Vellum
Build AI agents using plain English to do your boring tasks
Visit website →About
Vellum lets a user build AI agents by describing a task in plain English. Vellum turns the description into a working agent that can be run on a schedule, triggered via an API, or used through a simple UI.
There is no code to write and no setup: the result is an automation the user can understand and adjust by editing the description.
It is aimed at operators and business users who want to automate repetitive or well-defined tasks, data pulls, notifications, routine processing, without learning an automation platform or writing scripts, and want to keep control over what the agent does.

Why we picked it
Vellum made the cut for staying legible — because the agent is generated from a plain-English description, you can actually read and adjust what it does later, which most "no-code agent builder" tools don't make easy once something breaks.
