A privacy-first email client with built-in AI writing help
Pull Gmail, Outlook, Exchange, IMAP and POP accounts into one organized view so every message is in a single place.
Summarize long threads, draft replies in your voice, rewrite for tone or length and translate messages without leaving the inbox.
PGP and S/MIME support with keys you generate or bring yourself, plus tracker blocking and a zero-knowledge privacy stance.
Automatic grouping keeps noise down, while the Later board lets you park messages and pick them up when they are relevant.
An AI email assistant that drafts, summarizes, and perfects your messages in place
Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
