What Vellum customers say

They present Vellum as both a private model-testing platform and a personal AI that delegates work by voice. Relevant reviews support their low-code workflow speed and assistant quality, while repeatedly exposing evaluation, UI, and onboarding weaknesses. You can attack the gap between their broad delegation promise and the proof, controls, and reliability required for important tasks.

Vellum reviews, read · 18 of 18 read one by one · 2026-08-29T20:01:55.605Z

Among the 17 relevant reviews, they receive strong praise for workflow building, model experimentation, speed, and responsive support. The recurring weaknesses are evaluation depth, advanced-flow complexity, UI roughness, and sign-up reliability. The Vellum book-formatting review is a different product and is excluded from the competitive read.

Feels truly personal

Ava remembers things that I forget, and interacting with her feels more natural than other AI assistants. 11/10

Amazing. Feels like the future.

Vellum is a work in progress, but they’ve managed to create an AI that really gets to know you and can do ANYTHING you ask it to do, so long as there’s an API, MCP, or skill. And if you don’t know what those are, just ask your assistant and they’ll guide you through it all. This seems like the kind of AI we imagined people would have in the future, but it’s here now.

FLOORED!

I have no idea how it’s humanly possible this app could have a 3.9 rating… Absolutely nothing else exists like it at this polished of a level. Not open claw not Hermes agent… NOTHING… this is the future… I just told it to open me an LLC that I needed, it recommended the site with options. I told it yes and it did everything for me! filed an LLC at the website. Made the payment. My jaw was on the floor. You can do anything. You can do similar things yes on other platforms, but you have to use this app to experience the polished execution, the speed , the ease, and accuracy, ALL Without all the setup, you normally need for an open source agent. This team nailed it. good job!
