Right on the page

Everything your staff needs, without leaving the workpaper.

The extension is a delivery surface for Quality Companion: the same firm-grounded quality guidance, delivered as a sidebar inside the engagement platform your teams work in every day.

Ask, right where you work

Staff ask questions and get cited answers from a sidebar inside the engagement platform — no new tabs, no new logins.

Methodology while they work

Your firm's methodology, approved sources, and prior engagement context surfaced right where staff are working — so they learn your process while they execute.

Real-time quality feedback

Quality review as work happens. Methodology gaps, missing documentation, and sampling issues are flagged before partner review — when they're cheapest to fix.

Enforcement, not just guidance

When your methodology requires a three-way match and step two is skipped, it's flagged immediately — a quality gate during the engagement, not after.

Works with your cloud stack

Works with all major cloud engagement platforms, with custom integrations for your firm's stack.

Value on day one

Install the extension and Quality Companion shows up in the platform your teams already use — nothing new to learn, no rollout friction.
