Knowledge Sync is how your genie stays up to date on your business — your policies, prices, products, and anything else customers ask about — without anyone having to manually retrain it. ## What you can sync from * **A spreadsheet** — point Sync at a Google Sheet and every row becomes something your genie can answer from. * **An API** — pull structured data straight from your own systems. * **A web page** — hand Sync a URL and it reads the page into your genie's knowledge. * **A custom database or app** — anything you've already connected (see [Connections](/sync-guide/connections)) can be used as a knowledge source.

When a sync runs, your genie's knowledge updates automatically; there's nothing to re-upload and nothing to retrain. Schedule picker on a knowledge sync configuration ## Checking on a sync Every sync's page shows you when it last ran, whether it succeeded, and how much information it brought in. If a sync fails — say, a spreadsheet was moved or an API went down — you'll see that clearly, and can fix the source and try again without waiting for the next scheduled run. ## Before tab, per genie You can manage all your knowledge syncs in one place, or from a specific genie's **Before** tab if you only want to see what's feeding that genie.
