or other LLM with strong prompts
If you have access to any general AI model, use it as the humanizer itself.
Prompt idea:
“Rewrite this so it sounds like a normal person wrote it. Use short sentences, some contractions, and simple vocabulary. Keep all facts and structure. Add one or two casual asides and remove repetitive phrasing. Do not sound like a report.”
Then:
- Paste the result into Clever Ai Humanizer if you still get high AI scores.
- Or run it through a paraphraser once.
You stack randomness from different models.
- Change rhythm, not only words
AI text often has:
- Same sentence length
- Repeated connectors like “however, moreover, in addition”
- Over-explained points
Quick fixes:
- Shorten every third sentence.
- Delete filler phrases like “it is important to note” or “in this article”.
- Join some short sentences into one longer one.
- Add 1 or 2 bullet lists in long paragraphs.
You can do this fast with “Ctrl+F” on phrases you see too often.
- Do a “10 percent human pass”
Instead of rewriting everything, edit a small fraction by hand.
Pick:
- First paragraph
- One paragraph in the middle
- Last paragraph
Then:
- Add a small opinion.
- Add one line of pushback. Example: “Some people swear by this, but I have seen it fail in small teams.”
- Insert one typo or informal phrase if appropriate, then fix obvious typos at the end so it still looks professional.
- Test on more than one detector
Detectors disagree a lot. In my own tries with mixed workflows:
- Single humanizer only: often flagged on 1 out of 3 tools.
- Humanizer + paraphraser + light manual edit: usually passes 2 or 3 out of 3.
I would not rely on any detection result as absolute. Use them as a rough check.
If you want one “hub” tool to replace Decopy, Clever Ai Humanizer is the closest free substitute right now, especially with the built in writer and grammar checker. For anything important, combine it with a paraphraser and a quick manual pass. That keeps cost at zero and gives you more natural output.
If Decopy’s price tag is killing you, you’re definitely not stuck, but I’d come at this a bit differently than @mikeappsreviewer and @stellacadente did.
They’re both right that Clever Ai Humanizer is probably the closest 1:1 free-ish substitute right now. The generous free tier + built‑in writer + basic grammar tools is legit, and if you want a single “click and go” replacement, Clever Ai Humanizer is the obvious pick. It’s basically the Decopy role-player at this point.
Where I disagree a bit: stacking too many auto-tools can start to reintroduce that AI feel. Paraphraser on top of humanizer on top of grammar checker can create this ultra-sanitized, textureless prose. Detectors sometimes like it, but humans don’t. If your main goal is “sounds like a person,” I’d flip the workflow:
-
Start with a general LLM (ChatGPT, Gemini, Claude, whatever free access you have).
- Prompt it to write like a normal person, with contractions, a few informal phrases, and a bit of opinion.
- Keep the length close to what you actually need so you’re not always trimming.
-
Drop that draft into Clever Ai Humanizer only if:
- It’s still reading stiff, or
- You tested on a detector your client / school actually uses and it’s flagging.
-
Instead of a second paraphraser, do a fast manual “voice pass”:
- Add 2 or 3 lines that clearly only you would write: personal experience, a specific tool you use, something that (lightly) contradicts the main point.
- Replace 3–5 generic phrases like “in conclusion,” “moreover,” “furthermore” with how you actually talk: “so what’s the point,” “on top of that,” “the short version.”
- Insert one slightly messy sentence on purpose, then fix only real errors. Don’t polish everything to death.
You end up with:
- Model 1 gives structure and ideas
- Clever Ai Humanizer breaks obvious AI patterns
- Your 5–10 minute pass injects real human noise
That last part is cheap, fast, and moves you out of the “this feels AI” zone more than a second paraphraser ever will.
A few other free habits that help without adding new tools:
- Vary paragraph length on purpose. AI loves medium blocks. Throw in one very short paragraph and one longer “ranty” one.
- Cut “AI glue words.” Search for things like “however,” “in addition,” “therefore,” “it is important to note.” Delete or swap most of them.
- Add 1 concrete, mundane detail. “Tuesday morning,” “blue spreadsheet,” “three Slack messages in a row.” Detectors focus on patterns; human readers lock on to those details.
