How it works
Sent-mail fingerprint
Pranan analyzes hundreds of your sent emails to learn how you actually write.
Per-recipient adaptation
How you write to your co-founder is different from how you write to your investor. Pranan respects that.
Sharper over time
Every send teaches the model. By month two, drafts feel like muscle memory.
Common questions about voice matching
How long until drafts feel native? Most users see usable drafts within 24 hours of connecting Gmail. The fingerprint sharpens over the first two weeks as the model sees more of your sent mail. By month two, drafts feel like muscle memory.
Does voice matching work for cold emails? Yes, but with caveats. Cold emails have less thread context to anchor voice, so the AI relies more heavily on your fingerprint. Cold emails generated this way still outperform generic-templated outbound by a wide margin.
Can you turn it off for specific recipients? Yes. Per-contact opt-out is a one-click setting. Useful for legal counsel, board members, or anyone you'd rather draft to manually.
