## 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.

## WriteGO

WriteGO is built around a simple idea: if a draft is supposed to be grounded in sources, the sources should survive the whole trip from reading to final review. Its ChatPDF tool answers questions about a paper using retrieved excerpts and checks citations verbatim against the document, so a claim stays tied to the page it came from. Those quotes can be captured as evidence notes, and each note re-checks itself against the current document rather than drifting out of date.

From there, the Writer Agent turns selected evidence into a resumable drafting workspace. You approve an outline, the agent drafts from exactly the quotes you picked, and the work can be paused and picked up later with context intact. This keeps generated text traceable to specific sources instead of producing plausible-sounding prose with no anchor.

WriteGO also includes a review side. Integrity Review produces findings that must quote your own text verbatim — a finding whose excerpt is not found in the document is discarded before the report is shown — and the AI Detector offers explainable signals rather than a single opaque score. Detection is presented as supporting evidence in a review workflow, not as proof of authorship. Supporting aids such as a grammar checker, rewriter, summarizer, paraphraser, translator, and citation generator round out the toolkit, and credits are only charged on successful runs.

**Pricing & Plans:** Free tier with credits (up to 90 credits per month via daily check-in); Pro at $19.9/month with 300 credits; Premium at $29.9/month with unlimited usage and 800 credits/month; a Lifetime plan at a one-time $599. Extra credit packs range from 650 credits for $14.99 to 10,000 credits for $179.99.

- **Page-cited research reading:** The ChatPDF tool answers questions about a paper using retrieved excerpts and verifies citations verbatim, so answers stay tied to a specific page.
- **Writer Agent drafting workspace:** Turn an approved outline and selected evidence into a draft in a resumable workspace that carries your quotes forward without pasting blind.
- **Integrity Review on your own text:** Findings must quote your document verbatim and are discarded if the excerpt cannot be found, so every flag points to something you can check.
- **Explainable AI detection:** The AI Detector surfaces review signals you can inspect rather than a single black-box percentage, and is framed as supporting evidence.
- **Full revision toolkit:** Grammar checker, rewriter, summarizer, paraphraser, translator, citation generator, and scholar search support the writing and revision stages.

**Strengths:** Citations are checked verbatim against the source with page numbers retained; Integrity findings must quote your actual text, which keeps reviews verifiable; Writer Agent is resumable, so long documents can be built across sessions; Failed work is not billed and unlimited plans stay unmetered

**Limitations:** Credit accounting adds a layer of planning on top of writing; Detection is presented as supporting evidence, so it cannot conclusively settle authorship questions; Best value comes from the workflow as a whole rather than any single tool used alone
