# Voice and Language

<Note>
  Eval Labs voice should be direct, calm, precise, and product-serious. It should explain what is true without sounding sterile or overhyped.
</Note>

***

## Voice traits

Eval Labs should sound:

```text theme={"dark"}
direct
calm
clear
serious
warm
inspectable
truthful
```

It should not sound:

```text theme={"dark"}
salesy
generic SaaS
academic sludge
AI hype
vague innovation language
```

***

## Preferred language

Use:

```text theme={"dark"}
human judgment layer
behavioral evaluation
review evidence
quality standard
failure pattern
regression suite
truth-state discipline
operator calm
response contract
```

Avoid:

```text theme={"dark"}
magical AI insights
unlock exponential intelligence
revolutionary automation
next-gen synergy
fully autonomous trust engine
```

***

## Tone rule

Eval Labs can be confident.

It should not be grandiose.

Good:

```text theme={"dark"}
Eval Labs gives us repeatable evidence about whether Lucia is improving.
```

Bad:

```text theme={"dark"}
Eval Labs revolutionizes the entire AI evaluation paradigm forever.
```

***

## Writing pattern

Use this shape often:

```text theme={"dark"}
State the truth.
Name why it matters.
Give the operating rule.
```

Example:

```text theme={"dark"}
Saved suites make evals repeatable.
That matters because Lucia can only improve safely if the same behavior can be tested after each change.
The rule is simple: important prompts should become reusable suites.
```

***

## Eval Labs vs Lucia voice

Lucia voice is operator-facing and emotionally containing.

Eval Labs voice is reviewer-facing and evidence-oriented.

Eval Labs can be a little more technical than Lucia, but it should still preserve calm and clarity.

***

## Language to protect

This phrase is important and should remain part of the Eval Labs identity:

```text theme={"dark"}
Eval Labs is Lucia’s proprietary evaluation platform.
```

This phrase is also useful:

```text theme={"dark"}
Human grading is the product.
```

Use it when explaining why Eval Labs is different from generic benchmark systems.

***

## Employee-facing review language

Employee-facing language should be simple and non-technical.

Prefer:

```text theme={"dark"}
Did Lucia understand what was needed?
Should a senior reviewer look at this?
Could this teach Lucia something reusable?
```

Avoid:

```text theme={"dark"}
Classify operational intent.
Select canonical adjudication labels.
Define action taxonomy.
```

The UI should invite honest judgment, not performative expertise.
