Two drafts ready for you to review and send.
One workspace.

Zanostack is in active development. Join the waitlist and we’ll email you when access becomes available. There’s no announced release date yet, and joining does not guarantee access.
We’re building native desktop apps for macOS, Windows, and Linux, with local files at the heart of the experience. Platform availability will be confirmed at release.
The suite is designed to open, edit, and save files on your device. Some AI features will need online processing. We’ll explain how the app handles your data in its launch privacy policy. Website analytics is separate and only enabled with your consent.
Core editing is being built to work offline. Online AI features will need an internet connection. We’ll confirm offline capabilities and access requirements at launch.
We’re building around familiar formats: DOCX, XLSX, PPTX, PDF, Markdown, and HTML. Format compatibility and conversions are part of the work in progress and will be confirmed at launch.
Zanostack will be a paid app with limited free access. Pricing, included features, and free-access limits will be shared before launch. Joining the waitlist is free and does not commit you to a purchase.
We’re building an office that works with you.
