Calculates with proof
Every engineering result can expose the exact code and output that produced it.
Vasudha / offline engineering assistant
Compute,
don’t guess.
Vasudha is a 4-billion-parameter engineering assistant that runs on your machine — paired with a real Python sandbox, so every number is executed rather than recalled.
Windows 10/11 · ZIP download · no Python, Ollama, or API key required.
Small models hallucinate arithmetic.
The equation can be right.
The answer can still be wrong.
Ask a local model for a beam deflection and it may write the correct formula, substitute the correct values, then miss the result by a factor of ten. That’s because it predicts text. Vasudha gives it a real calculation path.

Your machine.
Your model.
After the one-time model download, Vasudha works without an account, subscription, API key, server, or open port. Its desktop app is a pywebview shell talking to Python through an in-process bridge.
Read the release notes ↗Shows source status honestly
Documents written without opened sources are labelled unverified — enforced by the app, not requested of the model.
Stays editable
Engineer, Teacher, Analyst, and Companion are plain JSON personalities you can change without rebuilding.
The honest bit
Useful doesn’t mean infallible.
Vasudha can still recall a formula with the wrong boundary condition, make magnitude errors, and overreach from thin research. The calculation path is the trustworthy one; research output remains an experimental draft.
