EdenText is a web-based, powerful word processor for everything from quick notes to full-length books. No server, no account — processing runs locally and your documents never leave your computer. Just one URL away, or completely offline as a slim browser app — under 2 MB on first load¹. The interface comes in English and German.

Note

EdenText is young, in beta and actively developed — more features are on the way. It is tested — the full suite plus LibreOffice round-trip checks run on every commit — but expect occasional bugs, and keep backups of documents you care about. The browser copy also keeps the last three versions of the open document, and offers them if it ever fails to load one. What is still missing is listed under Not yet implemented and Known limitations.

Features

• Real page layout — A4/Letter pages, margins, headers & footers, footnotes, columns, page and line numbering, watermarks; mirrored margins and chapters opening on a right-hand page for books
• Opens and saves .odt and .docx, exports PDF; templates (.ott/.dotx) and a letter gallery (DIN 5008); password-protected files in both formats
• Plays well with Word and LibreOffice — documents keep their layout across all three, backed by a sophisticated test pipeline
• Styles — paragraph, character, table and list styles with inheritance, chapter numbering
• Tables with styles, sorting and spreadsheet-style formulas
• Everything a thesis needs — table of contents, captions, cross-references, citations & bibliography, alphabetical index, formulas (LaTeX)
• Review tools — track changes and threaded comments with margin balloons, printable markup, spell check (English & German), grammar check (English), synonyms
• Private by design — your documents never leave your computer, all processing runs locally; works offline as an installable app. The site counts anonymous visits (GoatCounter, EU-hosted, no cookies); the editor sends nothing
• Any current browser — in Chrome and Edge, Save writes back to the opened file; other browsers receive each save as a download, so turn on "Always ask where to save" in their settings to pick the location

Gallery

The documents behind these pictures are in docs/showcase/ as .odt and .docx, ready to open in EdenText, LibreOffice or Word. They are built by scripts/showcase/run.mjs; the photographs are NASA's and the book is Lewis Carroll's, both public domain.

Review — tracked changes, threaded comments in the margin, a draft watermark	Book — A5, mirrored margins, chapters opening on a right-hand page, running heads; the numbering restarts after the front matter, so page 11 prints the folio 9
Newsletter — columns, pictures with captions, a sidebar box	Tables — table styles and spreadsheet-style formulas

1. Over the wire, compressed: ~0.4 MB of app code, the rest the bundled fonts a page shows and the spell checker with its dictionary. Further fonts, the second dictionary and the thesaurus load on demand; the complete offline install is ~25 MB, or ~33 MB with the English grammar check switched on. ↩︎
