Jace

Jace is an AI email assistant that drafts replies, organizes the inbox and carries out email-driven tasks for busy professionals. It connects to your existing accounts rather than replacing your email client, and it acts on what arrives: a draft is waiting when you open a thread, labels show what matters, and rules or integrations take care of the follow-up work. Its chief-of-staff chat is the agent part, letting you ask Jace to find information or complete tasks across your mail.

What is Jace used for?

Jace is used to cut the time spent reading, sorting and answering email, and to move information out of the inbox into the systems where work happens.

• Drafting replies that draw on attachments, calendar availability and Slack messages
• Labeling incoming mail by type and priority so important threads surface first
• Applying smart rules for automatic CCs, templates and repeat actions
• Creating tickets, posting Slack notifications or saving documents when certain emails arrive
• Asking the AI chief of staff to find facts in past mail or carry out a task
• Managing several inboxes and calendars from one assistant

Who Jace is best for

Jace suits founders, executives, sales leaders and operators who receive a heavy volume of email across more than one account and want drafts ready rather than rules to maintain. People who are happy with their current email client and want an assistant layered on top will like the approach. Light email users, or anyone who wants a full new email app with its own interface, may prefer a different product.

Jace pricing

As of October 2026, Jace offers two self-serve plans billed yearly. Plus costs $20 per month with 10,000 credits a month, two connected inboxes and one year of email history. Pro costs $40 per month with 20,000 credits, up to eight inboxes and three years of history, and the page also shows a $50 figure for Pro, likely the monthly billing rate. Both include unlimited calendars and a 7-day free trial, and Jace mentions a 30-day money-back guarantee. Enterprise pricing is available from sales.

Limitations to keep in mind

• There is no ongoing free plan, only a trial
• Credit allowances cap how much AI work each plan covers
• Giving an assistant full mailbox access needs a review of its security posture
• Drafts still need a quick read before sending, especially to customers

Jace vs alternatives

Fyxer AI is a close alternative focused on inbox sorting and drafts in your own voice, with a strong following among small business owners. Superhuman is the better choice if you want a fast new email client with AI features built in. Shortwave suits Gmail users who want an AI-first email app with search and summaries. Lindy fits people who want email to be one part of broader custom agent workflows. Jace wins when you want drafts, rules and email-triggered actions without switching email clients.

Tips for getting started with Jace

Connect your busiest inbox first and let Jace draft for a few days before setting up rules, so you can see what it gets right. Add your calendar and Slack early, since that context improves drafts. Set up one integration, such as creating a ticket from support emails, to test the workflow features on a real process.
