I Got Tired of Manually Repurposing My Blog Posts, So I Built an AI Tool to Do It For Me

Hey Dev Community!

If you're like me, you enjoy writing technical articles, but you dread the part that comes after: promoting them. The whole process of copy-pasting snippets, reformatting for Twitter, writing a different version for LinkedIn, and then maybe another for Discord... it's a tedious, soul-crushing loop.

I realized I was spending more time on this manual "content logistics" than on writing new articles or coding. There had to be a better way.

So, I decided to build the solution: PostPulsar.

What is PostPulsar?

PostPulsar is a micro-SaaS that uses AI to do the heavy lifting of content repurposing. You give it one blog post, and it gives you back multiple, ready-to-publish posts tailored for different social media platforms.

How it works is simple:

1. Paste your article's URL or raw text.
2. Select your target networks (LinkedIn, Twitter, Instagram, Facebook, Discord, etc.).
3. Click "Pulsar". The AI generates unique posts for each selected network, respecting their different styles and character limits.

You get an editable dashboard with all the generated content, ready for you to review, tweak, and publish.

The Tech Stack

For those interested in the tech, I built this project with a modern serverless stack:

• Frontend: Astro
• Backend & Database: Supabase (Postgres, Auth, and Edge Functions for all the server-side logic)
• Hosting: Vercel
• AI: Gemini

Why I'm Sharing This

I built this tool for myself, but I figured it could be useful for other developers, indie hackers, and tech writers who are building their personal brand or marketing a side project. We should be spending our time creating, not copy-pasting.

I'd love for you to try it out and give me your honest feedback. There's a free plan available so you can see how it works.

Thanks for reading, and I'm here to answer any questions you have

From the website, it's unclear what content will be created. I would suggest illustrating the process, preferably with real input and output, or using graphics to explain it. Including an embedded image or video that was created from a real blog article would be cool, too. At this moment, there's no hook to convince me to sign up, and there's no pricing page or mention of a free trial, so it's hard to tell if the access will always be there or not.

the landing page wasn't doing a good job of showing what PostPulsar
actually does.

Based on your suggestions, I've just pushed a complete overhaul of the page:

• Clarity & Examples: I've added a "See it in Action" section with a before/after example, and a new "Explore the Features" accordion with screenshots to visually walk through the process.
• Pricing & Free Trial: There's now a full pricing section that clearly outlines the free plan (which includes 70 free pulses per month) and the paid options.

That's a quick update! Much easier to understand what it is, thanks!

Hey Enio — this is really cool! 👏

Automating the tedious parts of content distribution is something a lot of creators need, and PostPulsar seems like a clever solution. A few thoughts / questions:

• Love the serverless + Supabase + Vercel stack — did you face any challenges around rate limits or cold starts?
• How do you deal with preserving “voice” or style across each repurposed version (e.g. from blog → tweet → LinkedIn)?
• Are there content types or formats where it struggles (e.g. code snippets, tables, diagrams)?
• Would like to see a side-by-side before/after in different networks to see how different the AI outputs are.

This kind of tool can save hours for indie writers. Kudos for building and sharing it!

This is brilliant — you’ve solved a pain most content creators just accept as normal. Love how PostPulsar automates multi-platform repurposing while keeping each post’s tone authentic. The Astro + Supabase stack is a great combo too 👏

Wow that is clever! Automating blog post repurposing sounds like a huge time saver. How well does it handle different formats like turning posts into threads or summaries?

[Enio Aguiar]

There’s an advanced setting where you can set a character limit per card. The AI will try to generate each post with approximately X characters for each selected network. Sometimes it goes over the limit, sometimes it’s shorter, but you can manually edit the text. X and Threads have a character counter shown after the card is generated. If it appears in red (for example, “-30”), it means the text exceeds the limit, and you can manually shorten it. If you try to publish a post that exceeds the character limit, the system will notify you to fix it before posting. Additionally, you can create prompts, in the pro version there are custom prompts where you can tell AI how you want the text on the cards.

Manually adapting an article into content suitable for different platforms is simply a nightmare.
Now, I extract the key points from the article and write a few prompt phrases, then input them into MindVideo AI. In just a few seconds, I can generate a short video to post on social media. The efficiency is impressive; anyone who uses it knows how great it is!
