Humanize 360 vs Grammarly AI Humanizer: short passages or whole documents
Grammarly's AI Humanizer is free and lives beside the best-known grammar and clarity assistant there is, with a browser extension and its own AI detector. It is good at quick tone fixes on short passages. Humanize 360 is built for the other end of the scale: a 4,000-word report as a DOCX, a batch of client posts, an essay with citations that must not move. Both are worth having; they rarely compete for the same job.
Grammarly Premium is a paid subscription for the wider assistant, and the humanizer is free. Humanize 360 is free for 300 words a run and sells packs valid for twelve months and plans in local currencies beyond that. Our own grammar checker is also free, with a UK/US toggle, and explains every fix, though we would not claim it matches Grammarly's assistant.
Where Grammarly stays the better tool
Grammar, clarity and tone suggestions while you type. If most of your AI-assisted writing is an email, a comment or a paragraph that needs to sound a little less stiff, Grammarly's free humanizer inside the editor you already use is hard to beat for convenience. There is no reason to pay us for that.
Where a dedicated humanizer earns its place
- Whole documents: PDF, DOCX, TXT and MD in, PDF, DOCX or TXT out with headings, lists and paragraphs kept; batch runs on Standard and above.
- Control: eight modes, a Light, Balanced or Heavy strength, protected words, a custom style profile from 300 words of your own writing, and a Changes view.
- Academic mode that protects citations and numbers and removes contractions by default.
- A grammar guard that runs on every humanized output so the rewrite does not introduce errors.
What three writers would pay
A student humanizing one long essay a term buys a Starter pack from us once, from ₦1,500, and keeps the balance for a year, or uses Grammarly's free tool passage by passage. A freelancer producing weekly client documents fits our Standard plan, priced in naira, cedi, shilling, rand, pounds, euros or dollars. An agency gets seats, API and invoices on Pro. Grammarly Premium is a separate decision about the assistant, not the humanizer.
Privacy and a five-minute check
Humanize 360's engine is our own code with no third-party language model, so a client's document is never sent to another AI company; anonymous runs are discarded after the result is returned and uploaded files are deleted after seven days. Grammarly publishes its own privacy terms. To compare, humanize the same 300-word passage in both, then a full document in ours, and check each result in our free AI detector for the eleven-signal breakdown.
