Tacitry drafts and sends replies in your voice once you've trained it; Shortwave reorganizes your inbox with AI bundles and summaries. Different jobs at different layers of the stack — Tacitry is reply-side, Shortwave is read-side. Bundles, summaries, semantic search are Shortwave's bet that AI should help you read and triage email. Tacitry's bet is that the next step is having something reply for you.
Why do people use Shortwave?
- Thread summarization saves real time on long internal chains.
- Bundles surface what matters without forcing zero-inbox discipline.
- Strong AI assistant for asking questions across your mail history.
How is Tacitry different from Shortwave?
- Reply-side, not read-side. Reading is a smaller fraction of email pain than writing.
- Persistent voice and rules. Shortwave's assistant starts fresh every conversation; Tacitry remembers what you corrected last week.
- Earns autonomy per recipient. Shortwave does not send for you; Tacitry sends when judgment converges.
- Calendar handling — Tacitry RSVPs to invites with availability checks. Shortwave does not.
Switching from Shortwave takes about a day. We do the setup; you keep your inbox.

Frequently asked
- Could I use both?
- You could, but they overlap less than you might think. Shortwave changes how you read; Tacitry changes how much you have to read.
- Does Tacitry summarize threads?
- It uses thread context internally when drafting, but does not show you summaries — the goal is for you to not have to open most threads at all.
- What about the inbox UI?
- Tacitry does not replace your inbox. You stay in Gmail; Tacitry handles drafting and sending. The decision surface is a separate review queue.
- Does it work for non-business email?
- It works for any email — but the autonomy curve only matters where you have repeat-recipient patterns. Personal email rarely has those.
