Publishing

Post your clips without leaving the tool that made them

A clip that stays in a download folder was not worth making. Katto connects to seven platforms directly, so a finished clip goes out from the same place it was cut, either straight away or on a schedule.

Seven destinations, connected once

Each one is a real account connection you authorise yourself. Katto uploads the video file; it does not hand your clip to a third-party automation service on the way.

YouTube Shorts

Uploads to your channel. Verified OAuth, so no unverified-app screen and no 100-user cap.

TikTok

Posts to your profile. See the note below: it lands privately until our app review clears.

Instagram Reels

Publishes a Reel through Instagram Login, no Facebook Page required.

LinkedIn

Posts the video to your member profile, live rather than as a draft.

Bluesky

Native video via AT Protocol. Sign in with a handle and an app password.

Mastodon

Native video on your own instance. Sign in with the instance URL and a token.

Threads

Publishes through Threads Login, same model as Instagram.

The honest part, about TikTok

TikTok gates public posting behind a content-posting review. Ours is submitted and not yet approved, and until it is, TikTok itself forces every upload from our app to private visibility, whatever we ask for. Your clip arrives on your profile and you publish it in one tap. We mention it here rather than in a support reply, because a publishing feature that quietly posts nothing visible is worse than one that tells you where it stops.

Or put it on the calendar

Posting five clips the day an episode drops buries four of them. The calendar view takes a finished clip, a platform and a slot; drag an entry to move it, and a scheduler sends it when it is due. A post that fails, because a token expired or a platform was having a moment, stays visible and can be retried instead of disappearing.

What is not here

Facebook Pages and X are built and switched off. Facebook needs a business entity and an app review that a solo founder does not clear in a weekend; X charges for the API tier that allows video upload, and the volume does not justify it yet. They are listed as inactive in the product rather than shown as coming soon, because a greyed-out button you can press is a support ticket waiting to happen.

Questions

Do I need Zapier or Buffer in the middle?

No. The connections are yours and the upload happens from Katto. The reason this page exists is that the tools most often recommended for automated posting are general automation platforms that do not make the video.

What happens with TikTok?

The post reaches your profile, but TikTok forces private visibility for apps whose content-posting review has not cleared yet, and ours is pending. So treat it as a staged upload: it is there, in your account, waiting for you to make it public. We would rather say that than let you find out.

Can I schedule instead of posting now?

Yes. Pick a slot on the calendar, drag it to move it, and a scheduler publishes it when it is due. Failed posts can be retried from the same view.

Why no Facebook or X?

Facebook Pages need a business entity and an app review that a solo founder cannot clear quickly, and X requires a paid API tier for video upload that the volume does not justify yet. Both are built but switched off rather than half-working.

Does publishing use my monthly quota?

No. The quota counts source videos you turn into clips. Publishing a clip you already made costs nothing.

Make the clips, then send them

Publishing does not use your monthly quota. It counts source videos, so posting a clip you already made costs nothing.
