## 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.

## HyperWrite

HyperWrite positions itself as a predictive AI writing assistant that follows you across the web. Through its Chrome extension, it offers TypeAhead suggestions that complete sentences as you type inside Gmail, Google Docs, and other web editors, alongside AutoWrite for generating paragraphs from a short instruction. An email responder drafts full replies from a few keywords, which is a common productivity win for people who live in their inbox.

Beyond the assistant itself, the product ships a large library of pre-built tools covering rewriting, summarization, explaining complex topics in plain language, speeches, and more. Users can also assemble custom AI tools that chain steps together for repeated workflows. HyperWrite Scholar adds a research layer by searching scholarly articles and papers, so generated text can be grounded in current, citation-backed information rather than the assistant's memory alone.

Pricing is subscription-based with a free entry point alongside paid tiers. Paid plans increase the monthly AI message allowance, unlock custom personas that mimic your writing style, and give unlimited TypeAhead suggestions. Higher tiers remove the message cap entirely and provide early access to experimental writing and agent features.

**Pricing & Plans:** Freemium. A free tier introduces the assistant and a limited message allowance; Premium is listed around $19.99/month with 250 AI messages, citations, real-time info, and 3 custom personas; Ultra around $44.99/month adds unlimited AI messages, 10 personas, and early access to experimental features. Annual billing is available at a discount.

- **TypeAhead autocomplete:** Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
- **AutoWrite and rewriting tools:** Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
- **Citation-backed research:** HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.
- **Email responder:** Turn a few keywords into a complete, ready-to-send email reply without switching tabs.
- **Custom AI tools:** Build your own reusable AI tools that chain prompts and steps for recurring workflows.

**Strengths:** Works directly inside the browser via a Chrome extension, so no app switching; Combines writing help with citation-backed research in one subscription; Large catalog of ready-made tools plus custom tool building; Essays, emails, and rewrites share one account and one message allowance

**Limitations:** Message caps on lower tiers can be limiting for heavy users; Best autocomplete experience depends on using the Chrome extension; Full capabilities require a paid plan beyond the free allowance
