Posts for founders, written from your code

As you build, Postboard turns what you ship into a Substack article and posts for X, LinkedIn and Instagram, in your voice, ready for you to edit.

Free, from the team behind QTR

Ideas from your code

Point it at your repo and ask for ideas, or let Claude Code add one each time you ship.

One idea, every channel

An idea becomes a Substack article, then posts for X, LinkedIn, Instagram, Reddit and more.

In your voice

Tell it who you write for and how you talk, and every draft sounds like you.

Images from your app

Screenshots, cards, GIFs and short videos, made from your real app and code.

Edit with AI, or by hand

Ask AI to change any post, image or line, or just type. It asks before it acts.

Yours, on your Mac

Plain markdown files in a folder, with the full history of every post.

Free, because we’re founders too

We built Postboard for ourselves at QTR, and we use it for every launch and update we write about. It’s a premium tool, and it’s yours for free.
