Issary Mail

Issary is a desktop email client for people who get a lot of email. It
reads the long threads, drafts the replies, and keeps every account in one
place — so you spend less time in your inbox.

AI where it actually helps

• Draft, rewrite, and refine replies in seconds — in your tone.
• Turn long conversations into short, actionable summaries.
• Issary learns your inbox as you use it: the more mail it sees, the more accurate search and AI context become.

Email, handled properly

• Unlimited accounts in one clean three-pane interface (any IMAP/SMTP account).
• Built-in calendar with Month, Week, and Agenda views — recurring events included.
• Meeting invites right in your inbox: accept, decline, or reply tentative without leaving the app.
• Local-first: your email is cached on your machine — fast and private by design.

Free to download and use as a full email client, with 10 AI-assisted actions per day included. Paid plans add managed AI access (no API key needed) — or use your own provider key.

Issary is actively developed — new features and improvements ship continuously.
