# Andrew Ng is using Claude Code, OpenAI Codex, Gemini CLI.

My analyst and data scientist friends - are you?

And no, I don't mean copy-pasting from ChatGPT. I mean Claude Code, Cursor, Gemini CLI - the agentic AI coding tools.

## What they let you do

Build full analytics apps. React frontends, database backends, multi-user dashboards. Deploy on your company VPN or bundle as single-file HTML. Go way beyond Excel/VBA. Large codebases get done many times faster. Even for ML model work, Mito AI works inside Jupyter - proper agentic iteration.

I've taken client projects I would've declined two years ago. Built [app.tigzig.com](https://app.tigzig.com) - a portal with 30+ micro-apps covering database AI, quants tools, GPTs, automations. Right now building a 20-user internal AI tool with React + PHP backend. Pre-AI coders, I couldn't have done this.

I use Claude Code as primary, Cursor as backup, Gemini CLI when I don't need the heavy lifting.

## But isn't that a developer's job?

I have spent over 25 years doing models, automations, dashboards. My world used to be SAS, Python, SQL, Power BI. That time is gone. You don't have that luxury anymore.

## Where to start

Pay $20/month for Cursor or Claude Code. From your pocket if needed.

Want to test free first? Google Antigravity ([antigravity.google](https://antigravity.google)) has Gemini 3 Pro + Claude Sonnet 4.5 on free tier. Then move to Cursor or Claude Code. Add in Gemini CLI (free) for lighter work. Mito AI for notebooks.
