Ask HN: What Are You Working On? (Nov 2025)

Historical public companies Merton Probabilities of Default.

A project just for fun and still having to finish a couple of things.

Challenge accepted:

I built an AI generated multilingual storybook, just to see if it would work.

Tap or click the little monster to have it read to you.

Local LLM generated the story, stable-diffusion generated the images, AI converted text to speech in two languages: English and Spanish ( could easily do many more languages ).

It's an open-source iOS voice agent that uses the OpenAI Realtime API (bring your own key).

Current connectors: Hacker News (check demo in readme!), Google Drive, GitHub, and web search.

Arty is self-contained except for the OpenAI model and any third-party services you connect to. Uses local tools—no MCP support yet.

If you'd like additional connectors, feel free to open an issue.
