## 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.

## Moonbeam

Moonbeam positions itself as the AI writing assistant for people who have to produce long-form content and keep stalling on the first sentence. Instead of handing you a single generic block of text, it walks a writer through a structured workflow: drop in jumbled notes or a short prompt, let Luna build a coherent outline, then expand that outline into structured paragraphs you can edit inside a rich text editor.

The editor is where Moonbeam spends most of its effort. You can paraphrase or improve any highlighted passage, activate a Boss Mode-style full rewrite, embed links and images, and share public drafts. GPT-4-powered Smart Chat sits beside the document so you can ask questions, request changes and generate whole posts directly from the conversation. Content Cluster extends the same idea to a single keyword, producing more than ten related content ideas plus outlines and posts you can organize into folders.

Collaboration is handled through a Google Docs-style shared editing mode aimed at AI-generated drafts, and a Custom Style Generator lets you write in the voice of famous authors, comedians or politicians. Moonbeam offers a free plan and a paid Pro tier backed by a money-back guarantee, with Pro unlocking unlimited long-form writing, the Wizard and custom styles.

**Pricing & Plans:** Free plan available; Moonbeam Pro is the paid tier and includes a 100% money-back guarantee. Pro unlocks unlimited long-form and social writing, the Moonbeam Wizard and the custom style generator.

- **Moonbeam Wizard and Luna:** Turn raw notes into an outline and then into written paragraphs, or prompt Luna with a single phrase to receive a full first draft.
- **GPT-4 Smart Chat:** A chat layer inside the editor that answers questions, applies precise edits to highlighted text and generates posts from the conversation.
- **Content Cluster:** Enter a keyword or prompt and receive 10+ content ideas with one-click outlines and full blog posts, organized into folders.
- **Custom Style Generator:** Write in the distinctive voice of authors, comedians or public figures with a simple style prompt.
- **Collaboration and rich editor:** Google Docs-style multi-user editing, paraphrase and improve tools, media embeds and shareable public drafts.

**Strengths:** Purpose-built for long-form content rather than short ad copy; Note-to-outline-to-draft workflow reduces the blank-page problem; Editor integrates GPT-4 chat, rewriting and media embeds in one place; Free plan plus money-back guarantee on the Pro tier lowers risk

**Limitations:** Output still needs a real human edit for accuracy and citations; Some templates such as product updates and Twitter threads are marked beta; Long-form focus means it is overkill for very short social captions
