## AIHumanize.com

AIHumanize.com addresses a narrow but persistent problem: content drafted by language models that reads flat or gets flagged as machine-written. The interface is a plain text box with a file upload option, two model families shown on the page (Falcon and Maestro, each in multiple versions), and a writing-style selector. After rewriting, you can run a built-in checker that reports signals such as perplexity, sentence-length variation, and length normality — the same statistical traits detectors use to judge whether text is human. The company has since launched a Version 2 of its models and claims a 99.8% detector pass rate across more than 1.28 billion words processed monthly.

The product bundles two jobs that usually require two subscriptions. The humanizer rewrites your text, and the checker estimates how AI-like it still looks, supporting PDF, Word, and plain-text inputs and claiming coverage of output from ChatGPT, GPT-3.5/4, and Gemini. The site also emphasizes SEO friendliness — it keeps important keywords rather than substituting odd synonyms — and avoids introducing grammar errors or misplaced vocabulary, which are the two things that tend to expose machine-rewritten copy in a search context.

On pricing, there is a genuine free entry point: the site states you can rewrite up to 400 words at no cost, and the input field accepts up to 21,000 words per run. Paid plans are promoted on the Pricing and Earn pages for heavier volume and additional models. Because the model lineup and credit structures change quickly, treat specific prices as something to confirm on the site rather than a fixed figure.

**Pricing & Plans:** Freemium. A free tier rewrites up to around 400 words per run with no signup required, and the editor accepts up to 21,000 words of input. Paid plans are advertised for higher volume and access to the newer Maestro and Falcon model versions; check the Pricing page for current rates.

- **AI text humanizer:** Rewrites machine-drafted prose into natural, varied sentences that preserve your key terms and intended search intent.
- **Built-in AI detector:** Scores your text on perplexity, sentence-length variation, and length normality, and supports PDF, Word, and plain-text input.
- **Multiple model versions:** Offers Falcon and Maestro model families in several versions so you can trade off speed against rewriting depth.
- **Writing style control:** Lets you pick a target style so the rewritten text matches the tone of the publication or channel you are writing for.
- **Keyword-preserving rewrite:** Keeps important SEO terms in place instead of swapping them for synonyms, so rankings are less likely to suffer.

**Strengths:** Free tier handles short passages without requiring an account; Humanizer and detector live in one place, so you can rewrite and immediately check; Keyword-preserving rewrite is designed with SEO content in mind; Supports file uploads in PDF, Word, and text formats

**Limitations:** No tool can guarantee every AI detector will pass a given text; Accuracy of detector scores is inherently probabilistic and should not be treated as proof; Newer model versions and higher usage sit behind paid plans, so costs rise with volume

## Grammarly

Grammarly is the world's most widely deployed AI writing and communication platform, trusted by more than 40 million daily users and 50,000 organizations including Atlassian, Databricks, and Zoom. Operating as a persistent overlay across over 500,000 web applications, desktop programs (Windows and macOS), Microsoft Office, Google Docs, and iOS/Android keyboards, Grammarly analyzes text in real time to eliminate grammatical errors, streamline wordy phrasing, and calibrate tone to match the writer's intent. Following its corporate evolution under the Superhuman Platform umbrella alongside Superhuman Mail and Coda, Grammarly has expanded from a personal proofreader into an enterprise-grade proactive AI communication suite.

In 2026, Grammarly goes well beyond red-underline spellchecking with a suite of specialized AI Agents and document integrity tools. Writers can invoke purpose-built agents—including AI Grader, Citation Finder, Reader Reactions, and Paraphraser—alongside generative AI drafting directly inline where they work. To address academic and professional transparency in the generative AI era, Grammarly offers built-in Plagiarism Detection, an AI Detector, and Grammarly Authorship, which tracks how a document was constructed by automatically categorizing text as human-typed, pasted from external sources, or generated/modified with AI. For teams, Grammarly enforces organizational consistency through custom Style Guides, Brand Tones, reusable Snippets, and Knowledge Share.

Grammarly simplified its subscription structure by consolidating its legacy individual 'Premium' and team 'Business' offerings into a single unified tier: Grammarly Pro. The Free plan ($0/month) covers essential spelling, punctuation, basic tone visibility, and 100 generative AI prompts per month. Grammarly Pro is priced at $12/member/month when billed annually ($144/year) or $30/member/month when billed monthly ($60 quarterly), unlocking unlimited personalized fluency suggestions, full-sentence rewrites, tone adjustment, citation formatting, plagiarism and AI detection, 1 team style guide, and 2,000 generative AI prompts per member each month. Large organizations opt for Grammarly Enterprise (available with Superhuman Go) for unlimited AI prompts, SAML SSO, SCIM provisioning, Data Loss Prevention (DLP), and Bring Your Own Key (BYOK) encryption.

**Pricing & Plans:** Free plan ($0/month) includes core grammar and spelling checks, tone detection, and 100 generative AI prompts/month; Grammarly Pro costs $12/member/month billed annually ($144/year, or $30/month billed monthly) with full-sentence rewrites, plagiarism/AI detection, team style guides, and 2,000 AI prompts/month, while Enterprise offers custom pricing with unlimited AI prompts and BYOK security.

- **Ubiquitous Inline Rewriting & Tone Calibration:** Works natively inside Chrome, Safari, Firefox, Edge, Windows, Mac, Google Docs, MS Office, and mobile keyboards to flag grammar mistakes, rewrite tangled sentences, and shift tone toward confident, empathetic, or executive registers.
- **Specialized AI Agents (AI Grader, Citation Finder & Reader Reactions):** Deploys contextual AI agents that predict how a target audience will react to a draft, locate credible supporting citations, grade essays against rubric criteria, and generate drafts using up to 2,000 monthly prompts on Pro.
- **Grammarly Authorship, AI Detector & Plagiarism Checker:** Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.
- **Team Style Guides, Brand Tones & Knowledge Share:** Enables teams on Pro and Enterprise plans to codify company terminology, ban deprecated jargon, enforce inclusive language, insert shared Snippets, and surface internal company definitions inline.
- **Enterprise Security, DLP & Superhuman Platform Governance:** Protects organizational data with SOC 2 Type 2 attestation, SAML SSO, SCIM lifecycle management, Confidential Mode, Data Loss Prevention controls, Audit Logs API, and customer-managed BYOK encryption.

**Strengths:** Frictionless cross-platform integration works inside virtually every browser, desktop app, email client, and mobile OS without copy-pasting into a separate chatbot.; Consolidating Premium and Business into Grammarly Pro ($12/member/month annual) gives individuals and small teams access to style guides, analytics, and plagiarism/AI detection in one plan.; Grammarly Authorship provides a constructive, transparent audit trail for students and writers to demonstrate human writing integrity alongside responsible AI editing.; Mature enterprise security posture featuring BYOK encryption, Data Loss Prevention, and granular application/domain blocklists.

**Limitations:** Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).; Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.; Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.
