How to find your real writing voice, with the exact prompt
Build your own AI assistant

Find your voice in your own inbox.

Your AI drafts sound generic for one simple reason. You never showed it how you actually write.

Here's the fix. It takes about 15 minutes, and you can copy the prompt below exactly as written.

If you connected your email in the last guide, use this

Open your project and paste this in:

COPY THIS
Look through my sent emails from the last few months and study how I write. Then give me a short style guide covering: my typical sentence length, how I greet people and sign off, how formal or casual I am, phrases I repeat often, and how I say no or follow up on something. Back up each point with a short real example from my emails. Don't summarize what the emails are about. Only describe how I write them.

If you haven't connected your email, use this instead

Find 8 to 10 emails you've actually sent (real ones, not your best work) and paste them into the chat right after this prompt.

COPY THIS
Here are several emails I've actually sent. Read them and write me a short style guide describing how I write: typical sentence length, my usual greeting and sign-off, how formal or casual I am, phrases I repeat, and how I say no or follow up. Use real lines from these emails as examples. Don't summarize the content. Only describe my writing style.

Read it, then correct it

The first version will be close, not perfect. Maybe it says you're more formal than you are. Tell it what's wrong, in plain language, like "I'm actually more casual than that" or "I never use exclamation marks." That correction matters more than the first draft did.

You now have a style guide. Save the final version. You'll paste it into your assistant in the next step.

What's next

Build your assistant, using the connection from step one and the voice guide you just wrote.
