## 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.

## superReply

superReply is a browser extension that adds an AI reply assistant to the tools people already work in. Once installed and signed in, it appears directly inside Gmail and Outlook web inboxes, and it also works across LinkedIn, WhatsApp, Slack, Upwork and Fiverr. Instead of composing a reply from scratch you click into a message, let the extension suggest options, adjust the tone of voice to match the situation and send the version that fits.

The product is aimed squarely at people who answer the same kinds of messages all day: customer care agents, sales teams, freelancers juggling client threads and anyone who wants to clear an inbox faster. Its selling points are speed, tone matching and privacy. The extension only accesses the emails you explicitly choose to use it on, replies are not stored on superReply's servers, and the company says it applies industry-standard encryption.

The service is free to start, with up to 90 AI-powered replies per month at no cost. Paid plans remove that ceiling and unlock advanced tone controls, billed monthly or annually, and there are team plans for managing multiple seats. Each user installs the extension on their own browser with their own account so replies stay personalised, and cancellation is a one-click action from account billing settings.

**Pricing & Plans:** Freemium. Free to start with up to 90 AI email replies per month. Paid plans unlock unlimited replies and advanced tone controls, billed monthly or annually, with team plans available for multiple seats. Cancel anytime from billing settings.

- **Reply suggestions inside your inbox:** The extension appears directly in Gmail and Outlook web, so you never leave the thread you are answering.
- **Tone matching:** Pick the tone of voice that fits the situation — professional for a client, casual for a friend — and the suggestions adapt.
- **One-click smart responses:** A single click surfaces several ready-to-send reply options so you are never stuck staring at a blank compose box.
- **Works beyond email:** Beyond Gmail and Outlook, superReply integrates with Chrome, WhatsApp, Slack, LinkedIn, Upwork and Fiverr.
- **Privacy-first handling:** Replies are not stored on superReply's servers, the extension only reads emails you choose to use it on, and data is encrypted in transit.

**Strengths:** Free tier covering up to 90 AI replies every month; Lives inside Gmail and Outlook, so there is no new app to learn; Tone controls adapt suggestions to professional or casual contexts; Does not store generated replies on its own servers

**Limitations:** Requires installing a Chrome extension rather than working as a standalone web app; Advanced tone controls and unlimited replies sit behind the paid plans; Each user needs their own account, so team-wide rollout takes a little setup
