## 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.

## Smodin

Smodin bundles the tasks that students, researchers, and content teams usually spread across several subscriptions into a single workspace. The headline trio is an AI content detector, an AI humanizer, and a plagiarism checker: paste or upload a draft and the detector returns an overall AI-probability score with sentence-level highlights, the humanizer rewrites text so it reads more naturally, and the plagiarism checker scans against a large source index to flag anything that needs a citation. An AI writer and chat assistant covers drafting, outlining, and brainstorming.

Alongside those, Smodin provides a longer list of supporting utilities — a rewriter and spinner, text summarizer, language translator with broad language support, paraphrasing, and an AI watermark remover — plus a Chrome extension for using the tools without leaving the browser tab where you are writing. The workflow is consistent across tools: enter text, choose the operation, review results, and iterate, and the site reports scanning speeds under a second and support for well over a hundred languages.

The platform is positioned primarily for students, academics, and professional writers, and it says text submitted for scanning is not stored or shared. Access is via paid subscription plans, with free trials and limited free usage available so you can test the detector, humanizer, and checker before committing to a plan.

**Pricing & Plans:** Paid subscription plans with free trial access and limited free usage on several tools; pricing tiers are listed on the Smodin pricing page and cover increasing word limits, tool access, and language support.

- **AI content detector:** Scan text for AI-generated patterns with sentence-level highlighting and a plain-language verdict covering writing from models like ChatGPT, Claude, and Gemini.
- **AI humanizer:** Rewrite AI-generated text so it reads naturally and more closely matches a human voice, useful before submitting essays, articles, or client work.
- **Plagiarism checker:** Check drafts against a broad index of sources to confirm originality and surface places that need proper citation.
- **AI writer and chat:** Draft, outline, and refine content with an AI writing copilot and chat assistant that handles academic and SEO-oriented briefs.
- **Rewriter, translator and extras:** Supporting tools round out the suite, including a rewriter and spinner, text summarizer, language translator, paraphrasing, AI watermark remover, and a Chrome extension.

**Strengths:** Detector, humanizer, plagiarism checker, and writing assistant combined in one workspace; Consistent paste-and-go workflow across every tool; Broad language support and a Chrome extension for in-browser use; Fast scans with a free trial path to test before paying
