Stamp is an AI secretary for email and calendar. The company describes it as an assistant that learns a user's preferences so it can draft, prioritize, summarize, and schedule in that person's voice, using their own context. Its tagline is Email, handled.
The idea is that routine inbox work can be prepared by software and approved by the user. The site lists Features, Pricing, Downloads, and a blog, and it promotes a Stamp Mobile app for working away from a computer.
Stamp learns through three features. Memories are created automatically about the user and their contacts after each interaction, and they can be edited by hand. AI Labels are written in plain English, with actions attached to each label. Context Search looks through the inbox and calendar to understand writing style and availability.
With that context, Stamp drafts replies when emails arrive and categorizes and prioritizes the inbox. In Stamp Mode, the user moves through the inbox by approving those changes, and the Agent handles delegated tasks by chat.
On the inbox side, Stamp offers automatic replies, automatic labels, a priority inbox that keeps important emails at the top, and summaries with extracted todos. Label actions let users specify what Stamp should do with every email in a given label.
The Agent and Composer cover delegated work. They can bulk draft replies from a single prompt, search the web, populate recipients from contacts and past emails, create or modify calendar events, and archive, trash, or categorize emails. Answers drawn from email include citations.
