Bobbin
The missing memory for your AI.
Bobbin privately captures what you browse and read, so your AI assistant knows it too.
Chrome Web Store
What it does
- Remembers readable pages you open, after you press I agree, and keeps that library on this device.
- Lets you search what you read, ask questions with citations, and browse people and companies you looked up.
- Optionally copies the same memory into a Google Drive folder you own, so Claude, ChatGPT, Gemini, and other assistants can read it.
How it works
flowchart LR
A[Browser capture] --> B[Local library on this device]
B -->|optional Assistant Sync| C[Your Google Drive sheet and Pages docs]
C --> D[Assistants read via their Drive connectors]
Indexing, search, and Ask run in the extension. There is no Bobbin server. Assistant Sync is off until you enable it. When it is on, Bobbin writes a spreadsheet and one Google Doc per day into a folder named Bobbin Memory, using the drive.file scope (files Bobbin creates, not the rest of your Drive).
Supported assistants
| Assistant | Plan notes |
|---|
| Claude | Free plan works |
| ChatGPT | Needs a ChatGPT plan with apps |

Privacy
- Capture and search stay on this device.
- Assistant Sync is optional and writes only to your own Google Drive, with
drive.file.
- There are no Bobbin servers and no ads.

Development
Requires Node 20.
npm ci
npm run build
Then open chrome://extensions, turn on Developer mode, choose Load unpacked, and select the dist folder.
npm test # unit tests and eval tests
npm run typecheck
npm run e2e # Playwright (build first)
npm run check:budget
Use npm run build:store only when packaging the Chrome Web Store zip. That build uses the store OAuth client and omits the unpacked key. After a store build, run npm run build again if you still load dist unpacked.
