In their own words
NEURONwriter
NEURONwriter uses AI to help create content and improve SEO, with a web app and Chrome extension. Its Content Designer generates articles with titles, descriptions, and headings using NLP and AI. NLP Terms suggests words and phrases based on top-ranking Google competitors. Internal-link insertion uses Google Search Console data and AI to select anchor text and target pages. A plagiarism checker compares text with other sources to analyze originality. The browser extension provides writing recommendations in Google Docs, WordPress, and Shopify. Listed integrations include WordPress, Google Search Console, Chrome Extension, Zapier, Boost.space, and an API; WordPress, Google Search Console, and API features are available from Gold upward. Users can connect their own OpenAI or Anthropic API keys for content generation. Every plan includes AI Visibility Standard, with monitored-question allowances that vary by subscription. A free plan and 7-day trial are listed. Yearly plans range from $19 a year for Bronze to $97 a year for Diamond. The maker describes its audience as businesses and content creators seeking content that performs in search rankings.
Originality.ai
Originality.ai provides tools for checking AI-generated text, plagiarism, facts, readability, grammar, spelling and content quality. Its free Basic plan costs $0.00 per free and provides three AI scans per day, with up to 2,000 words per scan. The AI detector offers configurable allowances of 0%, 5%, 15%, 25% or 40%. A website scanner can crawl a site, identify pages likely to contain AI-generated content and run scheduled scans. The browser extension scans Google Docs, web pages or selected text, and includes writing replay, typing behavior insights and shareable reports. A REST-based API submits text for AI and plagiarism scans and returns detailed results; the maker says AI detection supports 30 languages. API AI scans require at least 50 words, and the help page says accuracy decreases below 100 words. Originality.ai describes detection results as probabilistic estimates that may produce false positives or false negatives, not conclusive proof. Pro costs $12.95 per month billed yearly, with a monthly option at $14.95 per month. The service is available through web, API and extension.
