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.
