What it could do

Screenshots from the shipped extension.

Inbox triage through the Gmail API rather than screen-scraping, with each tool call and its arguments visible as it ran.

Two app-specific agents in one conversation: a YouTube transcript read, then rows appended to a Sheet by the Sheets agent.

Four open tabs, a video transcript and an article attached as explicit context for a single answer.

Web Explorer answering against live resale listings, from the product page, in the side panel.

Why it stopped

SurfBuddy ran agents inside the browser against real accounts — Gmail, Sheets, Docs, Calendar, the open web. Building it meant writing the same layer over and over: the schema for each tool, the auth, the wire format, the rules about what a model was allowed to see and send.

That layer turned out to be the interesting part, and the part nobody had built openly. So I stopped building the product on top of it and started building the layer itself.

It's called Charter. It's open source, Apache-2.0, and it runs in your process.
