## 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.

## UserAPI.ai

Midjourney has no official public API, so teams that want image generation inside their own products usually need a workaround. UserAPI.ai fills that gap as an independent, unofficial API: it accepts a prompt and returns generated images, exposing the familiar Midjourney methods as REST endpoints you can call from your backend.

There are two ways to generate. With your own Midjourney account you add a Discord token once and pay Midjourney for your plan; UserAPI access costs $0.04 per request or $25 per month, and this route is cheaper above a few hundred images a month and supports speed mode and multiple accounts. With UserAPI Cloud you need no Midjourney subscription and no Discord token — Generations run on UserAPI's accounts at $0.08 per image, with failed tasks refunded automatically, which is a fast way to test.

The service supports the core Midjourney toolkit: Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint. It ships documentation, code examples for Python, Node.js and PHP, and no-code integrations for n8n and Make.com. It is explicitly not affiliated with Midjourney Inc., so evaluate the account and reliability risks of unofficial access before building it into production.

**Pricing & Plans:** UserAPI.ai offers a free pack of 50 requests with no card. Using your own Midjourney account costs $0.04 per request or $25 per month (or $67.50 per quarter and $246 per year), while UserAPI Cloud runs on UserAPI's accounts at $0.08 per image, a 60% discount off the $0.20 launch rate, starting from $3 (about 37 images), with failed tasks refunded automatically.

- **Full Midjourney method coverage:** Call Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint through a REST API for scripted image generation.
- **Cloud generation without Discord:** Generate without a Midjourney subscription or Discord token by running on UserAPI Cloud accounts, with failed tasks refunded automatically.
- **Multi-account admin panel:** Manage multiple image generation accounts, schedules and keys from a single admin panel.
- **Code examples and no-code integrations:** Ready code samples for Python, Node.js and PHP, plus official integrations for n8n and Make.com automations.
- **Free pack and flexible plans:** Start with a free pack of 50 requests and move to pay-per-request or monthly plans as volume grows.

**Strengths:** Brings Midjourney image generation into your own app without an official API; Cloud option works with no Midjourney subscription and no Discord token; Covers the main Midjourney methods, including Inpaint, Blend and Animate; Code examples for Python, Node.js and PHP plus n8n and Make.com integrations

**Limitations:** It is an unofficial API and is not affiliated with Midjourney, so it depends on platform behavior it does not control; Using your own Midjourney account still requires a Midjourney subscription and a Discord token; Because it relies on Discord accounts, automated usage carries account-risk considerations; Cloud pricing is per image and can add up at high volume
