DoppelBrain remembers everything you read online. Open its side panel on any page and ask in your own words. It can even suggest what to read or where to go next, based on your interests.
DoppelBrain is a personal memory built from your browsing and AI chats. A lightweight Chrome extension remembers what you read, and your AI assistants connect via the Model Context Protocol (MCP) so every model already has your context.Takes 2 minutes. No credit card. Works inChrome.
Works with the AI you already use
Set it up once. DoppelBrain does the rest.
Add DoppelBrain to Chrome, then pin it. The brain sits in your toolbar, one click away on any page you read.
DoppelBrainDoppelBrain quietly remembers the articles and pages you read. The little chip shows it working, and you never have to file a thing.
DoppelBrainAsk about this page…or anything you've read.
Open the side panel and just ask, any language works. Answers come from the page you're on and everything you've read, with the source attached.
DoppelBrainActive recall is about pulling the answer out of your head. Spaced repetition is about when you do it. You read both, three weeks apart.
Flip the extension on and connect it once. From then on, DoppelBrain quietly remembers the pages you read. You never open it or click anything, and the side panel is one click away whenever you want to ask.
Banking, health, and other private sites sit on a constantly updated blocklist. The moment you land on one, DoppelBrain switches itself off. Nothing is read, nothing is stored, and you can't even leave it on by accident.
Type your question into ChatGPT, Claude, or Gemini exactly like before. Behind the scenes, DoppelBrain hands them the parts of your reading that matter, and they weave it into the answer.
ChatGPT, Claude, Gemini. Connect them all at once. They draw from the same DoppelBrain, so the context you built up in one AI carries over to the next.
ChatGPT only remembers chats with ChatGPT. Gemini only remembers Gemini. Neither knows what you actually read. DoppelBrain remembers what you read, and shares it across every AI you connect.
Each AI only remembers chats with itself. Your browsing is invisible.
