## 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.

## ModelsLab

ModelsLab is an API-first platform for teams that need many kinds of generative AI without managing many vendors. It aggregates more than 10,000 models spanning text-to-image, image editing and inpainting, upscaling, text-to-video and image-to-video, text-to-speech, voice cloning, music and sound effects, 3D generation, and chat or reasoning LLMs. All of these sit behind one API key and a unified JSON schema, so an app can start with one model and scale to others without changing its integration.

The typical workflow is browse, test, then build. You search the model library by task, try prompts in a playground to compare outputs, and once a model fits, you call it from your application with a single REST key or through the provided SDKs, CLI, and MCP server. That agent-friendly design means tools such as Cursor, Claude Desktop, Windsurf, or VS Code can invoke image, video, voice, and reasoning tools directly. Production features include request-by-request logging, webhooks for long-running jobs, and reported 99.9% uptime.

Beyond calling hosted models, ModelsLab lets you train your own models on its GPUs, run open-source models unlimited on shared capacity, or reserve a dedicated GPU for consistent throughput. Pricing starts at $21 per month with an unlimited open-source tier from $149 per month, and dedicated GPUs from $249 per month, making it a fit for startups prototyping as well as teams shipping AI features at scale.

**Pricing & Plans:** Free tier available; standard plans start at $21 per month, unlimited open-source generation runs from $149 per month, and dedicated GPUs start at $249 per month. Enterprise and custom training options are available on request.

- **10,000+ models, one API:** Access image, video, audio, 3D, and text models through one API key and a unified JSON schema, instead of juggling multiple vendors.
- **Playground and comparison:** Browse 10,000+ models by task, compare outputs, test prompts in a playground, then call the model from your app with the same integration.
- **Shared or dedicated GPUs:** Run open-source models on shared infrastructure, or reserve a dedicated GPU for predictable throughput and unlimited generations.
- **Model training:** Train fine-tunes on platform GPUs, clone voices, and customize models to fit specific products, brands, or styles.
- **MCP, SDK, and CLI:** Connect via a Model Context Protocol server, type-safe SDKs, or a CLI so AI editors and agents can call generation tools without glue code.
- **Request logging and webhooks:** Track every request with status and latency, and receive webhooks when longer video or audio jobs finish.

**Strengths:** One API key and unified schema across image, video, audio, 3D, and LLM models; Large 10,000+ model catalog with a playground for comparing outputs before you code; MCP server, SDKs, and CLI make it easy to plug into AI coding agents and automation
