Publishes to all 11 platforms: LinkedIn, Instagram, Facebook, X, YouTube, TikTok, Pinterest, Threads, Google Business, Bluesky and Mastodon.

Why Threads posting slips
Posting when you remember
Threads rewards a steady rhythm, and posting in bursts then stopping resets it.
Finding out at the last minute
A caption over Threads's limit, or the wrong kind of media, is only refused when you press Post.
One app per platform
Opening Threads, then every other app, to post the same news is slow and easy to forget.
How Optimate schedules Threads
Write it once, check it against Threads's own rules, and pick a time. It publishes while you get on with your day.
One calendar for every platform
Threads sits on the same planner as LinkedIn, Instagram, Facebook, X, YouTube, TikTok, Pinterest, Google Business, Bluesky and Mastodon.
Checked against Threads's rules
The caption is counted as you type and the media checked before it is queued, so a post Threads would refuse is caught before it is scheduled.
Tailored per platform
Post the same news everywhere, with the wording adjusted for Threads, and preview it the way Threads will show it.
Post now or later
Pick a time, or publish straight away when something can't wait.

Common questions
Can I schedule Threads posts for free?
Yes. Every new account starts with a 14-day free trial, no card needed, and the Free plan afterwards keeps a small queue of scheduled posts.
What is Threads's character limit?
500 characters for a post or caption. Optimate counts as you type and warns before you schedule anything Threads would refuse.
What can I attach to a Threads post?
Text, one image or video, or a carousel of up to 20 photos and videos. Threads videos up to 5 minutes.
Can I post the same thing to Threads and other platforms?
Yes. Write one post, tick every platform it should go to, and adjust the wording for each one before it is scheduled.
Threads image sizes
Every size Threads asks for, from posts to profile pictures, on one page with every other platform's.
