OnePost Broadcast Desk

Write once, then send the same post, image or video to 20 channels from one place, all tied to your single mobile number and email.

Find my accounts

Check which platforms already have an account on your mobile number. Each check opens that platform's own "find your account" page with your number copied. Enter it there: if the platform recognises it, it sends a code to your phone.

Found accounts are ticked in Channels automatically. Platforms marked "Not here" get a Sign up link. This only works for a number you own, because each platform sends its code to that phone.

Platforms don't accept files through share links. Keep these on your phone: when each app opens, tap its attach button and pick the same files. Your caption is already copied.

        How "one click" works here
        
    
          
  1. Enter your mobile number and email once. Sign up or log in on each platform with them.
    2. 
          
  2. Write the post, add a link and hashtags. Short-limit channels (X, Bluesky, YouTube title) get an auto-trimmed version.
    3. 
          
  3. Tap the green button. It walks through every ticked channel in order and marks each one sent.
    4. 
          
  4. Channels with direct share links open with your text filled in. Instagram, Shorts, Snapchat, Vimeo, WeChat and Ads open their upload page with the caption on your clipboard: paste and attach your media.
    5. 
          
  5. Browsers block a single tap from opening 20 tabs at once, which is why it moves one channel per tap.
