Which platforms it posts to today

Which platforms can it post to today?

Seven platforms publish today: Facebook, Instagram, TikTok, X, YouTube, LinkedIn and Snapchat, each on a page or account you own. Facebook, Instagram, TikTok and X publish through your own logged in browser session, and each of those four has run daily on real pages.

Pinterest is not started. Not in beta, not partially working, not a few weeks away. We write it this way because the alternative is a logo wall that implies parity, and the person who gets hurt by that is the one who signs up for a network we cannot post to.

What does a proven run mean here?

It means the platform has actually published, repeatedly, on a real page, and only a platform with a proven run is listed as working here while everything else says so plainly. Seven platforms are listed as live on that basis, and Pinterest is not.

The engine that finds the story, writes it and renders it is the same for every platform; what differs is the delivery route at the end, and a delivery route is the part that either works reliably or quietly does not. Writing an adapter takes a week. Trusting it with somebody’s page takes weeks of daily posts that went out on time and looked right. The live rows above have that behind them, across text, image and video posts. Four of them have their own page so far: Facebook, Instagram, TikTok and X.

Does it use the official API or a browser session?

A browser session, on Facebook, Instagram, TikTok and X. We hold no official API certification on any network today, and we will say so per platform rather than in general terms.

In practice that means posting happens as you, from a browser that is already signed in to your own account. You are not handing us credentials to store, and nothing is routed through a shared or third party account. The controls that sit around that route are on trust and account safety.

What changes when an official API is certified?

The delivery route changes and the rest of the run does not. Finding the story, writing it, rendering it into a format and the text limit check all happen upstream of delivery, so a certified API swaps in underneath them without changing how you work.

What it would change for you is the reliability story and, on some networks, what kinds of post are allowed at all. When that happens on a platform, its row in the table above changes and the change is written down publicly. Until it happens, the row says browser session.

Can TikTok posting and Instagram Reels be automated?

Yes, and both run today. TikTok publishes video posts and multi image photo posts, Instagram publishes single image, carousel and video posts, each through your own signed in session, each rendered into a format with declared text limits before it goes out.

Both networks have their own rules about automated publishing, and both have native scheduling tools that are free and worth knowing about. The difference is the work in front of the send: the native tools post what you already made, and Content OS finds today’s story, writes it and renders it before it posts. What each platform permits in general is a separate question from what we support, and the per platform pages say plainly what is and is not in scope.

Is posting through a browser session safe?

Nobody can promise that an account is safe, whatever route a tool uses. Browser session posting is a grey area and we are not going to describe it as approved.

What we do instead is keep the behaviour slow and boring. Volume is capped per page per day, timing is varied rather than landing on the same second, one posting session runs per machine so two processes never collide, and a post that breaks its format’s text limits is parked for a person instead of posting. We do not automate comments, DMs, follows or likes at all, which is where most restriction stories actually begin. The full reasoning is on trust, the run itself is on how it works, and the rest of the questions are on the FAQ.
