## 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 Text is described as processed without being stored, which matters for students and professionals checking unpublished coursework or client material.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

## Originality.ai

Originality.ai was built for the era in which a meaningful share of published text is machine-generated. Its core AI Checker classifies text as AI, human or mixed and highlights the individual sentences driving the verdict, while the same scan can also surface plagiarism matches, readability grades, grammar issues and shaky factual claims. Publishers, SEO teams, agencies and educators use it to vet freelancer drafts, student submissions and high-volume content pipelines before anything goes live.

The platform scales from a free trial scan up to enterprise workflows. A bulk scanner handles many documents at once, while the API and MCP integration let developers embed detection directly into their own tools. A Chrome extension runs checks inside Google Docs and the web, and a Writing Replay feature records the typing process so authors can demonstrate authorship. Team management, shareable reports, PDF exports and configurable scan history round out the publishing workflow.

**Pricing & Plans:** Free tier with a one-time 10K-word (100 credit) allowance and no subscription. Pro is about $14.95/month monthly or $12.95/month billed yearly for 200K words per month, and Enterprise is about $179/month monthly or $136.58/month yearly for 1.5M words per month. Additional credits can be purchased; 1 credit equals 100 words.

- **AI detection with sentence highlights:** Classifies text as AI, original or mixed and pinpoints which sentences most influenced the score, so reviewers know exactly where to look.
- **Plagiarism and content-quality checks in one pass:** Runs plagiarism matching, readability scoring, grammar and spelling fixes, guideline checks and fact/hallucination screening from the same scan.
- **Bulk scan, files and full-site scanning:** Upload DOCX, PDF or DOC files, paste text, scan a URL, or queue large batches of documents to process at scale.
- **Extensions, API and MCP integration:** Check content inside Chrome and Google Docs, or wire detection into your own apps through the REST API and MCP server.
- **Writing Replay and shareable reports:** Replay how a document was typed, tag scans, and export shareable links or PDF reports for teammates, clients or review boards.

**Strengths:** Single scan returns AI, plagiarism, readability, grammar and fact checks together; Sentence-level highlights and Writing Replay make results easy to defend; Bulk scan, API, extensions and team roles suit agencies and enterprises; Free trial credits let you test accuracy before paying

**Limitations:** Credit-based pricing can add up for very high-volume publishing; AI detectors can never be 100% certain, so results should be treated as signals rather than proof
