Everything your team knows from Google Docs. Without Google knowing your documents.¶

Documents, spreadsheets, presentations and PDFs – together in real time, in the browser or as an app on your computer. Your files stay with you, and they stay what they are: .docx, .xlsx, .pptx.

Documents · .docx · light and dark

Word in the browser. Without Word.¶

Write letters, quotes and contracts the way you know: styles, tables, headers and footers, a table of contents, spell checking. Mail merge and PDF export included. Light or dark, as you like it.

Together

Three people in one document. At the same time.¶

Everyone sees the others' cursors, comments arrive live, changes can be tracked and accepted. No more "quote_final_v3_really_final.docx".

Spreadsheets · .xlsx

Excel sheets that stay Excel sheets¶

Formulas, number formats, filters, charts, pivot tables and conditional formatting. The file stays a real .xlsx – your accountant opens it in Excel as always.

Presentations · .pptx

The presentation for the customer meeting¶

Slides, layouts, themes and transitions, speaker notes and a slide show straight from the browser. PowerPoint files stay PowerPoint files.

PDF

Fill in, sign and redact PDFs¶

Fill in and sign forms, highlight and comment, insert and remove pages, black out what's confidential. Scanned letters become searchable with text recognition.

Notes · .md, .txt

Notes that are simply notes¶

Markdown with a live preview, checklists and tables – for minutes, to-dos and project notes. The file stays text, byte for byte.

Files

All your files in one place¶

Folders, uploads, recently opened, trash. Every saved version can be brought back – even last week's, before someone deleted half the contract.

My files: folders, Word, Excel, PDF, Markdown and PowerPoint files

Sharing

With colleagues or by link to the outside, to edit or only to view, with an expiry date if you like. Guests create an account with one click – no installation, no Microsoft account. No more attachment ping-pong.

New

A new document in three seconds¶

New, type a name, go. Word, Excel, PowerPoint or a note – right in the right folder.

And why all of it is better off with you¶

🇪🇺 Your files stay with you

On your server, or with the desktop app on your own computer. No US cloud, no telemetry. GDPR without the headache.

📄 Real Office files

A .docx stays a .docx. Word, Excel and LibreOffice open everything as before – no format of its own, no lock-in.

💶 No cost per head

No subscription per user. The whole team works along, however big it gets.

🧾 E-invoices

ZUGFeRD invoices straight from the invoice document; e-invoices inside PDFs are read and shown.

🖥️ Also as a desktop app

For Windows, macOS and Linux – with the files in your own Documents folder, no server at all.

🤖 AI, if you want it

Claude and other assistants find, read and write your files with your rights. Changes to an open document need your approval.

✉️ Goes with Kontext

Together with Kontext, your documents sit next to mail, calendar and chat – with one sign-in.

🔓 Open Source

Open source code, built on the European Euro-Office engine.
