In their own words
NeuralWriter
NeuralWriter is a set of writing, image, and text-analysis tools available on the web, through a Chrome extension, and by API. Its writing tools cover paraphrasing, prompt generation, translation, summarization, word counting, and headline generation. The paraphraser has Light, Medium, and Hard modes and accepts up to 10,000 characters; its API page lists 30 supported languages. The prompt generator creates prompts for ChatGPT and GPT models with the same character limit and language count. Summarization accepts up to 10,000 characters and allows output from 20% to 90% of the source. The word counter accepts up to 25,000 characters and reports readability measures. An AI detector compares five engines, highlights sentences, and gives a consensus verdict without sign-up. Image tools include generation and upscaling, with listed resolutions through 8K and 4K respectively. The free online tools plan costs nothing.
StealthWriter
StealthWriter rewrites AI-generated or AI-assisted text to improve phrasing, flow, and clarity, and includes an AI detector. Its humanizer provides light, medium, and aggressive rewrite levels. The detector estimates whether submitted text may be flagged as AI-generated and gives overall and sentence-level feedback. It accepts text from tools such as ChatGPT, Claude, Gemini, Llama, Mistral, Copilot, and Jasper; listed supported languages include Spanish, French, German, Italian, Portuguese, and Dutch. StealthWriter runs in modern browsers on desktop, tablet, and mobile, with Android, iOS, and web listed as platforms. The free plan allows 10 humanizations and 10 AI scans daily, up to 1,000 words per input, and includes Ghost 5.2 Mini. Paid plans start at $20 a month and allow up to 5,000 words per input, with Ghost 5.2 Pro and Ghost Legacy also included. The public detector demo has a 500-word scan limit and daily limits. The maker advises reviewing rewritten text because a rewrite can alter details or how a claim is expressed.
