Promise remembers what matters, not just how fast you move through email.

Superhuman helps you move through email faster

Superhuman is known for a fast, keyboard-driven inbox experience. Promise has a different job: remembering commitments, follow-ups, dates, and important details after conversations have moved on.

How Promise is different

• Promise remembers follow-through from Gmail and Outlook.
• Promise can also capture short voice notes when the commitment starts outside email.
• Promise keeps source evidence near extracted actions where possible.
• Promise does not require moving your team into a new inbox interface.

When Promise is the better fit

Use Promise when the risk is not inbox speed but lost accountability: a customer follow-up mentioned in a thread, a reminder you spoke while walking between meetings, or a person-specific detail you need at the right time.

Use both if email speed matters

Promise does not replace an email client. If your team already uses a fast inbox workflow, Promise can sit beside it and focus on the follow-through that should resurface later.

Boundaries

Promise is not affiliated with Superhuman, does not claim to replace Superhuman, and does not send messages without explicit user review and confirmation. It helps users inspect possible follow-through before acting.
