An AI assistant that says when it doesn’t know.

If your library doesn’t cover a question, Chairlift says so instead of guessing.

Example from the Process Safety Library

Question: What’s the safe operating limit for our reactor R-101?

“I can only answer from the Process Safety Library materials, and they don’t cover that.”

R-101’s limits live in your own process safety information. The standard says where:

Reactor R-101Harrow Bend Chemical
Your PSISafe upper and lower limits1910.119(d)(2)(i)(D)
Operating procedureOperating limits1910.119(f)(1)(ii)

3 tiers searched0 passages on R-101
Rule P-02Plant-specific value
0 numbers madeRefuse and redirect

Examples are built on public documents; access tiers are simulated.

A confident wrong answer is worse than none.

Members ask for values that belong to their own plant, aircraft or patient. A general AI tool will produce a number anyway. In safety and compliance work, that is a liability.

How Chairlift handles it

Chairlift answers only from the documents a person can access.
When those documents don’t cover the question, it declines in plain words and points to the right source.
Every decline is counted, so your team can see what members ask for.

The rules are yours.

Your team writes them in plain words. Each one shows how often it fired.
