What it is

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.
