"After 10 years in B2B, the biggest lesson: users don't want features, they want outcomes."
"Great post, Sarah! This really resonated with me. It's so important to focus on outcomes. Thanks for sharing this valuable perspective! 🙏🚀"
✗ Starts with "Great post" — instant AI tell
✗ Your prospects write the same comment with a different name
✗ No context — same output whatever you actually think

"After 10 years in B2B, the biggest lesson: users don't want features, they want outcomes."
"Ten years in B2B and this pattern keeps repeating. Outcomes beat features every time — the hard part is convincing stakeholders before you have the data."
✓ Saves time, looks credible
✓ Works for most comments, most of the time
✗ Used by thousands of accounts daily — your network has seen it
One more step makes this sound like you actually wrote it.

"Ten years in and this is still the unlock nobody talks about. We reframe every roadmap item as a user before/after state — makes vanity features impossible to greenlight. Learnt this the hard way."
✓ Reflects how you actually write, not how AI writes
✓ Your rhythm, vocabulary, and opinions
✓ Nobody else's output sounds like this

Questions before you install?
Is the AI output actually good?
Yes — but Voice Profile matters more than the model. The banned phrase list, sentence rhythm rules, and your personal style fingerprint constrain the output so it sounds like you, not like generic AI. The model is a commodity; your fingerprint is the differentiator.
How does the free tier work?
You get 5 comments per day, reset at midnight UTC.
Is my data stored anywhere?
No PII is stored. Device ID stays local. Usage counts are anonymous.
Does it read my messages?
Only the draft reply you actively enhance is sent for processing. We don't store your reply text.
What does Pro unlock?
Voice Profile training (every comment sounds like you), unlimited comments, and the same 4 tones and current-tone view. Voice Profile is the main reason to go Pro.
How do I cancel?
Cancel anytime from your subscription management link.
Does it work on mobile?
Desktop Chrome only for now.
Can I use it on Brave or Edge?
Yes, any Chromium browser works.
