Juniper exists because AI tools for Chrome should be auditable by the people who install them.

Why now

AI-capable browser extensions are proliferating fast, and most declare overbroad permissions with no public accounting of what data they handle.

The problem

Developers who want AI help in Chrome must install extensions that declare broad host permissions and never disclose what leaves the browser. Every research session is a trust gamble: tab content and browsing history handed to a closed-source binary with no auditability and no data manifest.

Our approach

Juniper is an open-source Chrome extension with a published data manifest — audit it before you install it.

Sider and HARPA are closed-source with opaque data handling and broad permissions granted by default. Juniper publishes its data manifest and requests the narrowest permission scope Chrome allows — auditability is the wedge.

Who builds this

Built by developers who have uninstalled one too many opaque extensions.
