A studio that got tired of re-explaining itself.

How it started

It began with a small, familiar moment. Three hours into a hard problem with an AI assistant, we'd finally worked out the shape of it — the trade-offs, the dead ends, the one odd constraint that made the obvious answer wrong. The next morning the assistant knew none of it. So we explained it again. And again the day after.

The models are brilliant, and they have the memory of a goldfish. The "memory" on offer was a handful of facts on someone else's server. We wanted the tool to actually know our work — and we wanted that knowledge to stay ours, on our own machine. That became Anvil.

Why it exists

Anvil makes the AI you already use more capable: it remembers your projects, learns how you work, applies your rules and personas, and argues through the hard calls before it answers. It adds to what you can do; it doesn't do your job for you. We build tools that act as a mentor, not a ghostwriter.

It's built with the discipline of more than 30 years in systems architecture, security and enterprise infrastructure: local-first, encrypted, auditable, and designed to degrade gracefully instead of breaking.

The name

XrossWarden joins two ideas. Xross is a mark carried for decades — a personal root, the cross at the centre of the work. Warden is the guardian: the one who keeps what matters in custody. Together they say what we do — guard what's yours, and keep it yours: your memory, your rules, your data, on your machine.

What we believe

Your data stays yours. Free tiers should be real tools that get people ahead, not a nag to upgrade. Software should never hold you hostage. And we'd rather ship something honest and useful than something loud.
