## GPTinf

GPTinf positions itself as a 'check, fix, submit' workflow. Instead of stitching together several separate services, it bundles an AI humanizer, an AI detector, a paraphraser, a plagiarism checker, a readability checker and a grammar checker into a single dashboard. The humanizer is the centerpiece: it rebuilds sentence rhythm and phrasing to strip out the patterns that detectors often flag, and it includes a 'Freeze' option so you can lock specific terms, names or jargon that must stay untouched.

The detection side is unusually transparent. Rather than giving a single score, GPTinf's detector cross-checks text against eight systems and shows segment-level results, so you can see which parts of a paragraph are most likely to be flagged. The plagiarism checker traces flagged sentences back to their source URLs, and the readability checker reports a Flesch-Kincaid level with hard-to-read passages highlighted.

The platform is aimed at students, educators, freelancers, marketers and business writers. It offers writing modes so you can shift tone or reading level to match your audience, and it keeps meaning, register and tone intact during rewriting. GPTinf works entirely in the browser, advertises a free and unlimited detector, and sells paid plans that scale the number of humanizer and paraphraser words available per month.

**Pricing & Plans:** Freemium with a free tier that includes an unlimited AI detector, plus paid monthly subscriptions. Plans shown on the site are Lite at $4.99/month (5,000 humanizer words and 2,500 paraphraser words), Pro at $12.49/month (25,000 humanizer words and 12,500 paraphraser words), and Unlimited at $29.99/month with no caps on humanizer or paraphraser words.

- **AI Humanizer with Freeze:** Rewrites AI-style text to read more naturally and rebuilds sentence rhythm, with a Freeze option that locks the words, names or phrases you need to keep exactly as written.
- **Multi-System AI Detector:** Cross-checks your text against eight detection systems at once and shows a segment-level, color-coded breakdown so you can see which sentences carry the highest risk.
- **Paraphraser with Writing Modes:** Rephrases text in different modes so you can adjust tone, register or wording while locking important terms and preserving the original meaning.
- **Plagiarism Checker:** Scans your text against web sources, returns a plagiarism percentage, flags matching sentences and traces each match back to its source URL.
- **Readability & Grammar Checkers:** Reports a Flesch-Kincaid readability score with difficult passages highlighted, and catches contextual grammar errors you can fix with a single click.

**Strengths:** Six related tools — humanizer, detector, paraphraser, plagiarism, readability and grammar — in one dashboard; Detector shows eight-system, segment-level results rather than a single opaque score; Freeze option locks names, terms and jargon so rewriting does not distort key wording; Free tier includes unlimited AI detection

**Limitations:** Paid monthly subscriptions cap humanizer and paraphraser word counts on the Lite and Pro plans; Central features rely on detection tools, whose scoring can change as those systems update; No guarantees that text will pass any specific institution's or platform's detection policy

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
