Creator Studio, running on your own model key

Write it once. Every draft points back to what you wrote.

Paste one piece you wrote. Your own model drafts the week’s posts, newsletter and page section. The studio checks each sentence against your paragraphs and marks what it cannot trace. Nothing is published from here, and only the drafts you approve go into the export.

Your source

One piece you wrote: an essay, a talk transcript, a newsletter issue. The sample is a fictional field note; replace it with yours.

When you run the studio, your source and your instructions go from this tab to Anthropic on your key. GenCreator never receives the key or the source. You pay Anthropic for what you run, and switching provider clears the key. Get a key

What a checked draft looks like. This one was written by hand for the sample to show the marks: two sentences are wrong on purpose.

LinkedIn post

Example, written by hand for the sample

For 11 years I sent every client a 12-page report every Friday. Then a finance director told me she had not opened one since January.

We cut it to one page with three questions: what changed, what we decided, and what we need from you. Choosing what to leave out is the work.

By June her team had replied to 8 of the 12 one-page notes. Response times dropped by 40%. (This number is not in your source: 40%) It also doubled the size of every account we kept. (Too few of these words appear in your source)

Most reporting records activity instead of decisions. A short note that asks for one decision gets read.

What the checks can tell you, and what they cannot.

  1. Check 1 of 3

    Every sentence points to a paragraph

    The studio matches each sentence to the paragraph it shares the most words with. A sentence that is mostly your own words in your order is highlighted. A reworded one carries the paragraph number; tap it to read that paragraph.

  2. Check 2 of 3

    What is not in your source is marked

    A wavy underline marks a sentence built from words your source does not use, a number your source never wrote, an added clause, or a “not” your paragraph does not have. It compares wording. Facts still need your review, and some changed meanings will escape the check.

  3. Check 3 of 3

    An approval belongs to one revision

    Approving records a SHA-256 fingerprint of that exact draft. Edit it, or change your source, and it leaves the export until you approve again. Approvals do not survive a reload.
