About PostNitro
PostNitro is a hosted design tool for social posts, centered on carousels. You start from a topic, an article URL, your own text or a post from X, choose how many slides you want, and it writes and lays them out. Alternatively you can design them yourself in a freeform editor where any element can be dragged anywhere.
A brand kit applies your colors across more than 100 editable templates sized for a 4:5 feed, and you can save customized layouts as your own. Besides carousels it produces image posts and animated video, and finished posts can be scheduled directly to LinkedIn, Instagram, TikTok, Threads and Facebook.
For automation, it can be added to Claude or ChatGPT with OAuth sign-in, or driven from a command line tool installed through npm. The editor can be tried without signing up, and the product is free to start without a credit card.
