Ten engines, each with its own home and templates.

Every engine opens to its own templates and your files for it, so nothing piles into one crowded screen. Turn a workbook into a document, a PDF into a spreadsheet, or a document into slides whenever the data needs a new shape.

Create

DocsLetters, reports, résumés and contracts with a full ribbon, styles, tables, mail merge, contents pages and line numbers.
SlidesPresentations with themes, layouts, shapes, charts, speaker notes and a full-screen presenter.
SheetsWorkbooks with formulas, number formats, charts, sorting, frozen panes and many sheets.
PublisherFlyers, brochures, cards, menus, certificates and signs laid out for print.
ProposalsClient proposals with pricing tables, optional items, variables, branding and signed acceptance.

Work with files

PDFOpen any PDF to reorder, extract, rotate, merge, split, annotate, sign, fill forms, stamp and compress.
ConvertChange files between formats and make them smaller, one file or a whole batch.

Build

CodeOpen a project folder, edit with a full code editor, search and replace, and run its tests.
TerminalCommand sessions in PowerShell, Command Prompt, Bash and the other shells on your computer.

Protect

VaultAn encrypted store for passwords and keys that finds them in your files, sorts them and keeps them hidden until you reveal one.

Made for real work, not demos.

Pick an engine to see it.

    Seal it once. Check it any time.

    Every document shows a live fingerprint of its exact contents. Sealing writes a packet you can keep, send or archive, and verifying it rebuilds the PDF from the document and compares every byte.

    Make

    Write, design or price in any engine. The layout is computed the same way on every computer, so pages break in the same places everywhere.

    Seal

    One click stores the document, its exact page layout, the PDF and the fonts used, each with a SHA-256 fingerprint.

    Verify

    Re-check the fingerprints and re-create the PDF from scratch. If anything changed, you will know exactly which file.

    Download

    Everything runs on your computer. Your files stay in your own data folder and nothing is sent anywhere.

    Windows

    Windows 10 or 11, 64-bit. The installer adds a Start menu entry; the portable version runs from any folder.
