## 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.

## InterviewPrep AI

InterviewPrep AI is a Chrome extension that turns a normal video call into an interview practice and support environment. Once installed, it layers an AI interview copilot onto Google Meet, Zoom, Microsoft Teams and comparable platforms, listening to the conversation and producing live transcription, structured notes and coaching as you go.

The extension leans on three ideas. First, real-time feedback: as you answer practice questions, the AI evaluates your responses and suggests improvements, closing the gap between rehearsal and readiness. Second, tailored simulations: it generates industry-specific questions so a software engineer and a sales candidate are not drilling the same generic list. Third, personal insight: it offers tips on delivery, structure and how to organise scattered thoughts into a coherent answer, plus a helper that captures coding questions from an active editor.

It is a third-party tool. The listing is published by an independent developer and marketed under the InterviewPrep AI name; it is not made by Google, Zoom or Microsoft, even though it runs inside those platforms. At review time the extension had around 3,000 users with a 4.6-star average from 21 ratings and a June 2026 update, indicating a maintained but still growing product. It is free to install with in-app purchases, and browser-based delivery means it is best suited to candidates interviewing on supported meeting platforms.

**Pricing & Plans:** InterviewPrep AI is free to install from the Chrome Web Store and offers in-app purchases for extra capability. Exact upgrade prices were not verifiable at review time — check the listing and the developer's site for current terms.

- **Real-time answer feedback:** The AI evaluates your spoken answers as you practise, giving constructive notes so you can tighten responses before the real interview.
- **Tailored practice simulations:** Generates industry- and role-specific questions to recreate realistic interview scenarios for technical, behavioural or situational rounds.
- **Live transcription and summaries:** Works alongside Google Meet, Zoom and Microsoft Teams, capturing the conversation and turning it into structured, reviewable notes.
- **Coding challenge support:** A one-click helper captures coding questions from an active editor so you can get support during technical practice.
- **Multi-device session access:** Share a session to follow the same practice run from a phone or tablet as well as your desktop.

**Strengths:** Runs inside the meeting platforms candidates already use, with no separate app to learn; Combines live transcription, real-time feedback and practice question generation in one extension; Lightweight install (about 2 MB) with a solid 4.6-star rating at review time; Multi-device session sharing is handy for reviewing practice on a phone or tablet

**Limitations:** Feedback quality depends on audio transcription accuracy, which can degrade with poor microphones or heavy accents; It is a browser extension, so it is tied to supported meeting platforms and Chrome rather than working everywhere; In-app purchases are required to unlock the full experience, and we could not verify exact pricing at review time
