A brand voice generator that learns from what you've already written

How it works

1. 01

   Paste your website or writing samples

   PostKeel reads what you've already published and suggests a starting voice archetype — direct operator, warm practitioner, quiet authority, and others — based on how you actually write.

2. 02

   Calibrate with two quick ratings

   Rate whether a sample draft sounds like you. Two rounds is usually enough to lock it in — no lengthy style guide to fill out.

3. 03

   Every draft follows it after that

   Register, word choices, and banned phrases stay consistent across LinkedIn, Instagram, X, and blog posts — not a different voice per channel.

4. 04

   It keeps sharpening

   Every edit you make teaches PostKeel a little more about your actual voice, not just the archetype's default.

Why this works better than a tone-of-voice doc

• Starts from what you've actually written, not a description you have to write yourself
• Six real starting archetypes, each with a concrete example — not vague adjectives like "friendly but professional"
• Calibration takes two ratings, not a workshop
• Consistent across every channel, automatically — no separate style guide to maintain
