About
Sarah Barnbrook
Founder, AI implementation and ethics consultancy
Founder
Sarah Barnbrook has spent a decade working at the intersection of AI governance, digital safety, and technology ethics. Not as an observer, but as a practitioner.
Her work spans international governance processes, original research, policy framework development, and direct advisory engagement with organisations navigating consequential technology decisions. She brings to that work a rare combination: technical literacy, governance experience, and a sustained commitment to the ethical dimensions of implementation that most consultancies treat as secondary.
Xallarap is the commercial entity that houses her intellectual property and brings her methodology to organisations. It is not a firm that arrived at ethics from compliance. It is one that was built from it.
The methodology
Parallax
Belief-reality divergence detection
Parallax is an original assessment framework developed personally by Sarah Barnbrook over a decade of frontline advocacy, international governance work, and original research. It is not a checklist or a compliance tool. It is a belief-reality divergence detection mechanism: it finds the gap between what an organisation believes about its technology and what is actually present, from every vantage point, before deployment or implementation begins.
Without Parallax, Xallarap would be a consultancy offering opinions. With Parallax, it is a consultancy offering a defensible, evidence-based, internationally grounded methodology that can be demonstrated, reproduced, and traced back to source. That is what separates Xallarap from generic AI advisory firms. The technology they use is available to anyone. The intellectual architecture behind the assessment is not.
The name is the principle. Parallax, the apparent shift in position when viewed from a different vantage point, is the engine of the methodology.
The tool
Alt-TAB
Free pre-deployment AI ethics assessment
Alt-TAB is the practical expression of the Parallax methodology: a free-to-use pre-deployment AI ethics assessment tool that screens any technology decision against 35 international governance frameworks simultaneously. Every assessment includes mandatory screening for technology-facilitated gender-based violence, child safety, and cybersecurity, regardless of the technology type.
Free to use
Alt-TAB is available free at alttab.afk.org.au
Alt-TAB is operated by Away from Keyboard (AFK) Inc. under licence from Xallarap. It is free because the public interest case for accessible pre-deployment assessment is clear.
The ecosystem
