Post to All Platforms at Once
You're on X, Threads, Mastodon, Bluesky, and LinkedIn. Here's how to post to all of them without opening 5 tabs.
The problem in one paragraph
You're on X, Threads, Mastodon, and Bluesky. Each post needs to be entered separately. That's 4 tabs, 4 character limits, 4 times every day.
Open X, paste your post, tweak the hashtags. Switch to LinkedIn, paste again, rewrite the tone. Open Bluesky, is it the app or the website? Find the tab, type it from memory. By the time you're done, 30 minutes have passed and you haven't done any actual work.
Most founders do this 2-3 times a day. That's over an hour lost to copy-pasting. Every. Single. Day.
One editor, all your platforms
In Shaflex, you write your post once and toggle on the platforms you want. Hit publish and it goes live on X, Threads, Mastodon, Bluesky, and LinkedIn at the same time.
