## 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.

## TrustDoc

TrustDoc is an AI document management and evaluation platform aimed at organizations that review large volumes of structured paperwork — applications, submissions, marking sheets, compliance files, and similar records. The workflow is deliberately short: upload documents, have AI analyze them, and retrieve scored, justified results, all from a single interface rather than a chain of spreadsheets and manual checklists.

The evaluation engine is the centerpiece. Documents are compared against approved templates and headers, then given AI-generated scores accompanied by written justifications that explain the reasoning behind each result. That combination matters in review-heavy environments where two reviewers can otherwise reach different conclusions from the same file. Standard and premium tiers add AI summarization, letting a reviewer scan condensed overviews of a whole batch before deciding where to spend attention.

Organization and workflow features round out the product. Folders can be shared with specific groups and team members, headers are configurable per project, and settings can be saved as reusable configurations so recurring review cycles start from a known-good setup. Pricing follows a freemium model: Basic is free with 1 project, 5 users and 5 headers; Standard is $35/month with 10 projects, 50 users per project, unlimited headers and AI summarization; Premium is $99/month with unlimited projects, 250 users per project and unlimited headers. Yearly billing saves 30%, and a custom Organization plan is available.

**Pricing & Plans:** Freemium. Basic $0/month (1 project, 5 users per project, 5 headers, AI scoring and justification). Standard $35/month (10 projects, 50 users per project, unlimited headers, adds AI summarization). Premium $99/month (unlimited projects, 250 users per project, unlimited headers). Yearly billing saves 30%; custom Organization plan available.

- **Upload, analyze and retrieve with AI:** Upload, analyze, and retrieve documents in a few clicks, with AI reviewing each file against your approved headers and templates instead of relying on manual spot-checks.
- **AI scoring:** Generate consistent numerical scores for every submission so reviewers and stakeholders can compare documents objectively rather than relying on gut feel.
- **AI justification:** AI writes the reasoning behind each score, giving you an audit trail that explains why a document passed or fell short, which is especially valuable in compliance contexts.
- **AI summarization:** Standard and premium plans condense long documents into digestible summaries, so reviewers can triage a large batch quickly before reading in depth.
- **Template and header comparison:** Compare submitted files against approved templates to catch missing sections, format drift, and incomplete headers before documents move downstream.
- **Folder sharing and reusable configurations:** Share folders with groups and team members with plan-specific user limits, and save reusable configurations so recurring review rounds start from a known setup.

**Strengths:** Free tier covers core AI scoring and justification, so you can test with real documents; Written AI justifications create an audit trail behind every score; Template and header comparison catches incomplete or off-format submissions automatically; Straightforward plan ladder that scales from 1 project to unlimited

**Limitations:** Pricing is per-month with no stated free-trial length on the highest tier; Free tier allows only 1 project and does not permit removing users; Some depth (unlimited headers, AI summarize) is reserved for paid plans; The site is JavaScript-dependent, so it can look blank if scripts are blocked
