Everyone is talking about token spend, but not what we actually spend tokens on. I’ve always found it interesting to track my time across different tasks to challenge whether I was working on the right things.

Nowadays, I spend around 95% of my day in the Claude desktop app, so “where did my time/tokens go?” basically means “what did I do in Claude?”*

Turns out it’s all already on your disk. Every Claude Code / Cowork session is a JSONL transcript with per-message usage blocks: input, output, cache creation, cache read, and timestamps.

Run the snipped below to get an overview of what you did and when based on your Cowork and Claude Code history. Example output:
