Serif drafts in your voice. Tacitry drafts in your voice AND earns the right to send for you.
Tacitry and Serif both pre-draft AI replies in your voice; the difference is what happens AFTER the draft. Tacitry graduates trusted recipients off your review queue via per-recipient earned autonomy — Serif keeps every draft in the review loop forever.

Frequently asked
- Serif and Tacitry sound similar. What is the real difference?
- Voice-matching is table stakes for both. The difference is what comes after: Tacitry graduates trusted recipients off your decision queue once drafts to them stop needing corrections. Serif keeps you reviewing every draft forever. Same bet on voice; different bet on what to do with it.
- Could I use both?
- Not really — they would both try to draft replies in the same inbox and overwrite each other. Pick one.
- What about Serif's follow-up tracking?
- Tacitry surfaces threads marked for follow-up but does not automatically nag. We took the deliberate stance that auto-follow-up corrodes relationships; users can disagree and we can revisit.
- Is Tacitry as polished?
- Honest answer: Serif has a longer head start on UI polish. Tacitry's bet is that the loop (voice + autonomy + CRM context) matters more than the chrome, and the chrome catches up over time.
