## Crazyrouter

Crazyrouter positions itself as a unified access layer for AI models. Rather than holding accounts with a dozen providers, you create one API key in the console and route chat, image and video requests through a single endpoint. The platform is explicitly compatible with the OpenAI, Anthropic and Gemini request formats, which means the migration path is usually a one-line change: point your SDK's base_url at Crazyrouter, swap in the key, and start calling. Existing code structure stays intact, and teams can move to the gateway first and then shift individual model choices over gradually.

The advertised catalogue spans mainstream frontier models alongside Chinese and video-generation models — Claude, GPT, Gemini, DeepSeek, Qwen, Kimi, MiniMax, Kling and Sora are among the names it highlights. Pricing is published per model and sorted by input cost, and the site says its rates run below official list pricing thanks to public discounts layered on pay-as-you-go billing. Because billing is metered, costs track real usage rather than fixed seat fees.

On the infrastructure side, Crazyrouter markets multi-node smart scheduling that picks a faster path per request, redundant links and failover designed to absorb a single point of failure, and centralised quotas so calls, prices and limits are visible in one place. It also publishes developer documentation and a model pricing view. Two caveats matter: the platform openly states it is an independent third party with no official authorisation, sponsorship or endorsement from the brands whose models it resells, and that brand names appear only to identify compatible models.

**Pricing & Plans:** Pay-as-you-go / metered billing with no subscription mentioned. Publicly listed per-model rates sorted by input price, described as below official pricing due to standing discounts. Supports Chinese yuan payment, invoicing, and one balance that covers chat, image and video models. Credits are consumed according to the model selected and usage volume.

- **One key, many models:** Create a single API key and call hundreds of text, image and video models without managing separate accounts at each provider.
- **OpenAI/Anthropic/Gemini compatible endpoints:** Requests follow the common formats, so existing SDKs and CLI tools (including Claude Code and Codex CLI) work after changing only the base URL.
- **Published per-model pricing:** A pricing view lists popular models sorted by input cost and links straight to a filtered price page, making cost comparison straightforward.
- **Smart multi-node routing:** Multiple nodes schedule requests dynamically to reduce wait time, with redundant links and failover to limit the impact of any single outage.
- **Centralised quotas and billing:** Calls, prices and limits are managed in one console, with pay-as-you-go metering, CNY payment and invoice support.

**Strengths:** A single key and base URL replace juggling accounts across many providers; Request formats match OpenAI, Anthropic and Gemini conventions, so switching is usually a one-line change; Per-model pricing is published and sortable, which makes cost comparison easy; Supports CNY payment and invoicing, useful for teams that need local procurement

**Limitations:** It is an unofficial third-party reseller, so you depend on an intermediary rather than a provider's own account and SLA; The site's advertised model count is inconsistent (300+ and 600+ both appear), so verify specific models before relying on them; As an aggregator, availability and exact pricing for any model can change without the notice you'd get directly from a vendor

## 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.
