Before you start
You need a Microsoft account with an Outlook mailbox. Hebno reads only the mailbox of the account you connect.

Allow sending (optional)
On the Outlook row, select Allow sending and approve
Mail.Send. The same button appears on an email card if you try to send before granting it.What Hebno reads
Hebno returns one result per thread, using the latest message, which quotes earlier ones. Each result shows the subject, sender, date, a link and an excerpt: the first 400 characters plus the most relevant passages. A chat reads up to 5 threads and a research run up to 6. Attaching an email adds it to the message as a Markdown file named after the subject. Attachments on the email are not included.
Hebno never deletes, moves or edits mail. Reads are live, and only the excerpts a reply used are stored with the conversation as its sources.
What Hebno writes
Every email appears first as a card titled Email. You can change any field before you select Send.
An Outlook change pending confirmation. Nothing is written until you confirm.
