🗣️ Post 1: Show HN: I Turned a Claude Artifact into a SaaS – Lessons from an LLM Wrapper
As posted by: maxtermed | 🔥 Points: 3
💬 Summary
Earlier this month I was playing with one of Claude's "inspiration" Artifacts, a bedtime story generator (a React component that runs in the browser). I showed it to a mom I know. She said "This is nice, but it would be great if it could make my child the hero of the story and narrate it so we can listen together."
That offhand comment launched a 2-weeks learning journey from a simple React component to a full production SaaS.
This technical journey taught me that "just an LLM wrapper" is like saying a restaurant is "just a kitchen." Here's how I built it:
Stack: FastAPI + SQLAlchemy + Auth0 + Stripe + OpenAI API
- Multi-step wizard flow with session management
- Background audio generation with OpenAI TTS
- User auth, subscription tiers, usage tracking
- Rate limiting, input sanitization, secure file storage
- Database migrations, monitoring, deployment scripts
The non-obvious challenges:
- Prompt engineering to make the child the hero of the stories
- Voice selection and prompts to find a tone that doesn't terrify kids at bedtime
- Session state across wizard steps without losing progress
- Handling OpenAI API failures gracefully
- Storage for generated audio files
- Making it parents and grandparent-friendly
Claude Code helped throughout, as a senior engineer to bounce ideas off and to write quite a bit of code. I reviewed, understood, and sometime rewritten every block of code. The learning was the point, in this case.
The humbling realization: Yes, it's "just" an LLM wrapper. But so is ChatGPT. The value isn't in the AI call - it's in solving a specific problem for specific people and package it in a user-friendly way. Parents don't care about tech stacks. They care that bedtime takes 20 minutes instead of 2 hours.

🗣️ Post 2: Show HN: Legal Eyes – Turn casual text into legalese with one click
As posted by: jamsey | 🔥 Points: 1
💬 Summary
Hey HN,
I built a Chrome extension called Legal Eyes that rewrites your casual messages into sharp, professional legal language.
Use cases: - Freelancers chasing late invoices - Founders dealing with vague contract terms - Anyone trying to sound more serious or formal (without being a lawyer)
No prompt engineering, no copy-pasting. It sits in your browser, and converts selected text with a click. I built it using React, Supabase (for auth and usage tracking), OpenAI (for the rewriting), and deployed via Vercel.
I launched this to help the little guys when they need a stronger voice. I hope this goes out into the world and helps someone :)
Would love your feedback on: - Features you'd expect in v2 - Thoughts on monetizing vs keeping it free - Weird or niche use cases I haven’t thought of

Thanks! Happy to answer anything.
