## 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.

## TimelyGrader

TimelyGrader is built around a simple premise: AI alone should not decide a grade. The platform generates first-pass grades and draft feedback for student work, but always shows the reasoning behind each suggestion and requires an instructor or teaching assistant to review and confirm before anything is returned to students. That human-in-the-loop design is what the company says makes AI grading both valid and reliable.

What separates it from a basic essay grader is the range of work it handles. Alongside academic essays, TimelyGrader analyses STEM technical reasoning, hand-written submissions, spreadsheets, and video presentations, including visuals, charts and tables. Instructors define the rubric — or generate one with the built-in AI assistant, Hugo — then upload assignments, review suggested scores and comments, adjust them, and release feedback.

The product is aimed squarely at higher education and institutions. It advertises use across 1,300+ institutions with 40K+ student submissions graded and 2,200+ instructors, and it is an official Instructure partner with LMS API integration, WCAG AA accessibility and FERPA compliance. A free plan lets individual educators experiment, while the Starter plan unlocks unlimited courses and bulk uploads, and institutions get admin controls, quiz and exam grading, accreditation data export and 24/7 support.

**Pricing & Plans:** Free plan (no credit card, includes rubric generation and AI grading preview), Starter at $12/month or $10/month billed annually (about 17% off), and an Institution plan with LMS integration, admin controls and accreditation data export via Contact Sales.

- **Beyond Essay Grading:** Grade essays, STEM technical writing, handwritten work, spreadsheets and video presentations against your own rubric, including visuals, charts and tables.
- **Human-in-the-Loop Validation:** Every suggested grade comes with a rationale, and the platform requires instructor or TA validation before results reach students.
- **Custom Rubrics and Hugo Assistant:** Build and generate rubrics, fine-tune AI grading, and use the Hugo assistant to draft and refine feedback.
- **Scalable Personalised Feedback:** Provide specific, personalised feedback at scale instead of reusing templates, supporting formative assessment across large cohorts.
- **LMS Integration and Compliance:** Official Instructure partner with LMS API integration, WCAG AA accessibility and FERPA compliance, plus institution-level admin controls and accreditation data export.

**Strengths:** Human-in-the-loop design keeps instructors in control of final grades; Handles essays, technical writing, spreadsheets and video, not just text; Fully customisable rubrics plus an AI rubric generator and feedback assistant; Generous free plan for individual educators to trial

**Limitations:** Higher-tier and institution plans require contacting sales rather than transparent public pricing; Every grade still needs human validation, so it assists rather than fully automating grading; Primarily designed for higher education; less suited to K-12 or non-academic training
