One post in. Every platform out.
You make the thing once. ContentSling reshapes it for each place it has to go, puts it on the calendar, and waits for you to say yes.
Reformatting
Every platform gets its own version, not a copy.
A caption that fits Instagram is the wrong length for Bluesky and the wrong shape for YouTube. Posting the same text everywhere is why cross-posting looks like cross-posting.
ContentSling rewrites each one against the rules of the platform it is going to.
- Length. Bluesky counts graphemes, not characters, and cuts at 300. Threads stops at 500. A long post becomes a reply chain instead of being truncated.
- Links. Bluesky needs byte-offset facets or a URL is plain text. Threads auto-links. Instagram does not link at all, so the copy stops promising one.
- Framing. Images are sized per platform, and the parts that matter are kept clear of the interface each app draws on top of them.
- Titles and hashtags. YouTube needs a title. Pinterest needs a title and a destination. Each one is set from the same source content.
Review
Nothing publishes until a person approves it.
Every post waits for you. You see each platform's version exactly as it will appear, change any of them, and approve the ones you are happy with.
There is no setting that turns that off. It is not a preference, it is how the thing is built: content sits in review until someone signs it off, and only then does it take a slot on the calendar.
If a platform cannot publish a particular format, the review screen says so before you approve it rather than failing quietly hours later.
The calendar
Approved content goes out on time, whether or not you are there.
Approved posts take a slot on the content calendar and publish themselves at the right time on every platform. Your computer does not need to be on.
A post that fails is retried, and one that cannot possibly succeed is told apart from one that is just having a bad minute, so you find out early and in plain English rather than reading a platform's error code.
Measurement
Numbers you can actually compare.
Every platform shows you the lifetime count of a post and nothing else, which means two posts from different weeks cannot be compared. ContentSling takes a reading at a fixed age instead, so a post from March and a post from today are measured the same way.
Stills are read at 72 hours. Video is read at 7 days, because a reel keeps accruing plays long after a photo has stopped.
Writing
Draft it yourself, or with Claude.
Write in the app, or connect ContentSling to Claude and draft straight into your calendar. What comes back is a draft like any other: it lands in review, and you decide whether it goes out.
Where your posts go
Publishing today: Instagram, Facebook, Bluesky, Threads, YouTube.
Video means short vertical video: reels, shorts and TikToks. That is the shape all of these platforms take, and it is what lets one piece of content land on every one of them. Long-form video is a different job and ContentSling does not do it.
