PostRoast - AI insights to improve your post performance

Hi all;

I built PostRoast – an AI-powered post analyzer – in 2 hours. Now it’s analyzing X posts & used by many users!

The Problem

Creating viral, high-performing social content is hard. Most creators struggle with knowing what actually makes a post work. You post, hope for engagement, and maybe tweak next time – but the feedback loop is slow, vague, and often discouraging.

There are tools out there, but they’re bloated, expensive, or built for teams—not individuals just trying to improve fast.

The Solution: PostRoast

I wanted something radically simple. In just 2 hours, I built PostRoast.app — a 100% free AI tool that roasts your social posts (with a bit of sass) and gives you actionable feedback instantly.

Here’s how it works:

Paste your post (X/Twitter, LinkedIn, etc.)
The AI "roasts" it – scoring clarity, engagement, and virality
Then it gives smart, specific suggestions to improve it
You can also study how top creators like Justin Welsh, Dickie Bush, and others write their content
It’s simple, fast, and honestly kind of addictive.

Traction So Far

Since launching, it’s taken off way faster than I expected:

Built in 2 hours
many of users (and growing daily)
Now analyzing X posts (with more platforms to come)
100% free
Avg session time is surprisingly high (creators really get into optimizing)

What Makes It Different

Most AI writing tools generate content. PostRoast is about improving what you've already written — helping creators sharpen their voice, boost engagement, and learn fast from what actually works.

Plus, it’s free, instant, and doesn’t require logging in.
