What changes when AI handles triage.
Firms spend hours every week reading through email just to decide what needs action. Legasus Mail AI changes that.
- Unread threads pile up
- Staff rereads long conversations
- Important context stays buried
- Attachments get missed
- Leads wait too long for a response
- Threads summarized instantly
- Urgency is easier to spot
- Next steps are suggested
- Matter matches are recommended
- Drafts are ready for review
One AI. Four capabilities.
Mail AI runs four passes on every incoming thread: thread summaries, urgency scoring, sender classification, and matter matching. Your team focuses on acting, not reading.
Thread summaries
Turn long conversations into clean, scannable summaries so attorneys and staff can understand the context faster.
Suggested next steps
See ranked actions based on the thread, sender, matter context, and firm workflow.
Matter matching
Get suggested matters with confidence scoring and one-click confirmation.
Draft assistance
Generate replies that match the user's writing style, ready for review, editing, and approval.
Turn an inbox into a prioritized action list.
Mail AI processes incoming threads, flags urgency, classifies the sender, and surfaces suggested actions so your team can work through email in order of importance.
- 1
Email arrives in Legasus Mail
Incoming messages sync from Gmail, Outlook, or Microsoft 365 into the Legasus Mail inbox.
- 2
AI generates a thread summary
Key facts, people, dates, and open questions are extracted and displayed inline.

Sender is classified automatically
The sender is labeled as client, lead, court, opposing counsel, vendor, or internal team member.
- 4
Urgency and next steps are identified
Mail AI flags urgency and surfaces ranked suggested actions based on the thread and matter context.
- 5
Draft queued for approval if needed
If a reply is needed, Mail AI can prepare a draft that waits for user review before sending.
Identify new leads before they fall through the cracks.
When a potential client emails your firm, Mail AI recognizes the inquiry, extracts the key facts, flags urgency, and prepares a suggested intake action for your team to review.
- 1
Email arrives in intake inbox
Shared inboxes like intake@ or contact@ are connected and monitored in Legasus Mail.
- 2

Key facts extracted automatically
Incident type, urgency signals, contact details, and timeline are surfaced from the message.

Suggested intake action prepared
Mail AI suggests creating an intake record or linking the thread to an existing one.

You decide what AI can and can't do.
Every Mail AI capability can be enabled, restricted to specific roles, or turned off entirely. Admins configure AI behavior per mailbox, per user, and per firm.
Built for law firms that take confidentiality seriously.
Mail AI is designed to help firms move faster without compromising client confidentiality, ethical obligations, or data security.
Approval-first AI
AI can prepare summaries, recommendations, and drafts, but emails require user approval before sending.
Mailbox-level controls
Admins can decide which mailboxes can use AI summaries, classification, drafting, and automation.
Matter-aware permissions
Access to mail linked to a matter respects matter permissions, ethical walls, and firm-level access rules.
No model training on customer data
Customer email content is not used to train public models. Legasus is built privacy-first.