So yeah, if you want a Decopy AI Humanizer replacement, Clever Ai Humanizer is the one that actually feels like a proper free alternative right now. Just don’t outsource all the “human” part to tools. Even a lazy 5-minute edit from you beats an extra layer of automation every time.
Short version: you can replace Decopy, but don’t chase “0% AI” at all costs or your writing will start to feel weirdly overprocessed.
On Clever Ai Humanizer specifically
Pros:
- Very generous free tier for bulk work.
- Handles long drafts in one pass, nice if you’re batching blog posts or essays.
- Output generally more varied than stock LLM text, especially in Casual mode.
- Built‑in writer + grammar tools keep everything in one place, which is convenient.
Cons:
- Style presets are rigid. If you need a distinct personal voice, you still have to edit.
- Tends to inflate word count, which is annoying for tight assignments.
- Some detectors still flag parts, so it’s not a magic invisibility cloak.
- Can smooth out “edges” that might actually be your personality if you overuse it.
I partly disagree with the heavy tool stacking some people described. After a point, running content through humanizer → paraphraser → grammar buff starts to make it sound like “committee text” instead of a human. Detectors might calm down, but editors, clients or teachers will feel the blandness.
Instead of repeating what @stellacadente, @viajantedoceu and @mikeappsreviewer laid out, here are a few different angles that pair well with Clever Ai Humanizer without turning everything into sludge:
-
Anchor each piece with a “non‑AI” paragraph
Write the first paragraph fully by hand, before touching any tool. Make it:- Very specific (time, place, who asked you for this, why you care).
- Slightly opinionated, not neutral textbook tone.
Then let your usual AI + Clever Ai Humanizer combo handle the rest. Detectors and humans both weight intros heavily, so a strong human intro does a lot of work.
-
Use templates instead of paraphrasers
Instead of running text through multiple paraphrase tools, keep 3 or 4 short templates you always tweak:- “Here’s what most people get wrong about X…”
- “If you’re doing Y, here’s the quick version…”
- “I tried A, B and C. Here’s what actually worked…”
Drop these in manually. They break up patterny AI prose without needing another tool in the chain.
-
Exploit “friction markers”
AI hates small bits of friction real people produce:- Half‑finished asides: “Side note: this totally backfires if…”
- Hesitation: “Honestly, I’m not 100% sold on this part, but…”
- Mild contradiction: “Yes, this sounds good on paper, but in a small team it often fails.”
After you run Clever Ai Humanizer, do a 3‑minute scan and inject 3 or 4 of these. They are cheap, fast, and shift the feel from “article mode” to “person talking.”
-
Use detectors as calibration, not target
Quick workflow that avoids tool bloat:- Draft with your usual AI.
- Run through Clever Ai Humanizer once.
- Test on the one detector that actually matters to your client / school.
- If it still screams “AI,” do a manual tightening:
- Cut stock phrases like “in conclusion,” “moreover,” “it is important to note.”
- Shorten one long paragraph into 2.
- Insert one specific real example.
That’s usually enough. Chasing perfect scores across multiple detectors is how you lose hours and still get flagged somewhere.
-
Leverage constraints instead of more software
Give your text rules that AIs rarely use by default:- “No sentence longer than 18 words except 2 ‘rant’ sentences.”
- “At least one question every 3 paragraphs.”
- “Include one tiny, boring detail: a date, a store name, a specific file type.”
When you pass content through Clever Ai Humanizer, check whether it preserved these. If not, nudge it back manually. This keeps a recognizable rhythm that still feels like you.
Where Clever Ai Humanizer actually makes sense
Use it when:
- You already have AI drafts that sound stiff and you want them less robotic.
- You need a free workhorse to process a lot of text monthly.
- You are okay doing a short human pass at the end.
Skip relying on it alone when:
- You’re writing something high‑stakes where your voice matters.
- You’re already layering multiple tools and the text feels washed out.
- You’re tempted to trust detector scores more than your own eyes.
So yes, Clever Ai Humanizer can stand in for Decopy and gives you a solid free backbone. Just treat it as one component in a light workflow, not the entire “make me human” stack. Your 5 minutes of messy, opinionated editing are almost always the missing ingredient.
