## EchoMark

EchoMark targets the gap that conventional data loss prevention cannot cover. DLP tools monitor content as it crosses the network, but they are blind to information leaving through a phone camera pointed at a screen, a printed handout, or a screenshot pasted into a chat. EchoMark takes the opposite approach: content leaves normally, but every copy carries a hidden, individualized identifier that can be recovered after the fact.

The platform covers four surfaces. Email messages and attachments are marked automatically on send. Documents such as board decks, term sheets and reports are marked and shared through a secure link. Images — designs, artwork, photographs — carry marks built to survive cropping, compression, printing and re-photographing. Screen marking covers everything displayed, across browsers, line-of-business apps, collaboration tools and AI assistants. A developer API applies the same marks programmatically.

The workflow is straightforward: watermark silently on distribution, discover the leaked artifact, then upload it to the investigation tool, which recovers the mark and returns the recipient whose copy leaked, along with a confidence score, creation timestamp and chain-of-custody record. Because marks live in the content rather than file metadata, stripping metadata or converting formats does not remove them. EchoMark offers free signup and demos, with enterprise pricing on request.

**Pricing & Plans:** EchoMark offers a free sign-up and self-serve entry point, plus demos and custom enterprise plans priced on request. Exact figures depend on deployment scope and seats, so they are quoted directly by the sales team.

- **Invisible per-recipient watermarking:** Each recipient's copy of an email, document or image carries a different hidden mark, so a single leaked artifact points to one person.
- **Analog-proof image marks:** The Luma image mark is engineered to survive printouts, photocopies, mobile photos and compression, where metadata-based tagging fails.
- **Screen watermarking:** Marks everything shown on a display, covering any app or file type including browsers, collaboration tools and AI assistants.
- **Leak investigation tool:** Upload a leaked file, screenshot or photo and get back the source recipient with a confidence score and chain-of-custody documentation.
- **API and DLP complement:** A developer API applies marks programmatically, and the platform runs alongside existing DLP rather than replacing it.

**Strengths:** Covers the analog and offline leak paths that DLP structurally cannot see, such as photos of screens and printouts; Marks are embedded in content, not metadata, so they survive re-saving, format conversion and cropping; Provides confidence scores and chain-of-custody evidence suitable for escalation rather than just suspicion

**Limitations:** Effective use requires marking content before distribution, so retroactive investigation of unmarked material is not possible; Enterprise pricing is not published, and deployment in air-gapped or special cloud environments involves a scoping process

## 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.
