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.

Claude - The Universal Agent

Published: March 19, 2026

6 months ago Claude was just an AI coder. Then things changed fast.

Claude in Excel. Claude in PowerPoint. MCP connectors to databases. Desktop app with file access. And Cowork.

And today - the 'dispatch' feature - give instructions from your phone while it works on your laptop.

It went from AI coder to universal agent.

One tool now handles what used to need 5-6 separate tools. Excel formulas, slide decks, PDF reports, internal apps, full-stack builds, security scans, database queries.

Every role uses it differently - CXO to analyst to developer.

The way of working changed. The outcomes got bigger.

How the Work Splits

You bring:

Domain expertise

Judgment

Quality checks

Strategy

Decisions

The AI does:

Coding

Building

Analysis

Deployment

Automation

Human expertise… that’s the differentiator

Feed it gold, you get gold …feed it bull ….

The Impact

The impact is not in percentages. It is in multipliers. It comes from two areas:

1

Faster & Better

What you already do today - done at multiples of the current speed and quality.

2

Entirely New

Things you could not build before - now you can. New capabilities that were not possible earlier.

Each era brought a tool that collapsed weeks of work into hours.

Punch Cards

Programming Languages

Weeks of card-punching - hours of typing

Pen & Calculator

Spreadsheets

One person does what a team of clerks did

Manual Ledgers

Accounting Software

Month-end close: weeks - days

Humans on Computer

AI on Computer

Human builds

Same equation…

Weeks to hours

Human describes. The AI builds.

What Changes for Each Role

Some examples

CXO / Senior Leaders

Before: Describe your vision to the team. Wait for a deck or prototype.

Now: Describe it to Claude. Get a working mock-up in minutes.

Product Manager

Before: Write a spec sheet. Share with design and engineering. Wait.

Now: Share a working prototype. Run competitive research in hours, not weeks.

Developer / Tech Lead

Before: Specialize in frontend or backend. Hand off across the pipeline.

Now: Full pipeline - frontend to server management to security. One person, full stack.

What Changes for Analysts & Data Scientists

The new normal – going beyond analysis, dashboards & ML models

What We Used to Do

Excel analysis – create every pivot & formula by hand, validate manually

SQL, Python – by hand

ML models - code by hand

Dashboards & reports - format and update manually

… and then comes the PPT .. by hand …

then the v2 …v3 …. by hand

The New Normal

Everything above - that's still the foundation. But now you direct and AI does it for you.

Plus:

Internal tools & AI Apps

Fully custom dashboards

Automated workflows

Working prototypes - build it, hand to IT

API - connect systems, pull live data

MCP servers - connect AI agents to analytics outputs and reports

Full-stack apps - React, FastAPI, databases / CI-CD (basic/ internal)

Note : Enterprise Grade Apps are a different ball game
