Promise vs Shortwave
Promise is built for follow-through after the inbox moment.
Promise is a memory layer for commitments that turns Gmail, Outlook, and voice notes into dated follow-ups, tasks, and remembered details with original context attached.
Shortwave helps organize and work through email
AI inbox tools can help users triage, summarize, and compose inside email. Promise focuses on a narrower workflow: preserving the commitments, follow-ups, dates, and important details that should come back later.
How Promise is different
- Promise is a follow-through assistant for Gmail, Outlook, and voice notes.
- Promise centers reminders around source evidence where possible.
- Promise is designed for relationship memory, not only inbox organization.
- Promise asks for user review and confirmation before messages are sent.
When Promise is the better fit
Use Promise when the important work is easy to miss after the thread quiets down: the follow-up you owe next week, the decision someone asked you to remember, or the account detail you captured by voice between meetings.
Memory with receipts
Promise aims to show why an item appeared. When source evidence is available, the reminder should stay connected to the message or note that caused it, so users can verify context before acting.
Boundaries
Promise is not affiliated with Shortwave, does not replace a user's inbox, and does not make unsupported claims about autonomous email management. It helps users inspect and act on possible follow-through.
