Teaching Claude your writing style

What it is good at

• Very responsive to being shown a real example rather than being told an abstract description of tone.
• Can articulate a style precisely enough to turn into a reusable instruction for future sessions.
• Holds a style consistently across a long piece once it's locked in, rather than drifting after a few paragraphs.
• Good at explaining why a piece of writing doesn't match a target style, which speeds up correction.

Where it falls short

• A single short sample isn't always enough, two or three pieces across slightly different contexts work better.
• It will follow a style description confidently even if your own correction of it was slightly wrong, so check the description carefully.
• Style consistency resets between separate chats unless saved into a project's instructions.

How to use it for creative work

1. 01

   Gather two or three genuine writing samples

   Pick pieces that represent your actual voice in different contexts, a product description and a longer article, for instance, rather than one single example.

2. 02

   Ask Claude to describe the voice before writing

   Have it break the style into concrete terms: sentence length, vocabulary level, what it never does, emotional register. This forces precision instead of vague impressions.

3. 03

   Correct the description, not the output

   If the description misses something, correct that description directly rather than jumping straight to editing a bad first draft, it saves several rounds of drift.

4. 04

   Turn the finalised description into a saved instruction

   Once accurate, save it as project instructions or a reusable prompt opener so every future piece starts from the same grounded description.

5. 05

   Spot-check against the samples periodically

   On longer projects, occasionally re-paste an original sample next to new output and ask Claude to flag any drift from the original voice.

Ready-to-use prompts

Here are three pieces of my own writing: [paste]. Describe my voice precisely, sentence length, vocabulary, structure habits, what it avoids, and emotional register, as a reusable instruction under 120 words. Wait for my corrections before writing anything new.

Using the voice description we finalised, write a [document type] about [topic] at roughly [length]. Match the voice exactly, not a generic professional version of it.

Compare this new draft against my original sample: [paste both]. Point out any place where the new draft sounds more generic or less like the original voice.

Take this piece written in [source style] and rewrite it fully in my established voice, keeping every fact and claim exactly the same.

Turn our finalised voice description into a short instruction I can paste at the start of any future chat to get this same style immediately.

Questions people ask

How do I make Claude sound less like an AI?

Show it real samples of writing you like, your own or a reference, and ask it to describe the voice precisely before writing, rather than telling it to 'sound human', which is too vague to act on.

Does Claude remember my writing style between chats?

Not automatically outside a project; save the finalised style description as project instructions or a reusable prompt to carry it into every new chat.

How many writing samples does Claude need to match my style?

Two or three samples across slightly different contexts generally work better than one, since a single sample can lead it to over-fit to that specific piece rather than your general voice.
