Jace is an AI email assistant built by Zeta Labs, a London startup founded in 2023 by former Meta engineers Fryderyk Wiatrowski and Peter Albert. The company launched its first product in mid-2024 as a general browser-operating AI agent, backed by a $2.9 million pre-seed round led by former GitHub CEO Nat Friedman and former YC head of AI Daniel Gross, before narrowing its focus specifically to email productivity.
Jace connects to Gmail and drafts context-aware replies by referencing prior email threads, so a user reviews and sends rather than writing from scratch. The product also organizes an inbox automatically, surfacing what needs a response and drafting a set number of pre-written replies each day depending on plan. Zeta Labs originally built Jace around a proprietary web-interaction model called AWA-1 for general browser automation before repositioning the product around this narrower, higher-retention email use case.
Jace suits professionals with high email volume, such as founders, salespeople, and recruiters, who want drafts ready before they open their inbox rather than a general-purpose browser agent. The Plus plan starts at $20 a month billed annually (or $25 month to month) for up to two inboxes and 10 daily drafts; a Pro plan at $40 a month annually adds more inboxes and integrations. A 7-day free trial requires payment details upfront.
