The Free Grammarly Alternative for AI Detection & Humanizing
Grammarly polishes grammar and tone across your whole workflow. humantext.pro does one job well: check if your writing reads as AI-generated, then rewrite robotic AI text so it reads naturally, free and with no signup.
Humanize your text freePick Grammarly if you want an all-in-one writing assistant that handles grammar, spelling, clarity, and tone across email, docs, and the browser. Pick humantext.pro if your main need is to check whether text reads as AI-generated and to naturalize robotic AI drafts, free and without an account. Grammarly now bundles its own AI checker and humanizer, but they are one feature inside a broad suite. Many people keep both: Grammarly for everyday writing, humantext.pro as a focused detect-and-humanize step.
Grammarly is one of the most recognized names in writing software, and for good reason. It is a full writing assistant that catches grammar and spelling mistakes, flags unclear sentences, suggests tone adjustments, and rewrites full sentences or paragraphs, all in real time across your browser, desktop apps, and documents. Grammarly now also includes its own AI checker (which estimates how much of a text may be AI-generated) and an AI humanizer that refines phrasing for clarity. If you want a single tool watching over everything you type, Grammarly is a strong default.
humantext.pro is deliberately narrower. It focuses on two closely related jobs: telling you whether your text reads as AI-generated, and rewriting robotic, machine-sounding AI drafts so they read more naturally while preserving your meaning. There is no account required for the free tier, you can start with up to 500 words per use, and it works across 27 languages. It is not a full grammar suite, and it is not meant to replace Grammarly for day-to-day editing. It is the tool you reach for when you specifically want to verify how your writing reads and smooth out AI-sounding text.
humantext.pro vs Grammarly

How the two compare
The two tools are built for different jobs, so comparing them head to head misses the point. Grammarly is a general writing assistant: its value is catching errors and tightening clarity and tone across everything you write, all day. humantext.pro is a focused readability tool: it exists to tell you whether a piece of writing reads as AI-generated and to rework robotic AI phrasing into something that reads more like a person wrote it. One is about correctness and polish; the other is about naturalness and verification. That is why the honest answer for many writers is not either-or but both, using each for what it does best.
Honest pros and cons
Where humantext.pro is strong
- Free AI detection and humanizing in one place, so you do not have to juggle two separate tools
- No signup for the free tier, paste text and get results instantly
- 500 words free per use, so you can try it before committing to anything
- Works across 27 languages when naturalizing AI-sounding drafts
Where Grammarly shines
- Best-in-class grammar, spelling, and clarity checking across apps, documents, and the browser
- Real-time suggestions plus tone and full-sentence rewrites that improve everyday writing
- A mature, widely trusted suite with deep integrations, its own AI checker, and Authorship tracking
Grammarly limitations
- —The free plan requires an account, and the strongest rewrite and tone features sit behind paid Pro (around $12 to $30 per month, as of 2026)
- —It is a broad writing suite, so detecting and naturalizing AI text is one feature rather than the focus
- —Grammarly positions its humanizer around clarity and natural tone rather than deep restructuring, so it may not rework heavily robotic AI drafts as much as a dedicated tool
Who should use which
Choose humantext.pro: You mainly need to check whether text reads as AI-generated and to rewrite robotic AI drafts into natural-sounding prose, for free and without creating an account.
Choose Grammarly: You want a full-time writing assistant that fixes grammar, spelling, clarity, and tone across everything you write, every day.
Our honest edge
The honest difference is scope. Grammarly is a broad, polished writing suite you pay for once you want its best features; humantext.pro is a single-purpose tool that pairs a free AI detector with a free humanizer in one screen. There is no signup, you get up to 500 words per use to start, and it works across 27 languages. We are not trying to replace Grammarly's grammar and clarity engine. We are the focused step you use when you want to see how your writing reads and make robotic AI text sound more natural.
Humanize your text freeGrammarly Alternative — FAQ
Is there a free Grammarly alternative?
Yes. humantext.pro is free to start, with no account required for the free tier and up to 500 words per use. It focuses on AI detection and humanizing rather than full grammar checking, so it is a good free option when your main need is to see whether text reads as AI-generated and to naturalize robotic AI drafts. Grammarly also has a forever-free plan, though it requires signup and centers on grammar and spelling.
Does Grammarly detect AI?
Yes. Grammarly now includes an AI checker that estimates how much of a text may be AI-generated, shown as a percentage, and a separate Authorship feature that tracks how writing was produced inside its editor. It is one feature within Grammarly's broader writing suite. humantext.pro offers a dedicated free AI detector focused specifically on whether your writing reads as AI-generated.
Can I humanize AI text for free?
Yes. humantext.pro lets you humanize AI text for free, up to 500 words per use with no signup. It rewrites robotic, machine-sounding phrasing so your text reads more naturally while preserving your original meaning. The goal is quality and readability, so you can review how your writing sounds and improve it.
Do I need both Grammarly and humantext.pro?
Many people use both. Grammarly is the everyday assistant for grammar, spelling, clarity, and tone across your apps, while humantext.pro is the focused step for checking whether text reads as AI-generated and naturalizing robotic AI drafts. They serve different jobs, so keeping both is a reasonable setup rather than a duplicate.
Is humantext.pro a full grammar checker like Grammarly?
No, and we are upfront about that. humantext.pro does not aim to replace Grammarly's grammar and spelling engine or its real-time suggestions across apps. It is a narrow tool for AI detection and for rewriting AI-sounding text to read more naturally. If you need comprehensive grammar and style coverage across everything you write, Grammarly is the better fit for that part.
