Francisco Moretti

I'm a Frontend Product Engineer specializing in building AI applications. I'm based in London and originally from Argentina.

I'm currently building an AI law firm at Alaro. Previously, I worked at Samaya AI, building AI for finance.

My open-source work is mostly around the Vercel AI SDK ecosystem. I built ChatJS and AI Registry, and have contributed to AI SDK, Streamdown, AI Elements, and AI SDK Devtools. That work was selected for Guillermo Rauch's OSS Grants, and ChatJS, formerly Sparka, was selected for the Vercel Open Source Program.

Some selected open-source projects include:

ChatJS - An open-source foundation for building AI chat products with auth, models, streaming, tools, sharing, desktop support, and a CLI.
AI Registry - A model explorer for Vercel AI Gateway with provider, context window, pricing, and metadata comparisons.
