About

Ever wonder what you actually did online last week? Or what you were obsessed with three months ago? rabbithole turns your browsing history into a readable, honest summary of how you've been spending your time on the internet.

What It Does
Pick any week — this week, a random one, or any week from your history using the built-in calendar — and rabbithole analyzes your visited pages using AI to surface:

A plain-english narrative of what you were focused on that week
The topics you kept coming back to
Behavioral insights and patterns you might not have noticed yourself
Your most visited sites
Sites you'd never been to before that week — the true rabbit holes

Why Install It
Most people have no idea what they actually spend time on online. rabbithole gives you that clarity without any tracking, dashboards, or ongoing data collection. It reads history you already have, runs the analysis on demand, and shows you something genuinely interesting about yourself.
It's useful for reflection, curiosity, or just satisfying the nagging feeling that you spent way too much time on one particular corner of the internet last Tuesday.

Privacy
Your browsing history never leaves your device except for the page titles and domain names sent to the AI model of your choice (Anthropic or OpenAI) to generate the summary. Your API key is stored locally in Chrome and never transmitted anywhere else. There are no accounts, no servers, no data retention.

Bring Your Own Key
rabbithole requires an Anthropic or OpenAI API key. It defaults to Claude Haiku, which costs fractions of a cent per analysis. A $5 credit covers thousands of summaries.
