## AI/ML API

AI/ML API is a developer-first aggregation layer for generative AI. Instead of signing up with each model vendor separately, you get a single universal endpoint plus an OpenAI-compatible SDK, so existing code that points at OPENAI_API_KEY, ANTHROPIC_API_KEY or GEMINI_API_KEY can be redirected to a single AIML_API_KEY and switch between models without rewriting integrations. The catalogue spans chat and reasoning models, code models, image and video generators, text-to-speech and music models, embeddings, OCR, moderation and image-to-3D pipelines.

Beyond raw models, the platform ships an MCP tool surface with 1,000+ connectors covering web search, YouTube transcripts, X/Twitter scraping, LinkedIn jobs, Reddit research and marketing/SEO data, which lets agent builders combine model reasoning with live external data. A routing layer called Jev Router automatically sends simple tasks to cheap, fast models and reserves frontier models for hard work, with the vendor claiming automatic cost reductions of up to 50%. Usage is metered per token, image, second of video or second of audio, with the company stating no markup over going direct to the provider.

The service targets startups and production engineering teams as well as enterprises. Self-serve accounts top up from a small minimum balance and pay for exactly what they consume, while larger organisations can request custom pricing, dedicated servers, private model deployments and higher rate limits with a dedicated account manager. Privacy documentation states that customer inputs are not used to train or fine-tune models.

**Pricing & Plans:** Pay-as-you-go with credits you can top up from around $20, billed per token, image, video second or audio second with a stated 0% markup over provider list prices. An enterprise tier with custom pricing, dedicated servers, private models and unlimited rate limits is available on request.

- **Unified multi-provider endpoint:** Call chat, code, image, video, audio, music, embedding, OCR and 3D models from 70+ providers through one API key and one SDK.
- **OpenAI-compatible integration:** Point existing OpenAI, Anthropic or Gemini SDK code at AI/ML API and swap models by changing the model string rather than the integration.
- **Jev Router cost optimisation:** An automatic router grades task difficulty and sends easy work to cheap models while escalating hard work to stronger ones.
- **1,000+ MCP agent tools:** Give agents live access to Google search, YouTube transcripts, X/Twitter, Reddit, LinkedIn jobs and SEO/marketing data sources.
- **Single consolidated bill:** Model calls and agent tools are metered from one balance with per-category usage receipts for tokens, images, video and audio.

**Strengths:** Very broad model catalogue behind one credential and one invoice; Drops into existing OpenAI-style code with minimal changes; MCP tool library adds research and data capabilities beyond raw models; Stated zero markup makes price comparison against direct providers straightforward

**Limitations:** You depend on a third party in the request path, so platform incidents affect all providers at once; Cost predictability requires active monitoring of per-token and per-second metering; Some cutting-edge model availability can lag the direct provider release

## 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.
