How to Train Your Own AI, And Make It Sound Like You
by Emily Nichols | 10th Dec 2025 | Hethel Innovation
Let’s be honest: a generic robot voice just won’t cut it for frame-breaking innovators or wordsmiths with a cause. Thankfully, you can teach your AI to write more like you, and it’s far easier than you would think.
Why Bother?
If you want your brand to sound “serious, friendly, and innovative”, or like Bluey met a business accelerator, you need more than spellcheck; you need your style in every sentence.
When your AI assistant writes like you, content gets easier, faster, and a lot more fun. Think: less editing, more productivity.
Step 1: Curate Your Greatest Hits
Dig out your boldest blogs, wittiest emails, can’t-miss LinkedIn posts, and transcriptions of you talking. Five to ten samples will suffice, but prioritise quality over quantity.
Make sure these pieces reflect all your good traits: clear, motivational, practical, and maybe even a cheeky reference, to keep your audience engaged.
Step 2: Spell Out Your Brand Personality
Write down what people should feel when they read your words. Maybe it’s “problem-solving and uplifting with an innovative-friendly wink.”
Get specific: do you like short, punchy sentences or storytelling with data? Formal or casual? Curious or straight to the point? Add a brief summary like: “My tone is encouraging, no-nonsense, and always has time for a clever metaphor.”
Step 3: Feed Those Samples to Your AI
For prompt-based tools, paste your examples right into the prompt. Don’t forget to add guidance: “Use a friendly, practical tone and avoid sounding like a textbook.”
If you’re going deeper (fine-tuning), export your top texts and upload as your ‘brand flavour pack.’ Follow instructions for your AI platform.
Step 4: Test & Feedback
Run a few drafts. Does the AI sound eerily like your morning pep talks? Or is it channelling a newsreader? Tweak as needed
Feedback is key, let your AI know what works (warm, purposeful, a dash of wit) and what doesn’t (corporate mumbo-jumbo), and keep working with it till you feel like you’re getting close.
Step 5: Edit and take it back
Now that you have your draft, take it back into your own hands and refine it. Use it like your assistant, but remain the editor, heart, and soul behind the piece.
Wrapping Up
Training your own AI to mimic your voice isn’t science fiction; it’s an innovation toolkit for today’s marketing pros, startup founders, and content dreamers. It can mimic your quirks, your best lines, and that spirit and get ready to speed up your workflow. It’s your virtual assistant, trained your way, but not quite you.
