Nothing is saved or tracked on external servers.</li> <li> <strong>100% Free &amp; Ad-Free:</strong> No paywalls, no intrusive ads, and no mandatory registration.</li> <li> <strong>Runs Everywhere (PWA):</strong> Works smoothly on Windows, Linux, Mac, tablets, and phones directly from the browser, with PWA support.</li> </ul> <h3> 📦 What is Included in OfficeClone? </h3> <p>Instead of separate tools, OfficeClone unifies 6 core productivity apps in one clean hub:</p> <ol> <li> <strong>WordClone:</strong> Rich-text document editor with real A4 pagination, formatting ribbons, official DOCX import/export, and AI contract drafting.</li> <li> <strong>ExcelClone:</strong> Spreadsheet editor with real-time formulas, charts, CSV/XLSX support, and AI formula generation in English and Portuguese.</li> <li> <strong>PointClone:</strong> Slide creator with modern layouts, speaker notes, and AI-powered pitch deck generation.</li> <li> <strong>ProjectClone:</strong> Complete project manager featuring interactive Gantt charts, WBS task breakdown, and critical path tracking (MS Project style).</li> <li> <strong>FreePDF:</strong> Fast client-side PDF toolkit to merge, split, compress, and interact with PDF files.</li> <li> <strong>KeepAi:</strong> Smart note-taking scratchpad with contextual AI research and organization.</li> </ol> <h3> 🌟 Recently Featured on AlternativeTo </h3> <p>OfficeClone was recently reviewed and listed on <strong><a href="https://alternativeto.net/software/officeclone/about/" rel="noopener noreferrer">AlternativeTo</a></strong> as a recommended free alternative to Microsoft 365 and Google Workspace.</p> <h3> 🚀 Try It Live </h3> <p>You can test the entire suite right now without creating an account:<br> 👉 <strong>Live Web App:</strong> <a href="https://4u.ia.br/app/office/" rel="noopener noreferrer">https://4u.ia.br/app/office/</a><br><br> ⭐ <strong>GitHub Profile:</strong> <a href="https://github.com/4u-Labs" rel="noopener noreferrer">https://github.com/4u-Labs</a></p> <p>I would love to hear your feedback, thoughts, or suggestions in the comments below!</p> ai privacy showdev webdev
