## 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.

## OpenBuckets

OpenBuckets is a search-oriented security platform centred on one common cloud misconfiguration: storage buckets that are accidentally left publicly readable. Instead of requiring you to guess bucket names one at a time, it lets you search across publicly reachable cloud storage and see what is exposed. Results can be narrowed by file type, which makes it practical to spot whether a bucket is leaking documents, database dumps, backups or media rather than assuming exposure from a name alone.

The intended audience is the security community — penetration testers, bug-bounty hunters, red and blue teams, and organisations auditing their own cloud posture. For a defensive team, the value is continuity: knowing which of your own buckets are reachable from the open internet is the first step in locking them down. For offensive or research work, it is a fast way to triage candidate targets before deciding what deserves a report.

Because the platform is aimed at professional security work, access and pricing are arranged by contacting the OpenBuckets team rather than through a self-serve checkout. Responsible use is expected: querying third-party buckets should stay within authorised testing scopes, and exposed data should be routed to the owner through proper disclosure channels rather than downloaded or exploited. The site presents the search as the entry point to a broader cloud-storage exposure workflow.

**Pricing & Plans:** Paid, contact for pricing — the website search is the entry point and plans are arranged directly with the OpenBuckets team.

- **Open bucket search:** Query exposed buckets by name, keyword or provider and see which ones return publicly readable results.
- **File-type targeting:** Narrow results by file extension so you can assess whether sensitive document, database or media files are publicly reachable.
- **Endpoint visibility:** Surfaces the storage endpoints behind each match, making it easier to verify exposure and route a disclosure to the right owner.
- **Security-research focus:** Built for security research workflows — quickly triage public exposure without touching the underlying data irresponsibly.
- **Continuous exposure monitoring:** The platform is positioned for teams that need ongoing visibility into their own cloud storage footprint, not just one-off checks.

**Strengths:** Focuses on a real, high-impact cloud misconfiguration rather than generic scanning; File-type filtering makes exposure assessment faster; Useful for both defensive audits and authorised offensive testing; Simple web interface with no local setup

**Limitations:** Pricing is contact-based, so costs are not transparent upfront; Searching for exposed buckets must only be used for authorised security work; Empty buckets may serve no results if no open buckets exist for a given query; Free search is limited; deeper file-type filtering and bulk work require engagement
