GDBS is one engine running 170 deterministic, citation-backed tools across legal, senior care, finance, pharma, RF, construction, compliance, and scientific computing. Each runs in your browser with nothing uploaded, and every result carries a trust verdict you can re-run and check.
Deterministic, citation-backed legal tools that run entirely in your browser: case-law search against the Supreme Court index and CourtListener (keyless, no AI), regulatory watch over the Federal Register, court-deadline and statute-of-limitations calculators, a drafting toolkit, litigation utilities, and evidence custody with SHA-256 chain-of-custody logging. Every result cites the rule it applied, and nothing is uploaded.

Built for elder-law attorneys, senior financial planners, and skilled-nursing and assisted-living administrators. Statutory math for Medicaid look-back penalties and spend-down, Medicare IRMAA surcharges and SNF benefit periods, PDPM per-diem rates, HPPD staffing compliance, HECM reverse-mortgage limits, and VA Aid and Attendance, each keyed to the CFR sections it uses. Everything runs client-side, so no protected health information leaves the browser.

Transparent, deterministic financial math with no black box and no hidden rounding: option pricing with full Greeks, bond duration and convexity, IRR and NPV with a solver trail, private-equity waterfalls exact to the penny, real-estate underwriting, and a full stack of tax, payroll, and HR-compliance calculators keyed to their IRC and CFR sections. Loan amortization carries a GeoNum precision audit that shows exactly where naive floating-point accumulation stops being trustworthy.

Reproducible, auditable computation for a regulated field: clinical-trial sample size and power, bioequivalence confidence intervals against the FDA window, whole-body PBPK pharmacokinetics, and drug patent and exclusivity timelines, alongside biomedical solvers for cardiac electrophysiology, oxygen transport, bioheat, and tumor growth. Every result is deterministic with a precision trail, which is what an electronic-records compliance context asks for.

Every result carries a wall-time benchmark and a GeoNum trust verdict, with model boundaries stated plainly. Runs on air-gapped and cloud-restricted networks.

The GeoNum Trust Index scores content integrity and produces embeddable, tamper-evident verification badges, so the integrity of a result or a document can be checked independently rather than taken on trust.

The most technically dramatic slice, and the credibility anchor for everything else: numerical relativity, general-relativistic magnetohydrodynamics, a gravitational-wave pipeline, all-electron Kohn-Sham DFT, molecular dynamics, plasma MHD, computational fluid dynamics on CPU and WebGPU, finite-element structures, and more, each checked against an analytic or published benchmark, in the browser as the stage before the cluster.
