What PostNitro is

PostNitro is a design engine for social content. It writes and designs carousel posts, single images and short animated video on a brand kit, then publishes them natively rather than reminding you to post.

Input can be a topic, raw text, an article URL or an X thread.

What you can do with it

Generate carousel posts from an idea or URL
Design single-image posts and animated video
Apply a brand kit for consistent output
Schedule native publishing to four networks
Export PNG, PDF, MP4 or an editable design

Who it is for

LinkedIn and Instagram creators
Marketing teams publishing carousels
Agencies producing for clients
Teams driving design from an AI agent

What to watch out for

Video output is rendered slides, not generative video
X is a content source and export format, not a publishing destination
Scheduling and connected accounts start on a higher plan
Brand review is still needed before publishing
