The smartest HammerHand you'll ever hire.
Take your AI offsider to site. Talk as you work and it does the writing — Healthy Homes and pre-purchase reports, compliance certs, hours, materials and the client handover — offline, in your pocket. And everything you capture is verified and locked: a defensible record that holds up if it's ever questioned. One app that fits your trade — your AI offsider on the job, handling everything off the tools so you stay on them and keep every call.
Your HammerHand for the month — from $75 +GST. Register your interest to lock in early-access pricing.
✨ Voice to report
You talk. HammerHand does the typing.
This is the part that gives you your evenings back. Say what you see on site — "bathroom extractor's only 100 mil and it vents into the roof space, not outside" — and HammerHand turns it into a structured, drafted finding: a clean description, a suggested severity, the right outcome, in the report's language. The AI does the writing; you keep the judgement.
- Speak on site — hands free, gloves on, no signal needed
- The AI drafts the finding; you edit, set severity, and confirm
- Your original voice note is kept, so every finding traces to exactly what you said
- Nothing reaches the report until you verify it — you hold the authority
How it works
Three steps, one field visit
The whole loop is built around one idea: the AI does the typing, and you keep the authority.
Walk & talk
Move through the property area by area. Speak your observations and snap photos — it all saves on your device, even with no signal.
Verify the draft
HammerHand turns each voice note and photo into a structured, drafted finding. You review, edit, set severity, and confirm. Nothing enters the report until you say so.
Send the report
Compile a branded, dated report with your findings, evidence and embedded disclaimers — then deliver it to your client. Same day.
Why HammerHand
Made for the way inspections actually happen
Crawlspaces, wind, gloves, no signal — and a report that has to stand up if it's ever questioned.
Voice-first capture
Describe what you see out loud instead of typing on a phone in a subfloor. HammerHand structures it for you.
Offline, nothing lost
Capture works fully offline against on-device storage and syncs when you're back in range. A lost finding is a lost inspection — so we don't lose them.
AI drafts, you verify
Every AI suggestion is a proposal. It only becomes part of the report when a human confirms it — the core of a defensible document.
Healthy Homes & pre-purchase
Configurable, versioned templates: a Healthy Homes assessment today, a pre-purchase NZS 4306 report next — one engine, not hard-coded.
Evidence & audit trail
Every finding traces to its photo, voice note, the template version, and your sign-off — kept for the years an inspector works to.
Disclaimers travel with it
Scope, limitations and disclaimers are embedded in the report itself, and a published report is locked — later edits make a new version.
Healthy Homes
Numeric pass/fail, done properly
Run the five Healthy Homes standards with the heating-capacity and insulation helpers doing the maths — deterministic pass/fail on the values you actually measure, never a guess.
- Heating, insulation, ventilation, moisture & drainage, draught stopping
- "Insufficient evidence — further investigation" is a valid, honest outcome
- Condition, severity and maintenance priority kept as separate concepts
Pre-purchase
NZS 4306 builder's reports — on the same engine
Because report types are versioned data, adding the pre-purchase builder's report doesn't mean a second app. Same capture, same verify, same defensible output — a different template.
- Site, subfloor, exterior, roof, interior, services and moisture
- A configurable defect library tuned to NZ housing stock
- New-build and pre-sale reports to follow
More than inspections
HammerHand runs your build day, too
The same offline app that writes your reports also helps you run the job — one tool on site, not three.
Log staff hours
Tap out each person's hours on site, day by day. Saved offline and ready when you run payroll or invoice — no more scraps of paper in the ute.
Daily task lists
Speak the day's jobs each morning — or type them — and tick them off as you go. Anything unfinished rolls to tomorrow automatically, so nothing slips.
Build progress record
Photograph framing, services and each stage before it's covered — time- and location-stamped. The record you can't recapture later.
Certificates, ready for CCC
Capture every compliance document as it's issued — records of work, energy certs, producer statements, warranties. A live checklist shows what's still needed for your Code Compliance Certificate.
Hand over a complete pack
At the end, send the client one tidy pack — every stage photo and compliance document, by a secure link. Your hours, wages and costs stay private.
One app, every trade
Pick your trade — the app becomes yours
On first run you choose what you do: inspector, builder, electrician, plumber/gasfitter, painter or scaffolder. HammerHand shows the right tools and the right compliance documents. Same offline capture, provenance and sync engine underneath — one app, not six.
Inspectors
Healthy Homes and pre-purchase NZS 4306 reports — voice-first, deterministic pass/fail, defensible.
Builders
Staff hours, daily tasks and a stage-by-stage build progress record, ready for your CCC.
Electricians
The same job tools plus electrical certification — Certificate of Compliance, ESC and Record of Inspection.
Plumbers & gasfitters
Job tools plus gas & plumbing compliance — Gasfitting CoC, Gas Safety Certificate, Record of Work and Producer Statements.
Painters
The same job tools, billing and record — plus a photo-backed job completion & workmanship record for the client. (Painting's unlicensed in NZ, so no faked certificate — an honest record instead.)
Roofers
Job tools plus weathertightness records — the LBP Record of Work, producer statements and E2 compliance for the roof, to the NZ Metal Roofing Code of Practice.
Scaffolders
Job tools plus a Scaffold Handover Certificate and 7-day inspection records — built to AS/NZS 1576 and WorkSafe guidance, with reminders for the weekly re-inspection.
Record the job as you go
For each problem, dictate what it is and photograph it — tap once to start, tap to finish. Every entry is time- and GPS-stamped for the client.
Certificates that fill themselves
Your address, registration, the date — and your signature — flow onto every certificate from the job and your profile. Sign once at setup; you review and tap issue, no retyping.
Materials, marked up
Log what you fit by voice, camera or text at your buy cost. Your markup turns it into the client charge — your cost stays private.
Invoice, built for you
Labour comes from your staff log and materials from your cost list — each with your markup — plus travel and GST. Bill a whole job or claim by stage on a long one; each invoice is numbered, dated and locked, straight into the client's handover pack.
