About Pensl

We're Blue Monkeys GmbH, a web agency based in Vienna, Austria. We built Pensl because we were tired of chasing client feedback across WhatsApp messages, Loom videos, and vague emails.

We wanted a tool that lets clients point at exactly what they mean — and then have AI fix it. So we built one.

Pensl is self-hosted, open to inspection, and built for the kind of agency work we do every day: staging reviews, text changes, button labels, layout tweaks.
