Write it once, pick when, walk away.
Three steps, then you’re done.
No streaks to keep. No badges to clear. You queue the week and the posts go out on their own.
Write it once
One editor. Type the post, then tailor it per platform if you want. A thread for X, a single line for LinkedIn. No pasting the same words four times.
Pick a time
Say when. Tonight, Tuesday, 7am next month. Drafts and auto-save hold everything, so you can close the tab mid-sentence and it waits.
Walk away
At the minute you set, every account gets its version. You don’t log in, you don’t confirm, you don’t watch. The calendar has the week if you ever care to look.

Hi, Richard here 👋
I have always wanted to build a social media scheduler, ever since I started posting on multiple platforms.
Many platforms are priced per account, have crazy expensive plans, and most of them were completely unusable on mobile, even if they had a dedicated native app.
This was my main motivation to build StormScribe, and later LetterBox, when I found out what I exactly want. StormScribe was rough, but 35 people stuck with it, and I moved every one of them over to LetterBox.
Now I am opening it up to You.
Post once. Find out what lands.
Schedule to every platform, then let the signals tell you where you actually resonate, not just where the follower count is highest.
