Why it holds up
Separation of powers, grounded in the sources.
Separation of powers
The drafter is never the reviewer
Four independent stages, each bound to a different provider. The stage that writes your response never gets to clear it.

The moat
A hostile reader that has read the playbook
Your draft is read the way a hostile employer will — grounded in an evidence-graded corpus of documented Australian employer practice.
How it’s grounded →
The floor
Grounded in the primary sources
Legal references are checked against integrity-sealed authority packs. When nothing matches at high confidence, the system says so.
How it’s grounded →
Quadratic does not detect AI-written or ‘inauthentic’ documents, and never will. It simulates how a hostile reader could attack your document — it never adjudicates who wrote it.
Quadratic prepares your written response to a PIP, show-cause letter or allegation. Before it reaches you, every claim is checked against the Fair Work Act, the draft is read the way a hostile employer would read it, and a final independent stage decides whether it’s ready — if a check can’t be completed, it’s held back, not guessed.
The system, working
Watch a response get produced.Every document goes through this sequence before it reaches you.
Situations we handle
Built for the letter in front of you.
Situation
PIP response
A performance improvement plan questions your work in writing. Your reply shapes everything that follows.
Response windows are often short — sometimes days.
Situation
Show-cause response
A show-cause letter asks why your employment should continue. Each stated reason needs an answer.
Deadlines are usually fixed, and close.
Situation
Allegation or investigation response
An allegation letter asks for your version of events, in writing. What you write becomes part of the record.
You are often asked to respond before a meeting.
Checks and balances
One model can sound confident and be wrong.So no single check decides your response is ready.
“The part that writes your response never gets to clear it.”
The Fair Work Commission has flagged a rise in AI-assisted submissions that “look professional but are fundamentally flawed.” Quadratic is built so yours isn’t one of them.
- 01
Draft
Your response is written for you, answering every concern in the letter.
- 02
Check
A separate stage verifies each legal claim against the Fair Work Act — weak or unsupported references are corrected.
- 03
Hostile read
Another stage reads it the way your employer would, looking for anything that could be turned against you.
- 04
Rule
A final stage decides on release. If a single check can’t be completed, the document is held back — not guessed.
Several independent checks, not one. If one misses something, the next is built to catch it — and the part that writes your response is never the part that clears it.
It’s built to push back on your draft, not flatter it. How the checks are kept independent is deliberately not published — that independence is the product.
How that independence works is proprietary. More detail, in plain language
Pricing
Free during the private pilot.
$199AUD per document, at launch
One flat price for the whole job — drafting, verification against the Fair Work Act, an independent review, and a finished document you can download. No tiers. No subscription. No hidden costs.
Full document generation on your own matter is in invited pilot while pricing is finalised.
The boundary
This is not legal advice.It’s a tool to help you write a stronger response.
Quadratic helps you put your own position in writing. It doesn’t represent you, and it doesn’t replace free, independent help. The Fair Work Commission’s Workplace Advice Service offers free legal assistance to eligible workers, and the Fair Work Ombudsman explains your workplace rights.
If things feel like too much right now, Lifeline is available any time on 13 11 14.
From the founder
Quadratic is designed, built and operated in Melbourne. I started it because the moment a letter lands, the employer has a process and the worker has a deadline. The system is live and in private pilot now. If it would help you, get in touch — you’ll be dealing with a person, not a funnel.
