Jace is an AI email agent from Zeta AI, Inc. that sits on top of a user's inbox to draft replies, organize messages, and act on incoming mail. The company describes it as an AI executive assistant, and its site claims users can reclaim 90% of their email time. Its stated mission is to end inbox overwhelm with an agent that finds context and drafts in the user's voice.
The product is aimed at professionals and business leaders who handle high email volume. Beyond drafting, Jace offers rules, labels, business integrations, and a chat assistant called AI Chief of Staff. The company also promotes a separate AI employee offering for teams that need more hands, though the sources give no detail on how it works or what it costs.
Setup has three steps according to the site. First, the user connects an email inbox, which the company says takes about one minute. Next, Jace onboards itself in roughly five minutes, learning the user's writing style and company context without manual training. Finally, the user reviews the organized inbox and approves drafts, which the site frames as saving about two hours a day.
When drafting, Jace pulls in context automatically. The homepage says attachments are analyzed, the calendar is checked, and Slack discussions are reviewed, so the user spends about five seconds reviewing a draft instead of ten minutes researching. The FAQ includes a question on whether Jace sends emails automatically, but the answer text is not included in the available pages.
Jace's drafting feature produces replies in the user's tone, and a custom instructions feature lets users fine-tune how it responds, according to a customer testimonial. Smart Rules handle repeated tasks such as adding CCs, applying templates, and triggering actions based on who the user is emailing. AI Labels sort mail by type and priority, with examples like urgent client, partnership, and internal updates.
Business integrations trigger actions when emails arrive, including creating tickets, sending Slack notifications, and saving documents. AI Chief of Staff lets users chat with Jace to fetch data, create documents, and automate tasks. Higher plans add longer email search history, more connected inboxes, and custom integrations and MCPs. Security claims include SOC 2 Type 1, encryption in transit and at rest, and no training on user data.
