Office Max in depth

Office Max

Documents, spreadsheets and slide decks in one offline-first desktop app.

A rich-text document editor with a structured citation registry, deterministic numbering and a bibliography you can refresh.
A spreadsheet formula engine running in the app, with 103 user-facing functions, A1 ranges and dependency recalculation that detects circular references.
A slide editor with a Present mode.
DOCX and XLSX import with a review step. Before a copy is made, the app shows what will be lost and what is supported. The original file is kept unchanged and is verified by checksum.
DOCX and XLSX export of the supported subset, plus local drafts and autosave.
A signed offline licence lease, so you can keep working without a connection.

Limits: Imports cover a supported subset; Word citation fields and syncing with external reference managers are not claimed. Import reports are local checksums, not a guarantee of full fidelity.

How it works

It is a separate desktop product on Culltron's shared, hardened platform, with its own full editor and local workspace.
A local, authenticated runtime serves the editor. Your files stay on your machine.
A signed licence lease unlocks the paid edition, and Ultra X27 features are enforced by the server, not just hidden.
Changes write new copies, usually with checksum receipts, so originals are not overwritten.
