By Serenities · version 3.7.0
What you can do with it
One calendar for every channel
Month, week, day and list views. Drag a post to another day or time slot to move it.
Write once, adjust per channel
Every channel shares the same post until you give one its own text, pictures or comments. One edit for LinkedIn leaves the rest alone.
First comments
Add comments that go up under the post the moment it publishes, where hashtags and links usually go.
Pictures and video from your Drive
Upload new media or pick from your Drive, with folders and search in one picker.
Your AI agents can plan posts
Agents can list your channels and posts, save drafts, schedule posts and cancel them. You choose, per action, whether an agent does it on its own or asks you first.
You see what it can use
The app lists exactly what it can use of your account, and you can turn any of it off.
What your AI agents can do with it
Your Serenities AI agents can use Social Poster for you. You decide, for each of these, whether an agent does it on its own or asks you first.

What’s new
Version 3.7.0 · 2026-09-24
- Your AI agents can plan posts for you: list your channels and posts, save a draft or schedule a post, and cancel one. You choose, per action, whether an agent does it on its own or asks you first (Actions, at the top of the app).
- Social Poster now shows exactly what it can use of your account, and you can turn any of it off (Permissions, at the top of the app).
Version 3.6.0 · 2026-09-09
- Pick channels in bulk — Select all, Clear, or a whole platform in one tap.
- Give any channel its own version of the post: its own text, its own pictures, its own comments. Anything you do not change stays shared, so one edit for LinkedIn does not disturb the rest.
- A channel with its own version is marked "custom" on its tab, and one click puts it back to the shared post.
Version 3.5.1 · 2026-09-09
- Pictures you attach to a post show their preview again, in the composer and on the calendar.
Questions
Which platforms can Social Poster post to?
Bluesky, LinkedIn, Facebook Pages, Instagram, Threads, Pinterest, YouTube and TikTok. You connect each one from the app's Channels page.
Can I post different text to different channels?
Yes. A post is shared by every channel you pick, and any channel can have its own version: its own text, pictures and comments. Anything you do not change stays shared.
Can my AI agents schedule posts?
Yes. Your Serenities AI agents can list channels and posts, save a draft, schedule a post and cancel one. For each action you decide whether the agent does it on its own or asks you first.
Do I have to update the app?
No. New versions arrive on their own, and the app shows what changed.
Where is my data kept?
In a Base of your own in your Serenities account. It stays there if you remove the app.
