## 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.

## TextSight

Most AI-detector sites stop at a percentage. TextSight is built as a workflow instead: you detect, you fix the flagged sentences with the built-in humanizer, and you re-run the check in the same tab to see whether the score actually improved. That loop is the core of the product, and it is why detection and rewriting live under one roof rather than in two separate subscriptions.

Under the hood there is a multi-model detector trained on output from ChatGPT, Claude, Gemini, Llama and Mistral, a 0–100 Humanization Score, and a rewrite engine that only touches the passages you flag. Around that core sit roughly twenty smaller writing utilities — grammar, readability, paraphrasing, summarisation, translation — plus a Chrome extension and add-ons for Word and Google Docs.

TextSight is unusually forthcoming about the limits of detection. It published a benchmark of 1,180 human-written academic papers from 2018, before GPT-3 existed, and reports a 5.85% false-positive rate on that corpus, with the dataset, analysis script and methodology downloadable. The company explicitly labels this its own testing rather than independent third-party validation, and tells educators to treat any score as one signal rather than proof.

**Pricing & Plans:** Freemium. The free tier gives 3 actions a day (around 1,000 words per scan without an account, ~1,500 with one; 260 words per humanization) using the same detector as paid plans. Starter is $9.99/mo, Pro $19.99/mo, Business $39.99/mo and Enterprise $79.99/mo, with annual billing discounting roughly 63%. Lower tiers include 20 daily actions and 40,000 humanizer words a month; Pro adds file upload and 5,000 API calls; higher tiers add team seats, bulk scanning, SSO and more API volume. No card is required to start, and plans can be changed or cancelled from settings.

- **Sentence-level AI detection:** Every sentence gets its own AI confidence score and colour code inside your text, so you can see which lines to fix instead of reacting to one blunt overall verdict. Sentence-level detail starts on the Starter plan.
- **Humanization Score:** A 0–100 score that rises as your writing becomes more natural, recomputed on every scan so you can watch the number move as you edit.
- **Targeted AI humanizer:** The humanizer rewrites only the passages that read as AI-written, keeping your meaning and tone. Free accounts get around 260 words per rewrite; paid plans add thousands of words a month plus Advanced, Business and Casual modes.
- **Detect, humanize, recheck in one place:** Detection, rewriting and re-scoring happen in one window. After a humanize pass you recheck the same text and compare the before-and-after AI percentage side by side.
- **Writing toolset and integrations:** About 20 supporting tools cover grammar, readability, paraphrasing, summarisation and translation, with a Chrome extension for right-click scanning of any text in your browser and add-ons for Word and Google Docs.

**Strengths:** Detection, humanizing and rechecking all happen in one window with no copy-paste between tabs; The free tier runs the same detector as the paid plans, so accuracy is not paywalled; Sentence-level flags point at specific lines rather than giving a single opaque score; The company publishes its own false-positive benchmark, dataset and methodology

**Limitations:** \"Humanization Score\" and AI probability are its own detector's numbers, so they are not an independent verdict; Heavy users (bulk files, folder libraries, team seats) must move to mid or top tiers; Detector accuracy is calibrated mainly on English text; other languages are weaker; False-positive testing is self-run and the vendor explicitly says it is not third-party validation
