## 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.

## Lkin

Lkin takes the daily friction of running several websites and compresses it into a single workspace. Instead of keeping separate bookmarks, admin URLs, and analytics tabs, you connect your sites once and get a dashboard where each property's status, performance, and access shortcuts live together. Fast CMS access is the practical centerpiece: the goal is to get into a site's admin quickly, with a browser extension carrying that capability into the tabs you already have open.

Beyond access, Lkin folds in the diagnostic layer most site owners only use occasionally. PageSpeed and website diagnostics run against your connected properties so performance regressions and health issues are visible rather than buried. An AI advisor sits on top of that data, reading the diagnostic output and recommending what to fix or improve, which is useful when the raw scores raise questions but not answers.

Because it targets people juggling more than one site, multi-site organization and team collaboration run through the product rather than being add-ons. The published model is freemium with a free trial and paid tiers, though we recommend confirming current plans directly, since the site was temporarily unreachable during our review.

**Pricing & Plans:** Listed as freemium with a free trial and paid plans. Exact tiers and prices could not be confirmed at review time because the site was temporarily unreachable, so check the official pricing page for current numbers.

- **Multi-site management dashboard:** Group every site you manage into one workspace with status at a glance, instead of bookmarking separate admin logins and analytics dashboards.
- **Fast CMS access:** Reach the CMS or admin panel of stored sites without hunting for credentials, driven partly by a browser extension that keeps access one click away.
- **PageSpeed and site diagnostics:** Run PageSpeed and website diagnostics from the same place you manage sites, so performance and health issues surface alongside the site they belong to.
- **AI advisor:** An AI advisor reviews your site data and diagnostics to suggest improvements, helping translate technical findings into concrete next steps.
- **Team collaboration:** Share sites and findings with colleagues so audits, fixes, and performance work are not siloed in one person's browser history.

**Strengths:** Brings multi-site access, diagnostics, and AI advice into one workspace; Fast CMS access reduces the friction of logging into sites you manage often; PageSpeed and diagnostics sit next to the site they describe, not in a separate tool; An AI advisor turns raw diagnostic scores into suggested next steps

**Limitations:** The site was unreachable at audit time, so we could not verify current pricing tiers; Managing many connected sites means you must configure access for each one; Diagnostics are only as useful as the sources they pull from, so setup quality matters; Requires installing a browser extension and connecting accounts to get full value
