## 1Stroke

1Stroke takes a narrow, practical view of AI writing: instead of opening a separate chatbot and pasting text back and forth, it puts the assistant where your words already live. Its tagline sums up the pitch — "the fastest way to craft meaningful replies anywhere on the web" — and its two core actions are Reply with AI and Rephrase with AI. Because it adapts to your own words and tone, the output is intended to sound like you rather than like a generic AI voice.

Support for "all websites" is the key differentiator. Many reply assistants are tied to a single inbox or social network; 1Stroke aims to work on whatever page you happen to be on, which covers email, social comments, review responses, and support threads in one extension. Setup is quick: install the extension, sign in through the app subdomain, and the assistant appears alongside the text fields you already use.

Pricing is deliberately simple and posted publicly on the site. The Free tier includes Reply with AI and Rephrase with AI across all supported websites but with limited power. Premium is listed at $7.50 per month billed monthly and adds customization, full power, and customer support. A Teams plan carries a custom annual price with membership and permission management, personalized customization help, training, and 7/7 support. The company also promotes a seven-day trial framed as "try now, pay later", so you can evaluate draft quality in your own workflow before subscribing.

**Pricing & Plans:** Free tier with limited power (reply and rephrase on all supported sites); Premium at $7.50/month billed monthly with customization, full power, and support; custom Teams plan billed annually with admin controls and 7/7 support. A 7-day free trial is advertised.

- **Reply with AI on any website:** Select any message, comment, or email on a web page and let 1Stroke generate a ready-to-send reply that fits the surrounding conversation.
- **Rephrase and refine with AI:** Rewrite a draft to change wording, shorten it, or shift the tone without leaving the page you are working in.
- **Context-aware, tone-matching drafts:** 1Stroke reads the surrounding context so suggestions match the message thread instead of producing generic templates.
- **Free tier plus Premium upgrade:** The free tier covers reply and rephrase on all supported sites with usage limits, while Premium unlocks full power and customization.
- **Teams and admin controls:** Team admins can manage membership, permissions, and onboarding, with 7/7 customer support on the annual plan.

**Strengths:** Works on any website from the page itself, avoiding copy-paste into a separate chatbot; Two focused jobs — reply and rephrase — that cover most day-to-day writing needs; Free tier is genuinely usable for light reply and rephrase work; Clear, publicly listed pricing with a low-cost $7.50/month Premium tier

**Limitations:** Premium tier is a recurring subscription and the free tier caps usage ("limited power"); Draft quality still needs a quick human review before sending in sensitive contexts; Requires installing a browser extension, so it does not cover mobile app or desktop-app chats; Customization options are simpler than some dedicated brand-voice writing suites

## 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.
