Anyone else using EchoWriting to make AI actually sound like you? Here's what's been working for me

I've been deep into prompting for a while now, mostly with Claude and ChatGPT for work emails, blog drafts, and even some creative stuff. But everything always came out feeling a bit... polished and generic, you know? Like it had that unmistakable AI sheen. Then I stumbled on EchoWriting and it's honestly been a game changer for getting the output to feel like it came from my brain instead of a model.

For those who might be new to it, it's basically feeding the AI samples of your own writing (or describing your quirks really specifically) so it echoes your voice back. Not just "write casually" - but stuff like "I tend to use short sentences when I'm making a point, throw in occasional sarcasm, and I love parentheses for side thoughts (like this)."

My current workflow that's been solid:

• I keep a Google Doc with 4-5 paragraphs of my own writing from different contexts (emails, Reddit comments, personal notes).
• Start a new chat and paste a couple examples + a detailed style description.
• Then give the actual task: “Rewrite this draft in my style: [paste draft]”
• After the first version, I usually do one round of “tweak this to sound even more like me — add more contractions and make the transitions less smooth.”

It's not perfect every time, but after a few iterations it gets scary good. I've used it for client proposals where the feedback went from "this reads well" to "this feels exactly like how you talk in meetings." Saves me so much time rewriting AI slop.

One tip that made a big difference: Include things you don't do. Like "Avoid starting sentences with 'In conclusion' or 'Delve into' - I hate that corporate fluff". Or "I ramble a bit when excited about an idea."

Has anyone found good ways to make it work across Claude vs ChatGPT? Or do you have favourite prompts for capturing tone/quirks? Also curious if people are using it for longer form stuff like articles or if it shines more on shorter pieces.

Would love to hear what's working (or not) for you all.

Cheers!
