How to build a voice profile that actually sounds like you
Do not feed the model a random pile of old content. Give it the writing that reflects how you sound now.
Better voice matching starts with better examples. Train Letterflow on recent writing you still stand behind.
Use examples you would still publish today
Your voice profile should represent the version of your writing you want more of. If your sample set includes old, flat, or off-brand work, the outputs will drift in the same direction.
- Choose published posts over rough drafts.
- Favor recent examples if your tone has shifted.
- Include the platforms where voice match matters most.
Show the patterns behind your writing
Letterflow is not only learning words. It is learning rhythm, sentence shape, level of detail, and how you usually open and close an idea. Good samples make those patterns easy to see.
- Include examples with your normal pacing and paragraph shape.
- Keep the transitions and framing moves you use often.
- Avoid one-off lines you would never write again.
Stop writing social posts from scratch
Letterflow turns one newsletter into a week of platform-ready content so your promotion starts with the writing you already trust.
Retrain when your writing actually changes
You do not need to retrain every week. Update the voice profile when your public writing has genuinely shifted, like a new format, audience, or point of view.
- Retrain after a positioning change or new content format.
- Replace samples that feel outdated or too careful.
- Judge the output against your latest published work.
