ElixirOffice gives teams a Word, Excel, and PowerPoint style editing suite that runs in the browser on a server you control. The ribbon tabs, Alt key tips, mini toolbar, and keyboard shortcuts match Microsoft Office, so muscle memory keeps working from the first day. Documents in .docx, .xlsx, .pptx, .odt, .ods, and .odp open with layout tuned to match Word, and free metric-compatible fonts keep page breaks stable. Comments appear in the margin, tracked changes show every edit, and several people can co-edit a file in real time. Connect Nextcloud or Murena Workspace through a revocable app password to browse, open, and save with conflict protection. Spreadsheets bring pivot tables, charts, Flash Fill, and Quick Analysis, and presentations add a slide sorter, sections, and Presenter View. An optional assistant called Ask Elixir can rewrite text, write formulas, build charts and pivot tables, or draft slides with the AI service you choose, including one you host yourself. It stays off until you enable it, and its edits wait for Accept or Discard. Forty-five interface languages and dozens of spelling dictionaries suit schools and international teams. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
