rabbitholes sends your highlights straight to Anthropic — no server in between

Most browser extensions that call an AI API route traffic through the developer's server. That means every sentence you highlight, every concept you look up, every follow-up question you type passes through infrastructure you don't control, gets logged or not logged at someone else's discretion, and lives in a database somewhere until it doesn't. rabbitholes doesn't work that way. When you highlight a word and the tooltip fires, the request goes from your browser directly to api.anthropic.com .
