Same prompt.
A more useful comparison.

The best model for your scene is a question you can test. Give up to five models the prompt you actually use, then compare their passages with a blind assessment and a closer look at the prose.

How it works

One prompt. Up to five models. Side by side.

  1. 01

    Bring a real prompt

    Use your actual scene, context, and instructions. Tell the lab what you want the writing to accomplish.

  2. 02

    Choose your models

    Select up to five models and review the quote before paying. Each model receives the same prompt.

  3. 03

    Read the evidence

    Compare complete passages, sentence-structure measurements, a blind assessment, and an estimated cost for a novel at each model’s rate.

Built around
the writing.

The writing comes first.

Read the generated passages side by side. You can judge voice, atmosphere, and whether a scene does what you asked.

A blind second opinion.

The assessment sees labeled passages without the model names, reducing the influence of reputation on the comparison.

Quality has a context.

Sentence patterns and estimated costs add useful detail. They support your decision; no single number can choose your voice.
