Parcelith
TECHNOLOGY

An architecture built for verifiable answers.

Parcelith combines a geospatial computation stack, numerical optimization, and a multi-agent AI council — with a provenance system that ties every surfaced claim back to its source.

MULTI-AGENT ARCHITECTURE

The Development Council.

Specialist agents across multiple model providers analyze independently. Verification tools and critic agents challenge every conclusion. A judge reconciles the evidence.

TOOLS
  • · Geospatial computation (PostGIS / GDAL)
  • · Code & document retrieval with citations
  • · Numerical solvers (OR-Tools / SciPy)
  • · Deterministic rule checkers
CRITIC AGENTS
  • · Assumption auditing
  • · Cross-agent challenge
  • · Source & citation verification
  • · Constraint violation detection
Adjudication
CONSENSUS / JUDGE
A judge agent reconciles specialist findings, weighs verified evidence over unsupported claims, and records dissent.
RECOMMENDATION
An evidence-backed development recommendation — every claim traceable to a source, a tool, or a named agent.
OpenAI, Anthropic, Google, xAI, Local Models providers feed Planning, Civil, Environmental, Zoning, Finance, Market, Construction specialist agents; verification tools and critic agents check the work; a consensus judge reconciles findings into a recommendation.
PROVENANCE

Every claim carries its source.

AI output in Parcelith is not a black box. Claims extracted from documents, codes, or analyses are stored with their source, locator and confidence — and the UI refuses to let an unsourced number look authoritative.

ENGINEERING POSITION

Built to support licensed professionals — never to replace them.

Parcelith accelerates exploration, preliminary analysis and verification support. Certification, legal boundaries and stamped work remain with licensed engineers and surveyors — by design.

Parcelith supports licensed professionals. It does not replace engineers, surveyors, or any professional certification.
