## 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.

## PostPlanify

PostPlanify concentrates on the agency workflow rather than single-brand publishing. Each client sits in its own workspace with its own social profiles, team members, approvals and reports, and the pricing is structured by number of workspaces rather than by seat — every plan includes unlimited users. Publishing runs through official platform APIs for Instagram, X, Facebook, LinkedIn, YouTube, TikTok, Threads, Pinterest, Bluesky and Google Business Profile, so a post can be prepared once and pushed to every relevant network.

The feature set covers the whole content lifecycle: a drag-and-drop calendar for planning and rescheduling, bulk scheduling, a shared Canva-, Drive- and Dropbox-connected media library, an approvals flow with comments and mentions, an inbox that collects comments, DMs and reviews with assignment and DM automations, and analytics with historical trends and best-time-to-post suggestions. AI help is wired in for captions, replies, image generation and rewriting, and PostPlanify states it works with assistants such as ChatGPT and Claude. Reporting produces branded PDFs with the agency's logo and colours that can be downloaded, shared by link, or delivered automatically on a weekly or monthly schedule. There is also a per-workspace link-in-bio page with click tracking and an API plus MCP access for teams that want to connect their own tooling.

Pricing is per workspace with unlimited seats, split into Growth (about $79/month for 15 social profiles), Premium (about $159/month for 30 profiles, adding approvals, advanced analytics, scheduled reports and DM automations) and Scale (about $319/month for 80 profiles, adding full white label and priority support). Annual billing saves roughly 20%, and every plan starts with a free 14-day trial.

**Pricing & Plans:** Paid subscription billed per workspace with unlimited users on every plan. Growth is around $79/month (15 social profiles), Premium around $159/month (30 profiles) and Scale around $319/month (80 profiles); annual billing saves about 20% and a free 14-day trial is available.

- **Multi-client workspaces with unlimited users:** Give every client its own workspace, profiles and team, and invite as many collaborators or client reviewers as you need at no extra seat cost.
- **Calendar, bulk scheduling and approvals:** Plan posts on a drag-and-drop calendar, queue them in bulk, and route drafts through comment-and-mention approval flows before they publish.
- **Unified social inbox:** Collect comments, DMs and reviews from all connected networks in one queue, then reply, label, assign to teammates and trigger DM automations.
- **Analytics and white-label reports:** Track performance, engagement and growth across 10 platforms, and send branded PDF reports that can be delivered automatically each week or month.
- **AI assistant and media library:** Generate captions, replies, images and rewrites with AI, and keep brand assets organised in a shared library with Canva, Drive and Dropbox imports.

**Strengths:** Unlimited users on every plan, so scaling the team never increases the bill; Workspace-based pricing that stays predictable as client count grows; Covers the full agency loop: planning, approvals, inbox, analytics and reporting; Publishes through official platform APIs to 10 networks, with API and MCP access

**Limitations:** Pricing is aimed at agencies, so solo creators may find the smallest plan expensive; There is no permanent free tier — access starts with a 14-day trial; Advanced features such as approvals and white label are split across higher tiers
