## 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.

## Katteb

Katteb has moved beyond prompt-and-answer AI to long-running agents. You state what should be true, for example winning ten new B2B clients this quarter or growing store sales by 20 percent, and pick a horizon of 14, 30, 60, 90, or 180 days. Before planning, the agent searches the web to learn who buys, who decides, what competitors charge, and where your customers spend time, then writes a plan you can edit for free.

The plan contains the outcome, the metric it will move, dated milestones, and up to three repeating workflows that run hourly, daily, weekly, or monthly. Each run opens its own real browser session and works in the accounts you connected, respecting a daily sending limit and never contacting the same person twice. That makes it useful for outreach, lead qualification, content and page rewriting, and campaign optimization.

A daily 8am report summarizes what the agent did, what it learned, any blockers, and what it will do next, with numbers read from your tools such as a CRM rather than guessed. Everything that worked or failed goes into its memory, so later days build on earlier ones. Katteb also exposes chat, task, and agent views for one-off work, and a new capability gives your agent its own phone number.

**Pricing & Plans:** Free to start, with paid plans for ongoing goal-based agent work. Writing a goal plan is free. Exact tier prices are not shown on the homepage, so check the pricing page before committing.

- **Goal-based autonomous agents:** Set an outcome and a deadline of 14 to 180 days, and the agent plans the work and runs it day after day toward the target metric.
- **Market research before planning:** The agent searches the web for buyers, decision-makers, competitor pricing, and channels, citing its sources before it drafts the plan.
- **Repeating workflows:** Plans include up to three workflows that repeat hourly, daily, weekly, or monthly, such as prospecting and follow-ups.
- **Works inside your tools:** Each run opens its own browser and acts in the accounts you connected, with daily send limits and duplicate contact protection.
- **Daily reports and memory:** An 8am report shows what was done, what was learned, blockers, and next steps, with numbers read from your tools and remembered over time.

**Strengths:** Goals, plans, milestones, and workflows in one place; Research and planning happen before the agent starts acting; Reports numbers read from your tools instead of estimates; Free to write a goal plan before committing

**Limitations:** Exact plan pricing is not shown on the homepage; Long-running agent work is best suited to connected accounts and tools; Autonomous outreach still needs daily human review
