## Backgrounder

Backgrounder positions itself as a practical fraud-checking assistant for everyday people and small teams. You paste whatever looks suspicious — an unexpected text about a held parcel, a link in an email, a job offer, a phone number — and Carmen returns a risk level along with the concrete red flags it found, such as a lookalike domain registered days ago, a payment request that no real company makes, or urgency pressure tactics. The service cross-references signals like domain age, blocklist data, and sender authenticity rather than relying on a single heuristic.

The product extends beyond the paste-in checker through three companion surfaces: Carmen Monitor watches pages in the browser and flags lookalike sites before you enter credentials, Carmen Email reviews inbound messages for fake invoices and changed bank details, and Carmen Guardian screens texts from unknown senders. Backgrounder is explicit that these layers sit behind existing email and endpoint security rather than replacing them, and it notes that when money has already moved a human takes over the case.

Pricing is transparent: five free checks a month on the website, $5.99 a month for an individual to add Monitor, Email, and Guardian, $9.99 per seat for small businesses, and API-based enterprise and partner tiers. The company also publishes cited public fraud-loss statistics from the FTC and FBI instead of its own estimates, which is a somewhat unusual transparency signal for this category.

**Pricing & Plans:** Free tier with five checks per month on the website. Personal plan at $5.99/month adds Carmen Monitor, Carmen Email, and Carmen Guardian. Small business at $9.99 per seat covers email, browser, and phone for every seat. Enterprise and partner/MSP options are available via the same API.

- **Ask Carmen anywhere:** Paste a text, email, link, phone number, screenshot, or company name and get a risk verdict with the specific red flags and recommended action in under a minute.
- **Carmen Monitor for the browser:** Checks pages as you browse and warns about lookalike or freshly registered domains before you type a password, with on-device redaction of personal data.
- **Carmen Email for the inbox:** Reviews inbound mail for fake invoices, changed bank details, and executive impersonation, holding suspicious messages for review with the reason attached.
- **Carmen Guardian for SMS:** Screens texts from unknown senders, including ones your phone filtered, and evaluates links and payment requests typical of parcel and bank scams.
- **Human follow-up on losses:** When a scam has already cost money, the case is escalated to a person for guidance on reporting and recovery steps.

**Strengths:** Explains the reasoning behind each verdict rather than giving a bare score; Covers browser, email, and SMS in addition to a paste-in checker; Transparent published pricing with a genuinely useful free tier; Uses cited third-party fraud statistics instead of self-reported numbers

**Limitations:** Phone protection (Carmen Guardian) was still listed as coming soon; The free allowance of five checks per month is small for heavy users; Accuracy still depends on external data sources such as domain registries and blocklists

## 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.
