Online Office Editors — Documents, Spreadsheets, Presentations

A Full Office Suite, In Your Browser, On European Infrastructure

Most teams reach for Google Docs or Microsoft 365 the moment they need to write a document, build a spreadsheet, or put together a deck. Both work well — and both mean your organisation’s documents live on US infrastructure, governed by US law, tied to an account ecosystem you don’t control.

Mandraki includes a complete office suite — documents, spreadsheets, and presentations — built into the same platform as your mail, files, calls, and tasks. Everything runs on European infrastructure, with no dependency on Microsoft or Google accounts.

Real Word, Excel, and PowerPoint Files

Mandraki does not invent its own document format. You work directly with the open Office formats the rest of the world uses:

• Documents open and save as .docx
• Spreadsheets open and save as .xlsx
• Presentations open and save as .pptx

Open a file a colleague sent from Word, edit it in your browser, and send it back — formatting, tables, formulas, charts, and styling preserved. No conversion step, no “this document was created in a different application” warnings, no fidelity loss on round-trip.

Built for Real-Time Collaboration

Several people can work in the same document at once. Edits appear live, cursors are visible, and there is no “someone else is editing this file” lock. The underlying sync uses conflict-free replicated data types (CRDTs), so concurrent edits merge cleanly rather than overwriting each other.

• Live co-editing across documents, spreadsheets, and presentations
• Comments and replies anchored to the exact text, cell, or slide
• Version history so you can see what changed and roll back
• Templates for documents your team produces repeatedly

Edit Offline — Changes Merge on Reconnect

Connectivity is not always guaranteed — a train, a flight, a venue with poor Wi-Fi. Mandraki’s editors keep working offline. Your changes are stored locally and merge automatically with everyone else’s the moment you reconnect, with no manual conflict resolution.

One Platform, Not Five Tools

Because the editors live inside Mandraki, a spreadsheet is one click from the file that references it, the chat where it’s being discussed, and the task it’s blocking. Documents are stored in your Drive, shared with the same permission model as everything else, and attached to mail, tasks, and calendar events without leaving the platform.

Sovereign by Design

Every document, every keystroke, every revision stays on EU-hosted infrastructure. There is no US account behind the editor, no telemetry leaving the continent, and no third-party processor in the path. For organisations that have moved their meetings and mail off US platforms, the office suite is the last piece — and Mandraki closes the gap.
