Udit Mittal

AI engineer

I build AI systems that hold up in production.

RAG pipelines, LLM apps, and the monitoring that keeps them honest.

Things I've built

Pharos

Ask your AI to teach you anything, then check what you actually learned.

Turns any topic into lessons, quizzes, and review. Runs on your own computer, no account.

Code Go · Local LLM

SQL Workbench

Practice SQL in your browser: one file, zero install, fully local.

Drop the bench into any app or open it directly; your data never leaves your machine.

Code TypeScript

India Maps

Maps of India, free to download. Any state, any use.

Country and state maps with district boundaries in GeoJSON and TopoJSON. Browse interactively or take the data.

OpenCodeMap data React · Leaflet

Playlist-Ed

Turns YouTube playlists into distraction-free lessons.

Watch a playlist with progress tracking and a focused player. Study sessions stay on the video.

OpenCode Astro · Svelte
More projects

Lampo

Flip your WiZ bulbs from your phone, instantly, even offline.

Controls bulbs over your own Wi-Fi, so it works without internet or an account. Lights respond right away instead of round-tripping through someone's server.

Code Flutter · Dart

Smokey

A Telegram bot that checks the air you're breathing, worldwide.

Real-time air pollution data in plain chat. Mask recommendations when readings get rough.

OpenCode Python · Flask

Daily Grind

A little office-escape game that runs in any browser tab.

No install, no build. Every sprite and song is generated by code on the spot.

Code JavaScript

Small tools, shipped often

I also build for the AI tooling ecosystem: extensions and small tools around coding agents.
