HERO is a document editor built for structured, interconnected documents such as legal contracts, technical specifications, standard operating procedures and technical manuals. The company describes it as document infrastructure for humans and agents, aimed at legal, operations and engineering teams, and says more than 100 teams use it.
Its main pitch is that documents are built on live data. A team changes a value once and it updates everywhere in the instance. The editor also adds AI assistance, approval workflows and electronic signatures, so drafting, review and execution can happen in one workspace instead of several.
Users write in a structured editor where documents are divided into sections and sub-sections. Dynamic variables and defined terms are embedded as connected nodes, so references between clauses, definitions and values stay linked. Quick preview and definition tooltips let a reader check a referenced item without leaving the page.
Source material can come from connected tools. Gmail and Google Drive can be linked to search a mailbox and read documents straight into a draft. Once a draft is ready, teams can comment, assign tasks, route it for approval, collect signatures and export to docx or PDF.
The structural tools are the center of the product: dynamic variables, smart sections, cross-referencing, quick preview and definition tooltips. Smart autocompletion and keyboard shortcuts are meant to speed up writing, and sections can be collapsed or searched.
On the workflow side, HERO lists comments, task assignment, approval workflows, electronic signatures, version control and real-time sharing. An AI assistant can draft, review, fix or answer questions. For agent use, the company offers an MCP server and an API, and its site links to API documentation and a changelog.
