PENKRA APPS

Apps make agents useful for your work.

Each App can add an interface you use, capabilities your agents call, and skills that teach them how. Start with Files + Editor and Browser, then install more.

WORK IN PARALLEL

Run tasks in parallel—not one by one.

Each thread runs independently. See what’s working, what needs approval, and what’s done—without opening every conversation.

ONE WORKSPACE

Files, browser, and conversations—together.

Open a file, check a page, and talk to an agent side by side. Everything stays attached to the thread where the work belongs.

PERMISSIONED BY DESIGN

Apps only see what you hand them.

An App cannot browse your conversations, folders, settings, or other Apps. It gets only the input an agent passes and the permissions you approve.
