GPTHuman
Best for Writers and small publishers humanizing their own AI-assisted drafts at budget — detector-rewriter loop, 25,000 words/mo at $8.25/mo annual, 50+ languages and developer API included.
Teams that screen content before publication need Originality.AI: detection plus plagiarism in one combined scan, Deep Scan naming the exact sentences to fix, and a vendor that replies to 100% of negative reviews — the tool you pay when a decision gets made about someone’s draft. Writers fixing their own flagged drafts on a budget need GPTHuman: detector and rewriter in one loop from $8.25/mo annual, with Shield Guard and watermark removal from the first paid tier — the tool you pay when the text is yours and the scanner is someone else’s. GPTHuman’s documented trade: an "Unlimited" plan with a vendor-controlled asterisk and a 16-review Trustpilot record including a failed-pass and a refused refund. Originality’s: monthly credit expiry, full-credit re-scans, and an October 2026 model update that drew accuracy complaints.

Side-by-side deep dive
What it does best
- Low paid entry for the category: $8.25/mo billed annually ($99/year) for 25,000 words/month, with Shield Guard and watermark removal included from the first paid tier.
- The free trial needs no credit card and still includes watermark removal, 50+ languages, the Human Content Generator, and limited AI-detector use — enough to judge output quality before paying.
- Detector and rewriter live in one loop: run the built-in AI detector and re-humanize instantly until the text reads 100% human, instead of juggling separate tools.
- Developer API with claimed 99.9% uptime, sub-second responses, and a no-content-storage policy — production plumbing unusual at this price point.
The catch
- The $26/mo 'Unlimited' plan carries its own footnote — '*Unlimited subject to abuse guardrails' — an undisclosed, vendor-controlled cap on the headline promise.
- Per-output ceilings of 300/1,000/1,500/2,500 words by tier force long documents through multiple runs, burning the monthly quota faster.
- Young product with a thin review base: Trustpilot 3.9/5 from just 16 reviews (profile claimed Nov 2025, no replies to negative reviews) and a G2 profile with zero reviews at capture.
What it does best
- Full originality stack — AI detection, plagiarism, readability, grammar, and fact/hallucination checks — funded from one credit balance
- Deep Scan explains which sentences look AI-generated and suggests ethical edits
- Writing Replay in the Chrome extension evidences authorship while scanning in Google Docs
- Replies to 100% of negative Trustpilot reviews, typically within 24 hours
The catch
- Subscription credits expire monthly — unused Pro credits vanish at renewal
- Re-scans charge full credits even after minor edits
- October 2026 5.0 model update drew accuracy complaints and removed legacy models without refunds

Final verdict
Our pick: GPTHuman
Teams that screen content before publication need Originality.AI: detection plus plagiarism in one combined scan, Deep Scan naming the exact sentences to fix, and a vendor that replies to 100% of negative reviews — the tool you pay when a decision gets made about someone’s draft. Writers fixing their own flagged drafts on a budget need GPTHuman: detector and rewriter in one loop from $8.25/mo annual, with Shield Guard and watermark removal from the first paid tier — the tool you pay when the text is yours and the scanner is someone else’s.

Full comparison
Method
Researched from both vendors’ pricing pages, docs, and review profiles, verified 2026-10-26. Both tools publish claims without independent verification — GPTHuman has no published accuracy audits, Originality.AI’s 5.0 update showed why vendor claims need receipts — so this comparison labels every performance statement by source and invents none.
Quick verdict
A publisher screening freelancers or a team gating content before clients see it should pay for Originality.AI: detection, plagiarism, readability, and fact-checking draw on one credit balance, Deep Scan names the sentences and suggests the ethical edit, and the vendor answers every negative review within a day. A writer whose own draft got flagged — or who wants flagged sections fixed before anyone scans them — should pay for GPTHuman: detector and rewriter in one loop from $8.25/mo annual, Shield Guard and watermark removal from the first paid tier, with the documented trade of a thin review record and an Unlimited plan that carries an asterisk.
The catch on each side
GPTHuman’s catch is proof and promises. The review base is 16 Trustpilot reviews (3.9/5) — including one reporting output that still scored 99% AI on a free detector and another describing a refused refund on an unused 12-month subscription — and zero G2 reviews at capture. The $26 Unlimited plan’s own footnote says "subject to abuse guardrails," an undisclosed cap; per-output ceilings (300–2,500 words by tier) force long documents through multiple runs that burn quota; and one reviewer’s refund dispute suggests reading the annual terms before, not after, the card swipe.
Originality.AI’s catch is the meter. Subscription credits expire monthly whether you scan or not; re-scans charge full credits even after minor edits; the 100-word scan minimum taxes short checks; extra seats run $8.62–$19.04/mo each. The October 2026 5.0 model update drew accuracy complaints and removed legacy models without refunds — proof that any detector workflow is versioned underneath you. It also does not humanize: Deep Scan explains, a human does.
When to use both
The pairing is a loop, not a choice: Originality.AI screens the draft (combined AI + plagiarism scan), GPTHuman rewrites the flagged lines, Originality.AI re-scans the result — the gate, the fix, the receipt. Budget for the re-scan’s full credits, and keep the human edit pass in the middle: rewriting substance by hand fixes what machine rewrites only mask, and it is free. On volumes under a few thousand words a month, GPTZero’s free tier can stand in for the screening half and the total cost drops to GPTHuman alone.
The one-liner
GPTHuman sells rewrites; Originality.AI sells receipts — and a publishing operation that touches client work eventually needs both.
