Getting started

1. Choose X on Connected socials.
2. Sign in to X and approve the access it asks for — reading your profile, posting, and uploading media.

X posts run to 280 characters, or 25,000 if your account has X Premium. Posttyy checks with X, so there's nothing to switch on. A post can carry up to 4 photos, one GIF, or one video. X is the only network here that publishes GIFs.

1. In the Instagram app, open Settings → Account type and tools and switch to a Business or Creator account. It's free, it takes a minute, and you can switch back whenever you like.
2. Choose Instagram on Connected socials.
3. Sign in and approve both permissions — the second one is what lets Posttyy publish. Leaving it unticked is the most common reason an Instagram connection exists but won't post.

Instagram takes photos and video, but no GIFs. A post can carry up to 10 photos as a carousel, or one video. Captions run to 2,200 characters.

1. Choose Threads on Connected socials.
2. Sign in with the Threads account you want to post from, and approve both permissions — publishing is the second tick here too.

A Threads connection is its own account, even though Threads and Instagram share a login. Connecting one does not connect the other, and you can have either without the other. Posts run to 500 characters, with up to 10 photos or one video.

1. Make sure the Facebook account you'll sign in with manages at least one Page. If it manages none, there is nothing for Posttyy to post to and the connect stops there and says so.
2. Choose Facebook Page on Connected socials.
3. Sign in to Facebook and, on the screen asking which Pages the app may use, tick every Page you want to post to.
4. If that login manages more than one Page, Posttyy then asks which of them you want to post to. Each Page you tick becomes its own connection, listed separately.

Facebook is asked which Pages to grant every time you connect, even if you've connected before. That's deliberate: Facebook otherwise reuses your last answer, and a Page created since then could never be reached. So if you add a Page later, connect Facebook again and tick the new one.

1. Choose TikTok on Connected socials.
2. Sign in to TikTok and approve access — including permission to post and to send posts to your TikTok Inbox.

A TikTok post is photos or one video. Up to 35 photos publish as a photo post — one photo on its own, or several as a swipeable carousel — and a video publishes as a video. Not both on one post. TikTok takes JPEG and WEBP photos; a PNG is converted on the way in. Captions run to 2,200 characters, and on a photo post the caption's first line also becomes the title.

Each TikTok post asks you a few questions. When you tick a TikTok account, Posttyy shows the name the post goes out under and asks who can see it, whether people may comment, and whether it promotes a brand. A video also asks about Duet and Stitch; a photo post asks instead whether TikTok may add a recommended track behind the photos, which it won't do unless you say so. Nothing is chosen for you — that's TikTok's rule. The post can't be scheduled until you choose who can see it.

Or send it to your TikTok inbox. Choose “Send to TikTok inbox” and Posttyy sends the post to your TikTok app, not to your profile. It arrives as a notification in the Inbox tab of the TikTok app — not in your Drafts folder. Tap it to add music, edit the post, choose who can see it and post it. A video goes without its caption, because TikTok doesn't accept one this way, so you write it in the app; photos keep theirs. TikTok allows 5 posts waiting in your Inbox in any 24 hours.

1. Choose LinkedIn on Connected socials.
2. Sign in to LinkedIn and allow Posttyy to post on your behalf.

LinkedIn sign-ins expire after 60 days. Every other platform here refreshes itself in the background; LinkedIn only allows that for companies it has approved as marketing partners, so roughly every two months the connection stops and you reconnect it on Connected socials. Posttyy marks it clearly when that happens, and nothing scheduled is lost — the posts wait.

Photographs, not video. A LinkedIn post can carry up to ten images, or none at all — words on their own publish fine. Video is not supported yet. Posts run to 3,000 characters.

It posts as you, not as a company page. Publishing to a LinkedIn company page needs a separate permission that LinkedIn grants case by case, so for now a LinkedIn connection is your own profile.

