Engineering Database docs
Engineering Database is a subscription product for engineers. It pairs 375 structured engineering reference tables with 50+ deterministic calculators, and wraps both in an AI assistant that can look up values and run calculations on your behalf. These docs explain what the product does, how it returns answers, and how usage works.
The guides below are written for engineers, students, and anyone evaluating the product. No software background is needed.
Guides
What EngDatabase AI is
An AI assistant that answers engineering questions from structured reference tables and deterministic calculators, not from model memory.
How Engineering AI works
The four steps an Engineering AI turn goes through, from reading the request to returning a traceable answer.
Architecture overview
The three layers of the product: the reference library, the calculator suite, and the AI assistant that connects them.
How the AI uses structured tables
Why structured reference tables let the AI return exact engineering values, and what happens for interpolated or missing data.
How calculators integrate with the AI
Every calculator in the suite is a tool the AI can run, so sizing, checking, and conversion questions use deterministic math.
How credits and usage work
One credit budget shared across database searches, calculator runs, and AI turns, with daily and monthly caps per plan.
Why this is different from generic LLM chat
A general AI chatbot answers engineering questions from memory. EngDatabase AI answers from tables and calculators.
Supported engineering workflows
Sizing, checking, lookup, and conversion workflows the assistant and calculator suite handle across disciplines.
Limits, assumptions, and validation
What the product does, what it does not do, and how results should be treated in a real engineering workflow.
Start using the product
If you want to try things directly instead of reading about them, the database, calculators, and the AI assistant are all available on the free plan. See pricing for the full plan details.
