Open Envelope

An AI agent designer and generator that converts plain-language workflow descriptions into structured AI agent designs, including roles, skills, models, tools, and handoffs. It solves the problem of designing multi-agent systems from scratch by providing an opinionated framework. The product targets developers, IT teams, and engineering teams in companies of all sizes, especially those using tools like Slack, HubSpot, Notion, Stripe, and Jira. It differentiates itself from general chat tools by outputting a structured JSON spec that can be stored in Git and implemented directly, with an open schema (Apache 2.0) to avoid lock-in.
