Show HN: I built my first SaaS

https://www.lunatic-ai.com
2•fhouser•2h ago
Hi everyone, second Submission, first SaaS, longtime HN reader.

TL;DR: This is a LinkedIn post generator.

If you are active on LinkedIn or other heavily text-based social media platforms, then you might find this interesting.

Bleeding edge technical highlights: - AI-SEO, or, "GEO": We use a so-called "grounding page" for presenting facts and non-facts about the website to help non-human readers "ground" themselves in the truth of the matter.

What I learned: - Agent-based coding is a massive boost and accelerator if you take the time to properly review results and keep everything on track.

Let me know what you think!
