The Copy Studio

Read the copy you have. Write the copy you need. Marketing · Social · Article · Bio.

A genre-specific lens on what your writing is doing — and quietly hiding. Reader analyzes a piece you've already written. Writer drafts a new one from a short brief. Either way, you see who you're reaching, who you're missing, and the voice you're using vs. the voice you might be aiming for. Built to give you what a generic LLM won't: specificity, by genre.

Setup · two quick questions

Let's tune the lens.

Every genre rewards different moves. Pick yours, then tell us whether you want feedback on writing you've already done, or help drafting something new.

1. What kind of writing?

2. Read what you have, or write something new?

Step 1 of 3

Paste your copy

A landing page, product page, about page, email, or campaign. Anywhere from a paragraph to ~5,000 words works well. Strip navigation and footer noise — the cleaner the copy, the sharper the analysis.

Copy and paste it into Claude, ChatGPT, or any model. The format strings (`> "passage"`) are required — the renderer parses them.

Step 5 — Compose

Run · Step 2 of 3

Run this prompt in your chat

Copy and paste it into Claude, ChatGPT, or any model. The prompt asks for three contrasting variants — different recipes of rhetoric and audience targeting — so you can compare angles rather than commit to one.

Build from here · conversation kickstarter

Take this prompt to your chat

Copy this and paste it into Claude or ChatGPT. The prompt tells the LLM about your chosen variant and the recipe behind it, then asks the model to ask you a few questions before drafting — so you develop the piece through conversation rather than getting a one-shot expansion.
