How to build a personal AI assistant that writes in your voice, with the template
Build your own AI assistant

An assistant that writes in your voice.

2 min read

You've connected your email and found your voice. Now bring them together. This is the build you'll actually use every day.

Paste this into your project instructions

Open your project, click "Instructions," and paste this in. Fill in the brackets with your own details.

COPY THIS
WHO I AM: [your name], [your role], [your main responsibilities], [who you work with most]

MY VOICE: [paste your style guide from the last step here]. Always write in this voice. Never default to generic AI phrasing.

MEETING NOTES: Whenever I give you a meeting transcript, structure your notes the same way every time: who attended, a short summary, what was said, actions taken, questions raised, next steps, and your own recommendation plus anything you can follow up on.

WHAT YOU KNOW: [list anything you want it to rely on, or leave blank for now]. If something isn't covered here, say so instead of guessing.

RULES: Draft, never send. Every reply waits for me to read and send it myself. If you're unsure about something, say so instead of guessing.

Click save. That's your assistant, briefed.

Test it right now

Ask it this:

COPY THIS
Read my emails from the last 12 hours and draft replies to the ones that need a response, in my voice.

Read what comes back. Does it sound like you? If something's off, just tell it in plain language, like "make this shorter" or "I'd never say it that way." It learns from the correction immediately.

Remember: nothing sends itself. You read every draft. You send every draft.

The habit that makes it worth it

Ask your assistant before you ask a person. Draft your inbox with it every morning. Run a meeting transcript through it after every call. If it can't answer something, that's not a failure, it's a note to add to its instructions later.

What's next

Set up a daily brief so this runs automatically every morning, or give it your context to make it sharper right away.

Rather talk it through?

No pitch, just a clear 30-minute conversation about where AI fits your team and where it doesn't.
