Best used with an AI agent

40+ live apps, open data APIs, MCP servers, and 200+ guides - more than anyone wants to click through. Point your AI here and it reads the whole map and does the work: finds the tool, pulls the data, runs the analysis, and hands you the links.

Here for the open-source code? Your agent finds the right repo for you - and can even clone and deploy it.

Prefer to explore on your own? Go right ahead.

Paste this to Claude Code, Codex, or any AI agent:
Go to tigzig.com and read tigzig.com/llms.txt. It is a practitioner toolkit - 40+ analytics apps, open no-auth data APIs, MCP servers, open-source repos (github.com/amararun), and 200+ build guides. Help me [your task]. Surface the exact links; where there is an API or MCP, call it directly; and if I want to self-host, find the repo and help me deploy it.

Build Full Campaign in Excel with Python , xlwings Lite & AI

Published: July 23, 2025

I've released a new field guide covering full campaign build with Python in Excel with AI (xlwings Lite)

Campaigns are where analysis and models face reality, and the results are hard numbers. Years doing this, but each campaign still feels like an exam. A successful one is a relief. A list error? First, the heart goes cold. Then comes the gut punch.

This guide isn't just about building a campaign; it's about the process for working with AI to do it reliably. The guide covers:

The core of this methodology is my personal AI Coder file -1,855-lines of xlwings Lite coding guidelines for AI, updated based on recent client projects. It's the same process I used recently to set up a full outbound campaign for an SMB client on xlwings Lite - from waterfall to final list cut.This work builds on the powerful xlwings Lite toolkit from Felix Zumstein
