Katopost publishes through each platform's official API and follows their security guidelines ā we never ask for your password or sign in as you. Connecting an account is an OAuth handshake on the platform's own site, we store only the resulting token, and you can revoke it from Katopost or from the platform at any time.
You can create an account, connect your first platform and publish without entering a card. Paid plans raise the monthly publishing allowance and unlock scheduling further ahead ā the current plans and prices are in the table above.
A repost rule takes a video you have already published and sends it out again ā either mirrored to your other connected platforms, or re-shared later to catch a different audience. You keep one upload and one caption; Katopost creates a separate task per platform, so one failure never hides the posts that worked.
Not yet. There is no iOS or Android app today, but the web app is built mobile-first ā you can upload, caption, schedule and check on a post from your phone's browser, and you can add it to your home screen.
MP4, MOV and WebM. Each platform then applies its own rules on top ā length, aspect ratio and file size ā so Katopost checks your video against the targets you picked before it queues anything, rather than failing halfway through publishing.
