The problem
Sharing one update means rewriting it for every network, then opening each app to post it. Postka takes one rough idea (“What did you ship, fix, or learn?”) and carries it all the way to a published post.
Postka
Turn one rough idea into posts for 11 channels in your own voice, then post or schedule them straight from the draft, through Repliz.

What it does
- One idea, a draft per channel, in each network’s own format: posts and threads, carousel slides, pins, short-video scripts and articles.
- Your own voice, learned from your real writing, with a separate profile for each project.
- Images, pasted in or drawn from the draft.
- Post or schedule from the draft, to your connected accounts through Repliz. Nothing goes out until you press the button.
