## Dechecker

Dechecker centers on a paste-and-check workflow: you drop in up to roughly 1,000 words, or upload a document, and the detector returns an overall AI probability plus a sentence-level breakdown showing which passages triggered the model. Alongside the core check you can stack optional passes such as a plagiarism scan, a grammar pass and a fact-check, and the platform also exposes sibling tools for AI code detection, AI image detection, transcription, summarization and essay writing.

Its stated positioning is accuracy with few false positives, achieved by scoring sentence structure, phrasing rhythm and transitions rather than looking for fixed keyword lists. When something is flagged, the tool explains why that sentence reads as machine-generated and offers one-click rewriting so writers can smooth the pattern out instead of rewriting from scratch. Bulk document upload, downloadable reports and a saved history are provided for people checking more than one file.

Accessibility is the main selling point: the checker is free, needs no account for a basic run, and shows a "100 free credits" offer alongside paid options for heavier usage. Text is described as processed without being stored, which matters for students and professionals checking unpublished coursework or client material. The site is translated into several languages and claims more than a million users.

**Pricing & Plans:** Dechecker advertises a free tier with no registration required for basic AI checks, and the site surfaces a "claim your 100 credits" offer for signed-in users. Beyond that, plan details and paid tiers vary, so check the pricing page for current limits and per-word or per-credit bundles.

- **Sentence-level AI detection:** The checker returns an overall AI probability plus a per-sentence breakdown, so you can see exactly which lines read as machine-written instead of guessing from a single number.
- **Built-in humanizing rewrites:** Flagged sentences come with an explanation of what triggered the flag and one-click rewrite suggestions that reduce tell-tale AI patterns while keeping your meaning.
- **Add-on verification passes:** Optional plagiarism, grammar and fact-check modules can be layered onto the same text, turning a single submission into a broader originality and quality review.
- **Document upload and bulk scanning:** Paste text directly or upload files, and scan multiple documents in one pass when you are reviewing a stack of papers or drafts.
- **Report history and downloads:** Detection results are saved to a library and can be exported, which helps when you need a record of checks over time or proof of a review.
- **Extra detectors for code and images:** Separate tools detect AI-written code and AI-generated images, covering project types beyond plain essays and articles.

**Strengths:** Core AI check is free and requires no signup for a quick run; Sentence-level explanations make results actionable rather than just a score; Extra plagiarism, grammar and fact-check modules cover more ground in one place; Document upload, bulk scanning and saved reports suit multi-file workflows

**Limitations:** The free allowance is credit and word limited, so heavy use runs into paid tiers; AI detectors in general can still misfire on heavily edited or non-native human writing; Detection accuracy depends on language and text length, so very short passages are less reliable

## 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.
