What BrainyCalc does

Instead of having an LLM estimate mathematical or scientific answers, the AI sends the computation to BrainyCalc, which handles the heavy lifting with precision and verification.

This enables AI systems to move beyond approximate reasoning when accuracy, transparency, and reproducibility are essential.

Compute

Reliable numerical or symbolic methods. No estimation.

Verify

Independent second pass catches instabilities before they reach your agent.

Reproduce

Same input, same output — always. Non-determinism eliminated.

Report confidence

Confidence scores and error bounds with every result.

Record provenance

Engine version, method, and parameters captured.

Audit trail

Fingerprinted and stored — inspect or reproduce any time.

Use cases

Where accuracy isn't optional

Convert anything, between any unit system

Everyday units

From everyday conversions like kg to lbs, to engineering-grade computations across thermodynamics, electrostatics, and radiology — every unit, every system, in one place.

Mathematics & Statistics

Verified mathematical computation

Power scientific calculators, algebra, calculus, linear algebra, probability, statistics, optimization, numerical methods, and thousands of deterministic mathematical computations with independently verified results.

Health & Life Sciences

Medical & longevity calculations

Power BMI, BMR, TDEE, body fat, pregnancy, kidney function (GFR), biological age, life expectancy, healthy lifespan, and disease risk calculators with verified, reproducible scientific computation.

General Utilities

Everyday calculations & conversions

Power date, time, age, unit conversion, fuel cost, electricity, bandwidth, engineering and thousands of everyday utility calculators with accurate, reproducible computation.

Science and research

Scientific pipelines

Computations that hold up to peer review. Full reproducibility — ready to cite.

Engineering

Design calculations

Structural loads, thermodynamics — numbers that can be independently checked and audited.

Compliance and audit

Regulated workflows

Healthcare, legal, financial — computation trails inspectable and reproducible on demand.

Integrate

Model Context Protocol Ready

Connect BrainyCalc directly to agent platforms (e.g., Claude Desktop, LangChain, or custom SDK implementations) through standard JSON-RPC communication protocols.

Standardized Schema

Automatic tool-calling mapping out of the box.

Locally Runnable

Host directly on your cluster infrastructure for lower latency.
