## 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.

## Humanizer.Pro

Humanizer.Pro targets the growing problem of text that reads as obviously machine-written. You paste a passage, pick a mode, and the tool rewrites it — not by swapping a few synonyms, but by restructuring sentences so the output flows like a human wrote it. The site reports 1.2M+ users, 1.5M+ words processed daily, and average human scores above 98%.

The interface is built around three usage modes — Simple, Normal, and Advanced — so you can trade speed for rewriting depth. There is also a sample button and a built-in AI detection check, letting you test the tool before committing real content. The engine is trained to handle a wide range of formats, from essays and homework answers to emails, business reports, and website articles.

Beyond humanizing, Humanizer.Pro emphasizes error-free output: the site claims results are grammatically precise, readable, and structured to pass plagiarism checkers. It supports humanizing across more than 50 languages, making it useful for international students, global businesses, and multilingual creators. The free plan allows 200 words at a time, while paid tiers lift the word limit.

**Pricing & Plans:** Freemium. The free plan covers the core humanizing features with a 200-word-per-run limit and no login required for basic use. The premium plan removes the word limit and adds extra credits and features for heavier users. Specific premium pricing is listed on the site's pricing page.

- **Three rewriting modes:** Choose Simple, Normal, or Advanced depending on how deep you want the rewrite to go — useful for balancing speed against how thoroughly the text is reworked.
- **Detector-oriented output:** The engine is tuned to produce text that scores as human on major AI detectors, and the site lists Originality.AI, GPTZero, ZeroGPT, Copyleaks, and others as targets.
- **Grammar and plagiarism care:** Output is designed to be grammatically clean and readable, and structured to pass plagiarism checks so the writing stands up in academic and professional settings.
- **50+ language support:** Humanize AI text in Spanish, French, German, Japanese, and dozens more languages, with attention to each language's natural patterns and nuances.
- **Try-before-you-use workflow:** A sample text button and an integrated AI check let you see results on your own content before running a full document through.

**Strengths:** No login needed to try the core humanizing features on the free tier; Three modes let you control how aggressive the rewrite is; Supports humanizing in 50+ languages, useful for multilingual work; Addresses both AI detection and plagiarism checks in one workflow

**Limitations:** The free plan caps input at 200 words per run, which is limiting for long documents; Promoting detector evasion can conflict with some schools' and publishers' AI policies; Quality of the rewrite varies with the source text and the mode chosen
