Built inside an active custom home builder, opened up to other builders. Upload your plans, get a complete estimate and Scope of Work back the same day. The first one is free — see for yourself.
The whole point is that the AI does the actual work — every bid, end-to-end, in under 4 hours. No human estimator clicking quantities, no offshore takeoff service, no junior estimator learning on your dime.
What makes our AI worth betting on is who built it.
1. It was built inside an active custom home builder — Kaye Lifestyle Homes, Naples FL. The cost-code logic, QC gates, and override discipline all came from years of bidding real jobs. KLH still uses the same pipeline internally on every bid today.
2. It was built specifically for custom homes. Not a generic "AI for construction" tool retrofitted to handle highway work and steel buildings. Not an AI takeoff feature bolted onto remodel software. Custom homes only — that's the entire focus.
Don't take our word for it. Upload your plans. Your first bid is on us — the output is the proof.
Most estimating software is built by software people for software people. Klorra was built by someone who needed it.
I'm a working custom home builder in Naples, FL. Second-generation. Before Klorra, I was personally bidding 40+ jobs a year on top of running active job sites. Every bid took 25–35 hours of senior time, and most of them never became jobs.
So I built an AI workflow internally — a six-phase pipeline that reads plans, runs takeoffs, prices line items, and writes scopes. It works. Over 2025 KLH used it on Labbe, Garcia, Strauss, Conboy, and Schad — five real custom homes, real bids, real outcomes.
Klorra is that workflow, opened up to other custom builders. Not a generic AI startup. A working tool built by someone who needed it, with the cost-code logic and quality control gates of an actual builder baked in.

CMU exterior walls, 8" thick, with rebar reinforcement at corners and openings per code. Stucco finish applied per architectural Sheet A-4.0…
A full takeoff and budget for a 4,000 SF custom home eats 20-40 hours of senior time. Most builders do it on nights and weekends.
Hire one full-time and you can't keep them busy. Hire one part-time and you lose continuity. Most $2-20M builders go without.
Your real cost-per-win is the cost of every bid you produced — including the ones you lost. Most builders never compute this number.
No software to install. No takeoff training. No clicks to count.
Drag in your architectural plan PDF. Answer 12 quick intake questions about lot, finish level, and region. Total time: under five minutes.
A six-phase AI pipeline reads every sheet, runs the takeoff, prices 135 cost codes, and writes the SOW. A senior builder reviews every bid before delivery.
You receive an Excel cost estimate and a client-ready Scope of Work in your inbox, ready to send. One-click revisions if anything needs adjusting.
Move the sliders. The number gets uncomfortable fast.
Most estimates spit out a number. Klorra gives you a budget format that survives the project — built on seven principles we'd defend to any working builder.
Traditional CSI MasterFormat has 16 divisions invented for commercial GCs. We organize by trade — the way subs actually work and the way you actually buy labor. Foundation, masonry, framing, roofing, plumbing, electrical, finishes. Reads like your job site.
Most software conflates takeoff and pricing. We don't. Phase 2 produces verified quantities anchored to specific sheets in your plan set. Phase 4 prices them. The quantities are reusable across price scenarios — change a labor rate and the whole bid recalculates without re-running takeoff.
Every Klorra bid is a Current Budget plus a Budget B alternate. Lets you walk a client through "here's what you're getting at this number; here's what changes at +/-X%." Most estimators give one number; we give two with a clear narrative for the spread.
Every adjustment to a default unit price gets logged with a reason. Look at a Klorra bid six months later (or hand it to a sub) and you can see WHY this number is what it is. Most estimators just type a number — we make the bid auditable.
Every line item references the source on the plan set. No phantom quantities. If you can't trace a number back to a sheet, it doesn't go in the bid. This is the discipline that stops the "Labbe-class" failure mode that punishes builders six months into a job.
Scope changes are first-class. Add a feature, watch the budget delta. Studio tier lets you tweak unit pricing live and see the new total in seconds. Most estimating software treats every revision as a full rebuild — we treat it as the small adjustment it actually is.
Every bid carries its own quality-control findings — within the regional $/SF band? Override audit results? Areas the AI flagged as low-confidence? You see all of it. Most providers hide their uncertainty. We surface it so you know exactly where to spend your senior-estimator review time.
Annual is the default. Monthly available but more expensive — we'd rather have you happy on annual.
Or pay as you go: $799 per bid, no subscription. Your first bid is always free.
Accuracy disclaimer. Klorra deliverables are starting points. We do not warrant accuracy of any takeoff quantity, cost rate, estimate total, or scope language in any specific market or for any specific project. We do not carry Errors & Omissions insurance and do not offer an accuracy guarantee. Every quantity and rate is the builder's responsibility to verify before any commercial use. See Terms §3.2.
The pricing engine is calibrated to Florida, Carolinas, and Texas regional cost data, refreshed quarterly. The takeoff (every SF, every LF, every opening counted) is the most rigorous part of the deliverable — that's what most working builders care about most. The cost layer sitting on top is a regional baseline, not a market-perfect bid. We do not warrant accuracy of any quantity or rate, in any specific market, on any specific project. You verify everything before commercial use. We don't carry E&O insurance and we don't offer an accuracy guarantee — that's by design, and the price reflects it.
Yes. Every step end-to-end: the AI reads the plans, runs the takeoff, prices 135 cost codes, writes the Scope of Work. It then runs three automated QC gates (sanity checks, override audits, total-bid range validation). At the very end a senior builder gives the output a final sanity-pass — that's a safety net, not a bottleneck (it adds minutes, not hours). We're not hiding the human in the loop, but the AI is doing the actual work — the human is there because the AI is delivering bids people will sign contracts on, and that warrants a final sign-off. Same as any senior estimator would do for a junior on their team.
If you spot something the takeoff missed against the plans, click "Request Revision" — corrections are free. The cost layer is a regional baseline, not a market-perfect bid; we don't warrant pricing accuracy on any specific project, and you should verify rates against your subcontractors and suppliers before commercial use. We don't carry E&O insurance and we don't offer an accuracy guarantee. Builders own the final number — that's the model on purpose, and it's why the pricing pencils.
Built by Ben Kaye, VP at Kaye Lifestyle Homes — a working FL custom builder. The cost-code logic, override discipline, and QC checks were developed over years of real bidding inside KLH. Ben spot-checks every bid personally during the early months. This is not a software team that's never read a plan set.
Yes. Plans are stored encrypted, never shared with third parties, used only to produce your bid. We do not train any model on your plans. Aggregated, anonymized cost data may be used to improve regional benchmarks (you can opt out). Your dashboard is private to your organization.
PDF is the standard. We can also work with DWG and DXF on request (Pro tier and above). Scanned plan sets work as long as the text is legible — for very poor scans, we'll let you know and refund the bid.
Those are software you use to do your own takeoff. We do the takeoff for you. They charge you to learn a tool; we deliver a finished bid. If you've ever bought estimating software, opened it twice, and gone back to a paper takeoff — this is for you.
Annual contracts are the default and have a 30-day refund window. Monthly tiers cancel anytime. We'd rather lose a customer who isn't getting value than keep them on a contract they regret.
