Frequently asked questions
Answers to common questions about Kazi OS: price, offline use, file storage, Microsoft Office compatibility, accounts, email, AI and devices.
Is Kazi OS really free?
Yes. Docs, Sheets, Slides, PDF, Notes, Forms and Draw are free, with no signup and no credit card. A free Kazi account adds your @kazios.app email address, Kazi AI (10 million tokens a month) and cloud sync.
Does Kazi work without internet?
Yes. After your first visit the app is stored on your device, and your files are saved on your device. You can create, edit, print and export with no connection. Email, Kazi AI and sync catch up when you're back online. See Offline and sync.
Where are my files stored?
In your browser's storage on your own device. Nothing is uploaded unless you sync, share, email a file or send content to Kazi AI. Clearing your browser's site data deletes files that are only on that device, so use sync or backups.
Can I open and save Word, Excel and PowerPoint files?
Yes. Kazi opens .docx, .xlsx and .pptx files and exports Word, PowerPoint, PDF, CSV and Markdown. See Import and export.
Do I need to install anything?
No. Kazi runs in any modern browser. Installing it as an app is optional and gives you a desktop or home-screen icon and instant offline start.
Which devices are supported?
Windows, macOS, Linux, ChromeOS, Android, iPhone and iPad, in Chrome, Edge, Firefox, Safari, Brave or Opera.
Is my @kazios.app email a real email address?
Yes. It sends and receives with anyone, and works in phone and desktop mail apps. See Your @kazios.app address.
Can I change my @kazios.app handle?
Not at the moment. Choose carefully when you sign up. If you need a different address, create a new account.
I forgot my Master Password. What now?
Kazi can't see your Master Password. Try every password manager and browser where you might have saved it. Contact support@kazios.app from your recovery email address for help.
Does Kazi AI read my files?
Only what you send it when you ask. See Kazi AI privacy.
How do I get help?
