Free side project · AU prices
A free tool I built for Australians who want a PC but find the research exhausting. Tell Advisor Sab your budget and what you want to play — she'll handle the rest. Takes about 2 minutes.
No account needed · No ads · Prices pulled from AU retailers
Two main tools, both free, no account needed.
An AI advisor that knows AU pricing. Tell her your budget and what you play — she'll build a parts list, explain every choice, and answer follow-up questions in plain English.
Open Sab →Not sure where to start? Answer 5 quick questions — budget, games, resolution, extras — and get a complete build recommendation sent straight to Sab.
Start guide →Compare two builds side by side — price, FPS estimates, power draw, and value score. Useful when deciding between two GPUs or budget tiers.
Compare builds →Once you have a build, tick off parts as you buy them. Sab tracks what you've spent and what's left — useful if you're buying across multiple paydays.
Open planner →Sab is an AI that's been given all the context a good PC-building friend would have — AU pricing, compatibility rules, current hardware rankings, and the ability to explain things without jargon.
A few things worth knowing before you rely on this.
BuildFX is something I built because I kept seeing friends overpay for PC parts or buy incompatible components. There's no company behind it, no investor, no monetisation plan. It's free and will stay free.
Sab uses web search to check current AU prices but she's not connected to live inventory. Always verify the final price at the retailer before buying — prices change daily.
She's an AI. She knows a lot about PC hardware but she can make mistakes, especially on very new or niche components. Use her as a starting point and a second opinion, not a final word.
