## 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.

## SendBridge

SendBridge is an email verification service built around one job: keeping your mailing lists free of addresses that will bounce, complain or trigger spam traps. Rather than a simple valid/invalid check, every address is categorized as Deliverable, Undeliverable, Risky or Unknown, which lets you decide whether to send, suppress or throttle a contact. The risky category is the interesting one, covering spam traps, role-based accounts, catch-all domains and disposable addresses that a naive checker would let through.

The workflow is designed to be non-technical. You create a free account, upload a list into the client area, and download the cleaned results as XLSX, CSV or TXT in the same order as your upload, ready to push into your sending platform. For teams that need verification at the point of capture, a real-time API with examples for Go, Java, PHP, Python and .NET lets you check addresses during signup or import.

SendBridge also bundles a set of free deliverability tools, including a Mail-Tester alternative that scores your sending setup out of 100 with SPF, DKIM, DMARC, rDNS and 23+ blacklist checks, plus an email validator, SPF record generator and DNS/MX lookup tools. The service is operated by CORE LABS s.r.o. in Prague, and free accounts include 100 verifications a month.

**Pricing & Plans:** Freemium. Free account includes 100 email verifications per month, plus free deliverability and DNS tools with no daily cap. Paid plans and higher-volume verification are available; check the pricing page for current tiers.

- **Deliverability Classification:** Every address is classified as Deliverable, Undeliverable, Risky or Unknown, so you know exactly why a contact should be kept, throttled or dropped.
- **Risk and Spam-Trap Detection:** Detects the address types that quietly wreck campaigns, including spam traps, role accounts, catch-all domains and disposable inboxes.
- **Bulk List Cleaning:** Upload a list in the client area and download a cleaned file in Excel XLSX, CSV or TXT while keeping your original row order.
- **Real-Time Verification API:** Verify addresses in real time on signup or import with documented examples for Go, Java, PHP, Python and .NET.
- **Free Deliverability and DNS Tools:** A free Mail-Tester style deliverability checker scores your sending setup out of 100 with SPF, DKIM, DMARC, rDNS and 23+ blacklist checks, with no daily cap.

**Strengths:** Free tier with 100 verifications per month to test accuracy; Four-way classification (Deliverable, Undeliverable, Risky, Unknown) gives actionable results; Real-time API with examples for Go, Java, PHP, Python and .NET; Free Mail-Tester alternative with unlimited tests and no account required

**Limitations:** Full pricing tiers are not shown until checkout, so larger volumes require contacting the team or pricing page; Catch-all and role-based addresses still add uncertainty even with high claimed accuracy; No native integrations ecosystem highlighted beyond the API
