A summary that shows its sources

Ask for a summary only when you want one. It reads the top results, never your whole mailbox, and stays underneath the messages it came from.

  • CitedEach sentence names the numbered message it came from. Sentences without a source are marked as unsupported.
  • CheckedInvoice numbers, dates and amounts in a summary must appear in the cited message, or the sentence is flagged.
  • LocalAn optional 2.7 GB model runs on your processor. Mailglade checks memory, cores and disk space first and tells you if this computer will be slow.
  • OptionalNothing is summarized automatically. Free includes three summaries a day.

What stays on your computer, and what does not
