Postman is the most widely used API development platform — providing tools for API design, documentation, automated testing, mocking, and team collaboration for developers building and integrating APIs. Postman AI introduces Postbot — an AI assistant embedded throughout Postman that generates test assertions, writes test scripts from natural language descriptions, suggests API documentation, and explains API responses. Test Generation from AI creates comprehensive test suites — Postbot analysing API requests and generating test assertions for expected response codes, response body fields, and schema validation without manual test writing. API Design support includes OpenAPI schema editing with AI suggestions — generating API endpoints from natural language descriptions of the intended API behaviour. Collections organise API requests into shareable groups — enabling teams to share and collaborate on API test suites, documentation, and workflows. Mock Servers simulate API responses — enabling frontend developers to build against APIs that don't exist yet and testers to test without live backend dependencies. API Network provides a public API discovery platform — finding and forking public APIs from thousands of companies for integration. Monitors run automated API health checks on schedules — testing production APIs continuously and alerting when endpoints fail or respond slowly. With 35M+ developers using Postman, it validates as essential API development infrastructure across every engineering team building APIs.
Postman AI runs as llm assistant software built around code and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, desktop, and cli, with API access for teams that want to embed it into their own products.
The capabilities that matter most for teams evaluating Postman AI.
AI test generation, documentation suggestions, and response explanation — reducing manual test writing and documentation effort for API development.
Organised shareable API request groups with tests and documentation — team collaboration on API development workflows.
Simulated API responses enabling frontend and QA teams to work without live backends — parallel development without backend-frontend coupling.
