## 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.

## SiliconFlow

SiliconFlow positions itself as AI infrastructure rather than a single model. The platform aggregates a broad catalog spanning text LLMs, image generation (for example FLUX family), video, and audio models, so teams can switch or compare models by changing one parameter instead of rebuilding an integration. Requests are served through an OpenAI-compatible endpoint, meaning existing SDK code often works with only a base-URL and key swap.

Deployment is flexible by design. Developers can start on Serverless inference with pay-per-use billing and no setup, move to dedicated endpoints for isolation and throughput, or reserve NVIDIA H100/H200, AMD MI300 and RTX 4090 class GPUs when they need guaranteed capacity and predictable billing. An Elastic GPU (FaaS) tier targets bursty or spiky inference workloads, and an AI Gateway layer adds smart routing, rate limiting and cost controls across models.

The platform also covers the surrounding lifecycle: data access and processing, fine-tuning and one-click deployment of customized models, and an inference engine tuned in-house for higher throughput and lower latency. SiliconFlow states that customer data is not stored, and pricing is published per million tokens with separate input, cached-input and output rates, which makes cost forecasting relatively straightforward.

**Pricing & Plans:** Pay-as-you-go with no upfront commitment: serverless inference is billed per million tokens (separate input, cached-input and output rates) or per generated image, and pricing tables are published publicly per model. Capacity-based options include dedicated endpoints, reserved GPUs and elastic GPU deployment, typically quoted via a sales conversation. A free "Get Started" tier is offered so you can test models before committing.

- **One OpenAI-compatible API:** Access a large catalog of LLMs and multimodal models through a single endpoint, so most existing SDK code works after swapping the base URL and key.
- **Serverless, dedicated and reserved deployment:** Start with pay-per-use serverless calls, then move to dedicated endpoints, reserved H100/H200/MI300 GPUs or elastic GPU (FaaS) deployment as throughput and cost requirements grow.
- **Fine-tuning and one-click deployment:** Customize supported models on your own data and push the tuned variant to a hosted endpoint without building a training pipeline from scratch.
- **Published per-token pricing:** Transparent rate tables list input, cached-input and output prices per million tokens, plus per-image rates for generation models, making budget planning concrete.
- **AI Gateway routing and controls:** A gateway layer centralizes model access with smart routing, rate limiting and cost-control policies across providers and model families.

**Strengths:** Large multi-vendor catalog behind one OpenAI-compatible API reduces integration work; Transparent, published per-token and per-image pricing makes cost modeling predictable; Deployment options scale from serverless prototyping to reserved GPUs without a platform migration; Stated no-data-retention policy and in-house inference optimization for latency and throughput

**Limitations:** Model-specific rate details and rapid catalog changes require monitoring to keep cost models accurate; Reserved GPU and dedicated capacity pricing is sales-led rather than fully self-serve; Feature depth varies by model family, so some advanced options are not uniform across the catalog
