Jace AI

Jace AI works by securely connecting to your email inbox and learning your communication patterns, tone, and company context from the start — no manual training needed. When a new email arrives, the platform analyzes the message alongside relevant attachments, checks your calendar, and reviews related Slack conversations to produce a draft reply with full context already built in. Beyond drafting, Jace applies AI-generated labels to incoming mail based on priority and content type, so you can immediately identify urgent messages without reading every subject line. Smart Rules let you define automated actions — like always CCing a specific team member on contract threads — and business integrations allow incoming emails to trigger Slack notifications, create support tickets, or save documents without any manual handoff between tools. Jace is used across a range of professional roles where email volume is a genuine productivity drain. Read our guide. A startup COO might use Smart Rules to route legal-sensitive threads automatically while relying on AI drafts to answer vendor queries in seconds. A sales manager can use AI labels to surface hot leads from a crowded inbox each morning. Consultants managing multiple client accounts can connect up to 8 inboxes under one Pro account and query years of email history using the AI Chief of Staff feature — asking natural language questions like 'What did the client say about the Q2 deliverable?' and getting a direct answer pulled from historical threads. The platform also supports MCP integrations and custom workflow setups on the Pro tier Browse tools.
