Rutba Office
Seven apps, one installer
They share a shell, a design system and a set of shortcuts, so the second app you open behaves like the first. They also share an engine, which is the part that decides whether a file survives being edited.
Every account, every archive, one inbox
IMAP and SMTP for the accounts you use now, and — the part no other free client does properly — the archives other clients leave behind. Outlook .pst and .ost are read in full: folders, messages, recipients and attachments, out of the node and block B-trees rather than through Outlook.
IMAP · SMTP · .pst · .ost · .olm · mbox · .eml · .emlx · .msg
Documents that open the same everywhere
Word
A word processor on a .docx engine we wrote, not a converter wrapped around someone else’s. Tracked changes, comments, styles, sections and pagination — and a PDF writer with no dependencies underneath the export.
Reads and writes .docx · reads .odt, .rtf, .doc, Markdown, text · exports PDF
Real formulas, real recalculation
Worksheets
A spreadsheet with an actual calculation engine — parser, evaluator and dependency ordering — so a workbook recalculates in the right order rather than showing you the last values it was saved with. Number formats, merged cells, charts and conditional appearance all render.
Reads and writes .xlsx and .csv · reads .ods, .xls, .tsv
Slides that survive the round trip
Presentation
A .pptx engine that reads the package, resolves layout and master inheritance, and renders the scene — so a deck that came from PowerPoint still looks like the deck that came from PowerPoint after you have edited a title on it.
Reads and writes .pptx · reads .odp, .ppt
A viewer that opens before you blink
Pictures
The double-click app: every common image format, EXIF read and orientation honoured, folder browsing, and PDFs in the same window. Nothing to wait for and nothing to configure.

Crop, correct, annotate, export
Image
A non-destructive editor: the edits are a pipeline over your file, and your original is never written to. Export when you are finished, to the format and size you actually need.
Exports .png, .jpg, .webp
Trim and export without a render farm
Video
Container probing and an edit timeline for the everyday job — trim the ends off, cut the middle out, export. No ffmpeg to install, no native binaries, nothing that needs a toolchain.
Reads what the browser engine decodes · exports .webm
