How I built AutoPostMode: an AI that researches, writes and posts to X and LinkedIn

Description and use

AutoPostMode automates research, writing, image creation, and scheduled posting to X and LinkedIn, saving the author hours each week.

Problem

The author lost hours weekly repeating the loop of finding topics, writing, creating images, and scheduling posts.

Outcome

AutoPostMode reduces manual effort by automating content research, creation, image design, and scheduled publishing to X and LinkedIn.

Workflow

• Research trending topics in the user’s niche
• Write posts in the user’s voice
• Design image cards for the posts
• Publish to X and LinkedIn at optimal times

Evidence

I kept losing hours every week to the same loop: find something worth posting about, write it, make an image, then remember to post at a good time.

Backend: Python with FastAPI. It's fast to build with, and the auto-generated docs made testing endpoints easy.

Frontend: plain HTML, CSS and JavaScript. No framework, so pages stay light and quick.

Free tools are a better first touch than a signup wall.

A post only sounds like you if the AI has real examples of your writing to learn from.
