Property buying is rigged
- politely.
The listing is marketing. The price guide is strategy. The agent is legally bound to the seller. Buyers make the biggest financial decision of their lives with the least professional support in the transaction. keysz levels the table.
The seller pays for expertise. You get a brochure.
Agents, stylists, copywriters, auctioneers - all working for the other side of your biggest purchase.
Portals show you listings, not answers.
Estimates that disagree by $400k, no risk flags, no ownership costs, no negotiation help.
keysz works only for the buyer.
No seller commissions, no advertising from agents, disclosed referral fees. Your data is never sold to the selling side.
Everything the listing doesn't tell you.
One workspace that accumulates evidence, pricing logic, risks and negotiation strategy for every property you're considering.
Research any property
Paste an address or listing URL - on-market, off-market or private sale. keysz builds a structured buyer file and flags what's missing.
Evidence-based price guidance
Comparable sales normalised for land, condition, parking and heritage - with confidence levels, not one magic number.
Risk & planning scan
Heritage overlays, flood and bushfire zones, easements, title prompts and where a professional report is worth ordering.
Due diligence in one place
Order building & pest reports, upload the Section 32, attach inspection photos - everything lives against the property.
Agent strategy coach
Paste agent messages and get the questions to ask, evidence to challenge price claims and offer sequencing that protects you.
Buyer-fit scoring
Every property scored against your actual brief - budget, commute, schools, parking, renovation appetite and deal-breakers.
A real property, researched end-to-end.
66 Motherwell Street, South Yarra - six screens showing how a property moves from “interesting” to a defensible purchase decision.







From “maybe” to “we bought it.”
AI does the repetitive research. Humans step in where judgement and licensing matter. One buyer record the whole way through.
Build your buyer brief
Budget, finance, suburbs, commute, schools, renovation appetite and hard deal-breakers - captured once, applied everywhere.
Add any property
Enter an address or paste a listing URL. keysz creates the property file and identifies what still needs investigating.
Investigate with AI
Price evidence, planning overlays, ownership costs, transport, parking and document review - done in minutes, not weekends.
Decide & negotiate
Set a walk-away number, compare your shortlist, ask sharper questions - and bring in a licensed advocate when it gets serious.

Not another estimate. An argument you can act on.
Portal estimates for our worked example disagree by $400,000. A keysz report shows the comparable sales, what was normalised, what's verified versus modelled - and the questions to ask before you offer.
Verified - title details, rates, planning records, inspection reports
Observed - your photos, measurements and agent statements
Estimated - modelled ranges with confidence labels, never false certainty
Free AI. Pay only when real work needs doing.
No subscription treadmill. The AI workspace is free - you pay at high-value moments, with every fee and referral disclosed.
