I built an AI content repurposing tool and just went live — here's what I've learned so far
Hey everyone! I've been building RepostAI — an AI tool that takes a blog post, article, or transcript and turns it into platform-specific content for 10 different platforms (Twitter, LinkedIn, Instagram, TikTok, Facebook, YouTube Shorts, Pinterest, Reddit, Newsletter, Blog Summary) in seconds.
The problem I kept hitting: I'd write a solid blog post then spend an hour manually rewriting it for every social platform. Each one needs a different hook, tone, length, and format. So I built something to automate that part.
It's live now at getrepostai.com with a free tier (5 repurposes/month) so anyone can try it.
A few things I've learned launching this:
Reddit karma gating is brutal when you're new. Most subreddits auto-remove your posts
Quora answers are surprisingly good for long-term SEO traffic
Twitter/X build in public posts get genuine engagement if you're not just spamming links
The hardest part isn't building — it's getting those first users
Still at zero paying customers so this is very much day one. Would love any feedback on the product or advice on early traction from anyone who's been through this stage.
I learned the same thing on launch, zero users is less about shipping speed and more about showing one concrete before-and-after workflow people instantly get. I still bounce between ChatGPT for raw input and Buffer later, but I built PostPilot because the real pain for me was turning one blog into native drafts without babysitting every hook, tbh. Are the free-tier users sticking on one platform first or trying all ten at once?
"Solving the 'one post, ten platforms' headache is a classic high-value play, James. The real magic isn't just the AI—it's getting the specific hooks and formatting right for each platform so the content doesn't just look like a copy-paste job.
Building in public on X is definitely the way to go for early traction with this. Your launch and the 'platform-specific content' focus would actually make for a great entry in the current competition. Entry is $19 and the winner gets a trip to Tokyo.
Prize pool just opened at $0. Your odds are the best right now. Definitely worth a look while you're grinding out those first paying customers!
Have you considered adding a bulk-upload feature for old blog archives? That could be a huge 'wow' moment for new users."
