Dusk Office is an online office suite with Drive, Docs, Sheets, Slides, Forms, Calendar, Mail, Chat, Meet, Notes and Sites, all under one sign-in. Edit together in real time, and open and save Word, Excel and PowerPoint files.



Docs, Sheets, Slides and Sites show other people's edits as they type, with live cursors in Sheets and automatic merging when two people edit the same document.
Import and export .docx, .xlsx and .pptx, including tables, images, formulas, number formats, merged cells, headers, footers and page numbers.
Over 170 functions including XLOOKUP, FILTER, SORT, UNIQUE, LAMBDA and dynamic arrays, plus pivot tables, charts, filter views, validation, conditional formatting and protected ranges.
Very large sheets are stored on the server, uploads resume if interrupted, and sorting, filtering, finding and recalculating run there as background jobs.
Dusk Mail receives and sends DKIM-signed mail, with threads, labels, filters, aliases, spam filtering and shared team addresses such as support@.
Dusk Script runs in a sandbox in every editor to automate sheets, docs, slides, forms and Drive, on form submit, on edit or on a schedule, and adds custom spreadsheet functions.
Runs on: Any modern browser at duskoffice.com, and every app installs on phones and desktops with offline support.
