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.

Payments infrastructure that lets AI agents buy services autonomously within limits you set
Set an amount, a purchase count and an expiry before an agent can pay. Every transaction is checked against the mandate, and only you can raise the limit.
A vetted catalog of paid AI services agents can buy per call, reachable through one integration rather than many separate vendor accounts.
Settles merchants over card, Visa agentic tokens or crypto rails, so agents pay inline without a checkout flow.
Stop an agent's ability to spend with one dashboard click or API call, with no grace period and no residual purchasing power.
