How do I install the Knovari PowerPoint add-in? +
Download the add-in from your account dashboard or contact us for the install link. Once you have the manifest file, open PowerPoint, go to Insert → Get Add-ins → My Add-ins → Upload My Add-in, and select the file. Detailed instructions are sent with your welcome email.
Which versions of PowerPoint are supported? +
Knovari supports PowerPoint 2016 and later on Windows and macOS, plus PowerPoint on the Web. Office 365 / Microsoft 365 desktop versions give the best performance.
I cannot sign in. What should I check? +
Confirm you are using the email you registered with, try a password reset, and clear your browser cookies for knovari.io. If you signed up via Google or GitHub, use the same provider to sign in. Still stuck? Send us a note via the form below and include the time you tried and the error message you saw.
How is my slide content stored and processed? +
Decks you upload to Knovari are stored encrypted at rest, processed inside our infrastructure, and never used to train third-party models. See our Privacy Policy for the full breakdown of data flows, retention periods, and sub-processors.
What file types does the Sanitize tool support? +
Sanitize accepts .pptx files. Legacy .ppt files should be re-saved as .pptx in PowerPoint first. Files up to 100 MB are supported in the web app; the desktop add-in handles larger decks.
How do I cancel my subscription or delete my account? +
Email support@knovari.io with your account email and we will action the request within two business days. Account deletion removes all associated decks and metadata; cancellation stops further billing but preserves your data until the end of the current period.
Do you offer team or enterprise plans? +
Yes. We offer team licences with SSO, an admin console, and procurement-friendly contracts. Pick "General enquiry" in the form below and mention team size and timing, and we will get back to you with options.
All systems operational. If you are seeing a problem we have not posted about, please let us know.
