Klorra is an AI takeoff and estimating pipeline for custom home builders. Upload an architectural plan set; get a complete takeoff, line-item cost estimate, scope of work, and conflict report back inside four hours. Below is what each phase actually does — and why we built it that way.
Each phase runs a focused job, hands a structured artifact to the next, and gets re-audited downstream. Click any phase to expand it.
The pipeline is opinionated. Here's what we lock in and why.
Every phase runs on Claude Opus 4.7 — Anthropic's top frontier model. No budget-tier substitutions on the takeoff and pricing phases, no smaller models cutting corners. The same caliber of reasoning reads your plans, runs the takeoff, prices the cost codes, and audits the result.
When the agent adjusts a unit rate above or below the regional baseline, the adjustment is captured with a reason — and re-audited in Phase 5 by a second pass that doesn't see Phase 4's reasoning. Plausible-looking errors are exactly the failure mode we're built to catch.
A working builder spot-checks every bid before delivery during the early months. The AI is doing the work; the human is the final sign-off — same as any senior estimator would do for a junior's output. We're not hiding the loop. We're also not pretending the AI ships unsupervised.
Klorra deliverables are budgeting and planning tools, not warranted bids. Every quantity and rate is the builder's responsibility to verify before commercial use. Terms §3.2.
