## AI Reply

Most email assistants force you to leave the compose window, paste your draft into a chat box and move text back and forth. AI Reply takes the opposite approach: it lives in the Gmail toolbar as a Chrome extension, so the generation happens next to the message you are actually working on. From there you can start a brand-new email, produce a reply to an existing thread, or rewrite something you already typed.

Control is the interesting part of the product. Before generating, you set the context you want the AI to write from, choose a tone that fits the relationship, and pick a target length. That combination lets the same assistant produce a terse follow-up to a procurement contact and a warmer note to a returning client. Multilingual output extends the same idea to correspondence that crosses language borders.

AI Reply is published by Whirr Crew, a software and AI delivery company based in Prague that also builds custom AI solutions. The extension has a good standing on the Chrome Web Store, a modest but consistent user base, and a privacy posture stating that user data is not stored or shared with third parties and is not sold. It suits individual professionals, freelancers, sales and support staff who want faster, cleaner email without adopting a heavy platform.

**Pricing & Plans:** Freemium. The Chrome Web Store listing indicates a free tier with paid upgrades available. The publisher does not maintain a public pricing page, so current plan names, limits and upgrade prices should be checked from within the extension after installation.

- **Draft and reply in seconds:** Generate a complete email or a contextual reply to the message you have open, so you can move from blank page to sendable draft in seconds.
- **Adjustable context, tone and length:** Set the context, tone and target length before generating, which keeps output aligned with a formal negotiation or a friendly check-in.
- **Multilingual writing:** Ask for emails in a range of languages and communicate confidently with international clients, partners and colleagues.
- **Inline Gmail workflow:** The assistant loads inside your Gmail toolbar, so there is no copy-pasting between tabs and no third-party dashboard to visit.
- **Ad-free, low-distraction interface:** The publisher states the extension shows no advertising and keeps the interface minimal so composing stays uninterrupted.

**Strengths:** Works where the work happens, inside Gmail, with no copy-pasting between tools; Tone, length and context controls make output adaptable instead of one-size-fits-all; Multilingual generation is useful for international correspondence; Published by an established software and AI company with a clean Chrome Web Store record

**Limitations:** Requires a Google Chrome or Chromium-based browser; it is not available as a standalone web app; The dedicated product domain is not live, so plan details and terms are only visible inside the extension experience; Best results still depend on a quick review pass, since tone assumptions can occasionally miss the mark; Gmail is the primary supported surface, so other mail clients are not covered

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.
