LUCID · Thinking Layer for AI

The question you should have asked, before you press send.

LUCID pressure-tests your prompt before it goes to the AI and reviews the answer after it comes back, against the professional Standard you define. It runs inside Claude, ChatGPT, Gemini and Grok, as a Chrome extension.

Your prompt Our churn rose from 3% to 5% after the price increase. Should we reverse the price increase?
PRESSURE TEST
Stated
Whether to reverse a price increase after churn rose two points.
Implied
Protect revenue without giving back the price gain.
Unstated
That the price increase caused the churn. Nothing in the prompt establishes it.
Pressure Test
What else changed in the same period, and what does the revenue look like at 5% churn with the higher price versus 3% churn without it?

The problem

The AI answers the question you typed. Your work depends on the one you meant.

A model takes a prompt at face value. It fills the gaps silently, answers with confidence it has not earned, and pads the reply until the judgment is buried. In casual use that costs nothing. In a clinic, a courtroom, a boardroom or a lab, it is how a wrong premise becomes a decision.

LUCID stands between you and the send button. It reads what you stated, what you implied and what you left unstated, and it puts one hard question in front of you before the prompt leaves. When the answer returns, it reads that too, and flags hedging, flattery and padding, and any line that breaks the Standard you set.

LUCID does not write for you and does not answer for you. It makes you the better thinker in the exchange, and it keeps the AI honest to your profession.

How it works

Before the send. After the answer. Every turn.

01 · BEFORE

The Pressure Test

You write your prompt as usual. Before it goes, LUCID maps what you stated, what you implied and what you assumed, scores how much the AI would have to guess, and asks the one question that challenges all three. You send as is, revise, or skip.

02 · AFTER

The Guardian

When the answer arrives, LUCID reads it against your Standard. Hedging that hides judgment, padding that displaces the answer, false confidence, an assumption inserted without disclosure: each is named inline, under the reply, with the line of your Standard it broke.

03 · ALWAYS

Your Standard

Five questions form your professional Standard once: what LUCID protects, which AI mistakes are dangerous in your work, what makes an answer usable, what must never cross into your professional reality, and what you use AI for. Every test and every review is calibrated to it.

The sidebar

Eight controls. One thin panel beside the chat.

◎

Clarity Score

How much the AI must assume to answer your prompt. CLEAR assumes little or nothing. PARTIAL fills some gaps. VAGUE means the AI invents the missing frame.

⊕

Logical Profiler

Maps the structure of your prompt: what you said, what you meant, what you assumed, and the question that challenges all three.

◈

Response Guardian

Scans the AI's reply for hedging, sycophancy and Standard violations. Flags appear inline below the response, each tied to the rule it broke.

✦

Your Standard

The synthesized voice LUCID uses to calibrate every Pressure Test. View it, edit it line by line, or form it again.

⛨

Deep Guard

When on, LUCID covers a failed answer with the Guardian's verdict and the fixes it needs, and offers to ask the AI to revise it.

≡

Standing Orders

Rules LUCID adds to the front of every prompt. Write them once, and the AI honors them every turn.

↷

Sticky Skip

Keeps the Skip Next chip armed across sends until you click it off, for the stretches when you want the AI unguarded.

⏻

Master switch

Off means off: LUCID stops capturing prompts and the Pressure Test bar does not appear. The sidebar stays open for reading earlier analyses.

Your Standard

Not a setting. A professional document, written in your voice.

LUCID asks five questions and writes your Standard from the answers. It is the document every Pressure Test and every Guardian review is measured against, and it is yours to edit. Pro users see which line of their Standard produced each Pressure Test.

Professional Standard · Executive
01Name the assumption under every recommendation. A recommendation without its assumption is not usable.
02Never present correlation as causation. If the causal link is not established, say so before the advice.
03Quantify risk. "Significant" and "material" are not numbers.
04Dense and direct: the judgment first, the padding never.
05A reversible decision is not framed as irreversible, and the reverse.
