Working systems lab
Operate a small mechanism, then inspect the larger system behind it.
The first layer below executes real, bounded work in your browser: deterministic extraction, local Canvas processing, pixel inspection, and geometric visibility. The second layer remains an illustrative spatial model. Neither replaces the audited product case.
Working mechanisms
Small enough to inspect. Real enough to operate.
Synthetic inputs keep the surface safe and repeatable. Where a local file can be selected, it is decoded and processed by browser APIs in the current tab. Each mechanism exposes its boundary so a useful interaction is not mistaken for the full product.
Document intelligence
Turn labelled text into reviewable fields with source evidence.
Edit the synthetic invoice, run a narrow deterministic parser, inspect the exact source line behind each field, and record a review decision.
Edit this synthetic invoice or paste similarly labelled text.
No upload or network request is used by this mechanism.

]Claim boundary. This is a real browser-side parser for a constrained invoice pattern. It is not the MetaExtract model stack, OCR layer, table parser, or production evaluation system.
Inspect the MetaExtract caseIllustrative spatial explainer
Inspect simplified product loops, then verify the real case study.
Switch systems and operating views inside the Three.js layer. Its controls are functional and its geometry is illustrative; current maturity and shipped capability remain defined by the case pages.
The HTML controls are functional and the Three.js scenes are interactive, but the geometry is illustrative. Product maturity and shipped capabilities are defined only on the linked case-study pages.
Audited case studies
The mechanism opens the conversation. The case study remains the source of truth.
SignKit
A desktop workflow for extracting handwritten signature images, cleaning them, and placing them into PDFs without requiring sensitive files to be uploaded to a server.
MetaExtract
A structured workspace for inspecting files and documents, extracting high-coverage metadata, and keeping outputs reviewable instead of hiding them behind one opaque model response.
EchoPanel
A macOS recording and transcript workflow designed around local capture, private processing, and finding the exact moment later.
SentinelTwin
A physical-security digital twin for camera planning, coverage analysis, incident paths, comparison, and evidence-backed hardening decisions.
