Token consumption is the new lines of code.

In 2024, we measured developer productivity by commits, PRs, and velocity points. None of that captures how much a developer actually leverages AI. Jensen Huang said it publicly: the developers who consume the most tokens are the most productive. They ship faster, iterate more, and build what used to take teams of 10.

But right now, there's no way to measure this. Your AI spend is scattered across Anthropic, OpenAI, Google, subscriptions, API keys, local tools. Nobody has a single number. Jensen Monitor gives you that number. Not to limit your spending — to make sure you're spending enough.

In the near future, CTOs will track their team's token consumption like they track velocity today. The highest consumers will be the highest performers. The engineers spending the least on AI will be the ones falling behind. A low Jensen Score isn't a badge of frugality — it's a red flag.

A low Jensen Score doesn't mean you're saving money. It means you're underinvesting in the most powerful lever you have. Spend more. Ship more. That's the game now.

How data flows in.

Three methods. No cloud. Everything stays on your Mac.

API: Auto-fetched

Anthropic and OpenAI billing APIs. Read-only keys. Jensen Monitor calls their /usage endpoints and pulls your token spend. No write access. No conversation data.

Endpoints: api.anthropic.com, api.openai.com

Subscriptions: Manual

Claude Pro ($20), ChatGPT Plus ($20), Gemini Advanced ($22), Cursor, Copilot — enter once, tracked monthly. Edit anytime if plans change.

You enter. We remember. That's it.

Claude Code: Local logs

Parses Claude Code's local log files on your Mac to estimate token usage. No API key needed. No network calls. Pure filesystem read.

Reads ~/.claude/ logs locally

Zero-cloud architecture

API keys stored in macOS Keychain (AES-256 encryption managed by Apple). No server. No accounts. No telemetry. No analytics in the app.

One metric. Your definition.

Jensen Score = (Subs + Tokens) YTD / (Salary × Budget%)

Set your annual salary and how much you want to allocate to AI tools. Jensen Monitor computes your score automatically. A developer making $120K who allocates 5% has a $6K annual AI budget. If they've spent $2,700 by June, their Jensen Score is 45%.

I've been building tech and retail products for 25 years. Last year, I went all-in on AI for development — Claude, OpenAI, Gemini, Claude Code. My workflow changed completely. Then I looked at my invoices: several hundred euros per month across 4 providers. But here's the thing: I wasn't spending enough. My Jensen Score was low. I wasn't leveraging AI as much as I could.

Jensen Huang said it: token consumption is the new measure of developer productivity. I believe that. So I built a tool to track it — not to cut costs, to make sure I'm investing enough. Jensen Monitor is v1.0. I'm the first user. If you're an AI-native developer who wants to know their number, try it. If you have feedback, email me directly.
