Website: https://neuralwriter.com Contact: support@neuralwriter.com Founded: 2022-04-15 ## About NeuralWriter launched on 2022-04-15 as a free AI paraphrasing tool and grew into a platform for rewriting, summarizing, translating, grammar checking, AI-content detection, image editing and file conversion. The paraphraser remains the flagship tool and lives at the site root. The web tools are free and need no account; a free Chrome extension unlocks the Hard paraphrasing strength on desktop. --- ## Paraphrasing Tool URL: https://neuralwriter.com/ A free AI paraphraser that rewrites sentences and paragraphs while keeping the meaning. Unlike synonym spinners, it reads the whole paragraph and rebuilds each sentence, so the result reads naturally. It answers in the language of the input text, whatever the language of the interface. Key facts: - Price: free, no sign-up, no daily limit. - Character limit: 10,000 per run (about 1,500 words). - Interface languages: 30. - Diff view: every replaced word is highlighted, with a rewrite score (reworded share, restructuring, meaning kept, fluency). - Strength: - Light — keeps the sentence structure and refreshes the wording. - Hard — restructures sentences for a more original text; on desktop it needs the free Chrome extension. - Writing styles (8): Standard, Fluent, Formal, Academic, Simple (for readers aged about 11–14), Creative, Shorten (about 30–50% shorter), Expand (about 30–60% longer). - Freeze words ("Don't change"): up to 20 words or phrases (names, brands, terms, SEO keywords) kept exactly as written in every mode. Candidates such as acronyms, CamelCase brand names and quoted phrases are suggested from the text. If a rewrite changes a frozen phrase, the tool retries once. - Keeps names, titles, brands, numbers and technical terms unchanged (no "thesaurus" swaps), and keeps formatting: Markdown and HTML markup, headings, bold text, lists, tables, links, inline code, in-text citations such as (Smith, 2020) or [1] and the reference list, word for word. - Privacy: submitted texts and results are stored for at most 24 hours for troubleshooting, then deleted automatically; they are never published, never added to plagiarism databases and never sold. - Language standards for any language: - ISO 24495-1 plain language — key information first, short active sentences, everyday words. - Easy-to-Read (ISO/IEC 23859, with the Inclusion Europe "Information for all" rules) — one idea per sentence, every hard word explained, one sentence per line. - CEFR A2–B1 — high-frequency vocabulary and sentences of about 8–15 words for language learners. - CDC Clear Communication Index — main message first, numbers explained, everyday words. - ASD-STE100 Simplified Technical English — up to 20 words per instruction and 25 per description, one instruction per sentence, active voice, simple tenses. - Attempto Controlled English — one fact or rule per sentence, explicit nouns, "if… then" and "every" patterns. - UX writing — concise interface copy that addresses the user and says what happens next. - Amazon-style narrative — memo prose with the conclusion first and data instead of adjectives. - Standards for English text only: Oxford 3000, Basic English (Ogden), Globish & VOA Learning English, Academic Word List. For text in other languages these modes are disabled. - National standards, offered when the text is in that language: Federal Plain Language Guidelines (English), Leichte Sprache and Einfache Sprache (German), Lectura Fácil (Spanish), FALC (French), Linguagem Simples (Portuguese), linguaggio chiaro (Italian), taalniveau B1 (Dutch), klarspråk (Swedish), klarsprog (Danish), selkokieli (Finnish), ETR (Polish), snadné čtení (Czech), KÉK (Hungarian), lengvai suprantama kalba (Lithuanian), やさしい日本語 (Japanese), ясный язык (Russian). - Standard modes follow the published rules of each standard and produce a draft. Easy-to-read standards expect a final check by readers from the target group, and quality labels (the Inclusion Europe easy-to-read logo, the Finnish selkotunnus) are awarded only by their own organisations. Use cases: restating sources in your own words, polishing drafts, adjusting tone for business or academic writing, making official texts understandable, preparing easy-to-read drafts, simplifying texts for language learners, writing technical procedures. --- ## Plain language and easy-to-read standards by language - English: Plain Writing Act of 2010 and the US Federal Plain Language Guidelines (written by PLAIN); they influenced ISO 24495-1. - German: DIN 8581-1:2024 Einfache Sprache (applies ISO 24495-1 to German, keeps all information) and DIN SPEC 33429:2025 Leichte Sprache (for people with learning difficulties, keeps only the most important content).

The web tools are free with no sign-up. The Hard paraphrasing strength on desktop needs the free Chrome extension. - **Do I need an account?** No. - **Is there a paid plan?** Only for the Paraphrasing API on RapidAPI, which has a free demo plan. **Paraphrasing** - **Which modes are there?** 8 writing styles, 2 strengths (Light and Hard) and language standards: ISO 24495-1, Easy-to-Read (ISO/IEC 23859), CEFR A2–B1, CDC Clear Communication Index, ASD-STE100, Attempto Controlled English, UX writing, Amazon-style narrative, four English-only word-list standards and 17 national standards for 16 languages. - **Will AI detectors flag paraphrased text?** They might. Paraphrasing changes wording and sentence structure, which often lowers AI-detection scores, but no paraphraser can guarantee that a text passes every detector; Originality.ai, Turnitin and GPTZero use different methods and often disagree. Check the result with the AI Content Detector and follow your institution's rules on AI tools. - **Is paraphrasing legal?** Yes. You restate the meaning in different words instead of copying the text. - **Does paraphrasing count as plagiarism?** Presenting someone else's ideas as your own is plagiarism even in new words; cite the original source. Rewording your own text is normal writing practice. - **Does it keep my language?** Yes. The paraphraser answers in the language of the input text, even when the interface is in another language. **Summarize** - **What's the difference between summarizing and paraphrasing?** Summarizing shortens the text and keeps the key points. Paraphrasing rewrites the full text in different words and keeps the meaning. **AI Content Detector** - **Which detection engines does it use?** Six in parallel: QuillBot, ZeroGPT, Originality.ai, Copyleaks, Grammarly and Ahrefs. - **Are AI detectors accurate?** They are useful signals, not proof. Engines often disagree, so compare several scores and read the highlighted sentences. **Paraphraser: names, formatting, privacy** - **Does the paraphraser change names and technical terms?** No. Proper names, book and product titles, brands, numbers and fixed terms stay unchanged; any other word or phrase can be locked with "Don't change" (up to 20). - **Does it keep formatting, citations and references?** Yes. Markdown and HTML markup, headings, bold text, lists, tables, links and code come back where they were; in-text citations and the reference list stay word for word. - **Do you store the texts?** Only briefly: texts and results are kept for troubleshooting for at most 24 hours, then deleted automatically. They are never published, never added to plagiarism databases and never sold. **Limits** - **What's the character limit?** 10,000 per run for the Paraphraser, Summarizer, AI Detector and Translator; 25,000 for the Word Counter. ## Company - Domain: https://neuralwriter.com - Founded: 2022-04-15 (started as the Paraphrasing Tool). - Support email: support@neuralwriter.com - Browser extension: free Chrome extension; unlocks the Hard paraphrasing strength on desktop. - Legal: [Privacy Policy](https://neuralwriter.com/privacy-policy/), [Cookies Policy](https://neuralwriter.com/cookies-policy/), [Terms of Service](https://neuralwriter.com/terms-of-service/).
