## Checkstep

Checkstep is built for the teams responsible for keeping user-generated and professional content safe: trust and safety, content operations and compliance leaders at gaming, marketplace, streaming, dating, social and review platforms. Rather than a single classifier, it provides an integrated platform where policy is defined once and then enforced consistently across every content type and language.

At its core is a configurable policy engine covering the major abuse categories. You set what is and is not allowed on your platform, and Checkstep's workflow and automation layer applies those rules. An AI marketplace gives access to leading moderation models so teams can determine which fits their policy and content needs, test alternatives and swap models without re-engineering the whole pipeline. Moderation itself blends automated scanning from ModBot with human review, letting specialists focus on the highest-risk or most nuanced cases.

Compliance is a first-class feature: the platform centralises the data required under the EU Digital Services Act and can generate transparency reports for European users on demand. Checkstep reports a 90% reduction in human moderation costs, 78% faster moderation and 98% detection accuracy, and works with handpicked BPO and technology partners for customers who need extra capacity. Public case studies include Trustpilot, JustGiving, Star Stable and 123 Multimedia.

**Pricing & Plans:** Free trial available; full pricing is provided on request after a demo, with costs depending on content volume and deployment scope.

- **Multi-format moderation:** Scan and moderate text, images, video and audio in more than 100 languages from one integrated platform.
- **Configurable policy engine:** Define your own rules across all major abuse categories, then let the workflow and automation layer enforce them consistently.
- **AI model marketplace:** Access leading moderation models, test which fit your policy, and swap providers seamlessly without rebuilding pipelines.
- **Human-in-the-loop workflows:** Blend automated ModBot screening with expert review so your team focuses on the cases that matter most.
- **DSA transparency reporting:** Centrally manage regulatory data and generate transparency reports for your European users instantly.

**Strengths:** One platform covers text, image, video and audio in over 100 languages; Policy engine plus model marketplace lets you tailor and swap AI models without rework; DSA transparency reporting is built in, easing regulatory compliance; Documented case studies with named customers and published efficiency figures

**Limitations:** Pricing is not published, so you need a demo and quote before budgeting; Enterprise-oriented setup means it is not aimed at small communities or solo developers; Effective deployment still requires staff to define policy and manage human review queues

## 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.
