## 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.

## WebFill

WebFill is an AI browser extension built around repetitive web work: filling forms, completing surveys, entering data, answering multiple-choice questions and drafting emails. It uses advanced AI models to read what is on a page and act on it, and it can also work from a PDF, pasted text or the intelligent instruction setup you save for each website.

A distinguishing feature is WebFill Vision. Designed for students and professionals, it lets you capture any part of your screen and get instant answers — the company describes it as operating within your browser for tasks such as MCQs and online assessments. The extension also includes a chatbot for general questions and email assistance that can generate or respond to messages from your inbox.

Pricing is tiered. The Free plan covers 1K words per month, basic support, basic AI models, automated form filling and 20 Vision uses per month. The Standard plan at $7.99/month raises that to 100K words and 400 Vision uses with priority support and access to the most powerful models, while the Premium plan at $19.99/month offers 250K words, 1,000 Vision uses and enterprise-level data security. WebFill reports over 1K active users, 8K+ customers and millions of Vision launches and chats, and it also runs an affiliate program.

**Pricing & Plans:** Freemium. Free plan: 1K words/month, basic models, 20 Vision uses. Standard: $7.99/mo (100K words, 400 Vision uses). Premium: $19.99/mo (250K words, 1,000 Vision uses, enterprise-level data security). Annual billing saves 20%.

- **Automatic form filling:** WebFill detects fields on a page and completes forms, surveys and data-entry screens automatically, learning per-site instructions over time.
- **Screenshot analysis with Vision:** WebFill Vision captures any part of your screen and returns answers, aimed at multiple-choice questions, online assessments and on-screen content.
- **AI email generation:** Generate or reply to emails straight from your inbox by pressing the WebFill button and letting the AI draft the response.
- **Task and data-entry automation:** Upload a PDF or paste text and let WebFill handle repetitive data entry, MCQ solving and survey completion with saved instructions per website.
- **Tiered plans and models:** Choose from free, Standard and Premium plans with increasing word budgets, Vision usage and access to more powerful AI models.

**Strengths:** Automates genuinely tedious work like forms, surveys and data entry; WebFill Vision reads on-screen content for quick answers; Saves per-website instructions so repeated tasks get faster over time; Handles email drafting and replies from directly inside your inbox

**Limitations:** Vision features aimed at exam and MCQ answering sit in a gray area with many schools' and employers' policies; Word and Vision usage are capped by plan, so heavy users may hit limits quickly; The free tier is limited to 1K words per month with basic models and 20 Vision uses
