Share link & shortcuts

The idea

tinyposter has a special page at /post. Open it with a few URL parameters and it pre-fills a one-tap composer. Confirm and the post goes live.

You stay logged in via your normal browser session, no API token needed for this path. That means it works from any device where you're signed into tinyposter.app.

The URL format

https://tinyposter.app/post?text=YOUR_TEXT&platforms=TWITTER,LINKEDIN

# Optional extras:
# &at=2026-05-03T13:00:00Z   schedule for later
# &media=https://...,https://...   image/video URLs
# &title=Optional title             used for video titles

That's it. The page handles URL-encoding the values you pass.

Use cases

1. 01

   Browser bookmark / bookmarklet

   Highlight some text on any web page, hit your bookmark, and tinyposter opens with that text pre-loaded.

   Add this as a bookmark, bookmark name “Post to tinyposter”, URL:

   javascript

   Copy

   javascript:(()=>{const t=window.getSelection().toString()||document.title;window.open('https://tinyposter.app/post?text='+encodeURIComponent(t)+'&platforms=TWITTER',_blank)})();

   Now select text on any page, click the bookmark, and you get a tinyposter composer with that text.

2. 02

   iOS Shortcut, quick post from anywhere

   Make a Shortcut that posts whatever you type or share:

   1. Open the Shortcuts app on iPhone.
   2. Tap + to make a new one.
   3. Add action: Ask for Input → set prompt to “What to post?”
   4. Add action: URL → paste:
      text

      Copy

      https://tinyposter.app/post?text=[Provided Input]&platforms=TWITTER,LINKEDIN

      Replace [Provided Input] with the magic variable from the previous step.
   5. Add action: Open URL.
   6. Name it “Post,” pick an icon, and add it to your home screen.

   Now you tap the icon, type the post, hit go, confirm in Safari, done.

3. 03

   iOS Share Sheet, post things you read

   Make a second Shortcut that takes whatever you're sharing (text, URL, etc.) and pre-fills it.

   1. New Shortcut → toggle Show in Share Sheet → accept Text and URLs.
   2. Action: Get Contents of Shortcut Input.
   3. Action: URL → paste:
      text

      Copy

      https://tinyposter.app/post?text=[Shortcut Input]&platforms=THREADS,BLUESKY

   4. Action: Open URL.

   Now in any app, tap Share → tinyposter and you go straight to a pre-filled composer.

4. 04

   Android Tasker / Web Intent

   Same idea on Android. In Tasker (or any automation app), build a task that opens a URL with the same query string. Or use a home-screen widget that opens the URL directly.
