Personal AI assistant that runs your tasks in a hosted environment. Plans priced by 'computer size' (small/medium/large) and included storage (10/30/60 GB), with each tier bundling usage.

What each is best for
Postman is worth it if… engineering teams (3-500 developers) that build, test, and consume APIs — particularly if you have more than 5 developers hitting the same API surface. Free covers solo learning + hobby projects (3 collaborators); Basic adds unlimited history and version control; Professional adds unlimited collaborators, SSO add-on, and 100K API calls; Enterprise adds SCIM, audit logs, and unlimited scale.
Vellum is worth it if… individuals who want a persistent AI assistant that can execute multi-step tasks, keep files in a hosted workspace, and be reached via a custom email or subdomain. Mighty $30 suits casual daily use; Super $100 adds email/subdomain features for prosumers; Ultra $200 targets power users who lean on the assistant heavily.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
