Casely — QA Test Case Generator

Casely is a Virtual QA Lead. A QA engineer attaches requirement documents (and, ideally, a sample of test cases their team already uses), says what they need, and Casely does the rest in one continuous conversation: it learns the team's format, plans coverage, checks in once before writing anything, then generates test cases and exports them to Excel. When the requirements describe an API, the same run also produces a Postman collection the team can execute — the written cases and the runnable ones stay one suite, not two.

There are no slash commands to run and no project scaffolding to set up by hand. Casely reads attachments the way Claude reads any document — natively. This works the same way in Claude Code, claude.ai (web), and the Claude desktop app.
