The CelerFlow browser extension powers browser handoff — the mechanism that lets a BioMed workflow obtain a PDF that sits behind a paywall or institutional login, without CelerFlow ever bypassing the publisher’s access controls.

​
Why it exists

When a BioMed run reaches a paper whose PDF isn’t openly available, the institutional_access_agent creates a handoff session and pauses the run. Rather than scraping around the paywall, CelerFlow asks you to fetch the file in a browser where you’re already authenticated — through your library proxy or institutional login. The capture happens on your authority, in your session.

​
How a handoff works

1

A run pauses

A BioMed workflow hits a paywalled paper and opens a handoff session. The workflow waits.
2

You capture the PDF

With the extension installed, open the paper in your authenticated browser. The extension captures the PDF and sends it back to the workflow.
3

The run resumes

CelerFlow attaches the captured PDF and the workflow continues automatically — on to triage, citation resolution, and Zotero export.

​
Install and configure

Open the Browser extension settings page (/{slug}/settings/extension) for the install link and setup steps. Once installed, the extension links to your workspace so handoff sessions route to the right account.

​
Availability

The browser handoff extension is available on all plans, including Free. The BioMed agents that create handoff sessions, however, require a paid plan — see Billing.
