Add and validate AI-predicted annotations inside Lexis360 and Sesame documents
Add your own annotations to the document currently open in the browser, without leaving the host application.
Contacts internal SIE web services to fetch annotations produced by a prediction AI component for the document you are viewing.
Review and validate returned annotations so that human judgement is applied before labels are accepted.
Designed specifically to help classify and categorise documents in editorial and legal content workflows.

Design, test, and govern APIs — now with AI agents in the loop
A multi-protocol client with collections, environments, variables, and reusable requests that works for local debugging and for driving automated test suites.
Generates assertions automatically, supports data-driven runs with exported datasets, and executes tests locally, in the cloud, or from CI pipelines via the Postman CLI.
Agent Mode, the Postman CLI agent skills, and a Model Context Protocol server let coding assistants build collections, write tests, and trigger API workflows from inside the editor.
A structured, queryable map of an organization's APIs, collections, and dependencies that lets agents find the right service and understand what a schema change would break.
