Ludwig Rewrite uses advanced AI language models to analyze your text and generate multiple alternative versions. For each rewrite, the AI considers your selected tone (formal, neutral, casual), maintains your core meaning, and provides explanations of what changed and why. You get instant access to several options and can choose the one that best fits your needs.

Most paraphrasers give you one AI suggestion with no alternatives. Ludwig provides multiple rewriting options for every text, each with clear explanations of what changed. You can compare versions side-by-side and choose the one that best matches your intended meaning and tone—instead of accepting a single AI output without options.

Yes. Select from formal, neutral, or casual tones before rewriting. The AI adapts vocabulary, sentence structure, and style to match your chosen register—whether you're writing an academic paper, business email, or casual blog post.

ChatGPT and Claude can rewrite text, but they typically give you one version at a time. Ludwig Rewrite provides multiple alternatives instantly, optimized for your chosen tone and purpose. You can compare options side-by-side, see explanations for each change, and select the best version—rather than generating rewrites one by one in a chat interface.

Free users can rewrite up to 500 characters per query. Premium users get up to 2,000 characters per rewrite—perfect for full paragraphs or longer sections. For documents longer than 2,000 characters, use Ludwig Editor which handles complete papers and reports.

Ludwig Rewrite helps you express ideas in your own words while maintaining your original meaning. However, it's not primarily a plagiarism avoidance tool—it's a writing improvement tool. If you're paraphrasing source material, you should still cite your sources appropriately. Use our AI Detector to verify your text doesn't resemble AI-generated content.

Absolutely. Many PhD students and researchers use Ludwig Rewrite to improve clarity while maintaining academic tone. The formality controls help you maintain appropriate register for scholarly writing, and having multiple rewriting options lets you choose the version that best expresses complex academic concepts.

Install the Ludwig Desktop App and use keyboard shortcuts to rewrite text from any application—Word, Google Docs, email clients, or web browsers. No need to copy-paste into a separate tool. Select your text, press the shortcut, choose your preferred rewrite option, and it replaces the original directly in your document.

Yes. Ludwig follows European data protection standards with servers in Italy, Germany, and France. Your texts are processed to provide rewrites but are never stored permanently, sold to third parties, or used for advertising. We maintain strict data sovereignty and privacy for all users.

You can input text in 100+ languages and receive English rewrites with multiple phrasing options. This is particularly useful for non-native English speakers who want natural, professional English output—not just literal translations from generic tools.