1. Choose Pinterest on Connected socials.
2. Sign in to Pinterest and allow Posttyy to see your boards and create pins.

A pin goes on a board, so the post picks the boards. Connecting Pinterest connects your account, like every other network here — it's one account and counts as one. Tick Pinterest on a post and its Pinterest settingsdropdown shows a row of your boards; choose one, or several, and the post is pinned to each of them. The same dropdown takes an optional pin title and a link for people to tap through to. Boards you keep secret aren't offered: Posttyy doesn't ask Pinterest for permission to see them. Need a board that isn't there? Choose “+ New board” at the end of the row: Posttyy makes it on Pinterest and ticks it for the post.

A board made on Pinterest takes up to an hour to appear. Posttyy keeps a copy of your board list so the composer opens straight away instead of waiting on Pinterest, and refreshes it every hour. Made a board on Pinterest and want it now? Connect Pinterest again — that reads the list immediately. A board made with “+ New board” shows up straight away.

Photographs, and at least one. A pin is a picture, so a Pinterest post can't be words alone. One image is a plain pin and two to five make a carousel. Video and GIFs aren't supported yet. Descriptions run to 800 characters. A post pinned to several boards makes a pin on each, and the post links to the first of them.

Pinterest isn't publishing yet. Pinterest doesn't let an app it hasn't reviewed create pins on real accounts — not privately, not at all — and it hasn't finished reviewing Posttyy. You can connect Pinterest and schedule to it, and those posts will say so plainly rather than failing quietly. Everything starts working the day the review passes, with nothing to change at your end.

1. Choose YouTube on Connected socials.
2. Sign in with the Google account your channel belongs to, and allow Posttyy to upload videos and see the channel.

It connects a channel, not a Google account. Google signs you in as whichever channel that account is currently acting as, so if you run several, switch to the right one on youtube.com before connecting. A Google account with no channel can't be connected at all — make one at youtube.com first. To add a second channel, switch to it and connect again; each counts as one account.

A title of its own. YouTube wants a title and a description where every other network here wants one caption. So ticking a YouTube account adds a YouTube settingsdropdown under the caption, with the title box in it, and the post's caption becomes the description. Posting to several channels at once? Each gets its own title box, so the same video can be titled differently on each. Titles run to 100 characters, descriptions to 5,000.

A video, and a title for it. A YouTube post is a video — MP4 or MOV, one per post, no photographs — and it can't go out untitled, because YouTube won't publish a video without one. The description is optional. How long a video may run is your channel's business rather than Posttyy's: fifteen minutes until you verify a phone number with YouTube, twelve hours after that.

Short or ordinary video isn't a choice. YouTube decides, and it decides from the file: upright or square and three minutes or under becomes a Short, anything wider or longer becomes an ordinary video. There is no switch for it in YouTube itself and none in Posttyy. What Posttyy does is tell you which one you're about to get, under the video, before it goes.

Tags, a category, an AI label and a thumbnail. The same dropdown holds the rest of what YouTube asks. Tags are words that help people find the video, separated by commas, up to 500 characters in all. Every video is filed under a category, from the list that channel can use — People & Blogs to start with, which is what YouTube's own uploader defaults to. Switch on Altered or AI-Generated Content if the video has realistic altered or synthetic content; YouTube may show viewers a label. And you can add a picture to front the video: a JPEG or PNG up to 2 MB. All of these belong to the channel rather than the post, so a video going to two channels can be set up differently on each.

Thumbnails need a verified channel. YouTube only accepts a custom thumbnail from a verified account, and custom thumbnails for Shorts are currently added in YouTube Studio on a computer. Where it won't take yours the video still publishes normally — YouTube picks a frame from it, the same as if you'd added no picture at all. Posttyy can't tell in advance which channels qualify, so it doesn't pretend to.

Videos go out public. Google verified Posttyy's access to YouTube on 12 September 2026. Before that every video uploaded through it was locked to private, whatever it asked for; since then a published video is public, watchable by anyone with the link and listed on your channel like any other upload. You can still change a video to unlisted or private yourself in YouTube Studio afterwards.
