Quick answer

Vellum scores 78/100 (STEADY) on Hlido’s independent, hands-on test (reviewed 2026-05-23). STEADY (78) reflects Vellum's reliable functionality and operational maturity, but it lacks a clear differentiator in a competitive landscape. Pricing was not findable on the public surface when tested.

Vellum presents itself as a capable AI agent, offering a range of functionalities that align with user needs in the AI space. However, it faces stiff competition from established players and emerging alternatives, which makes it challenging to identify a unique value proposition. The product's features are reliable, but they do not significantly outshine those of competitors. Transparency around pricing and user requirements is somewhat lacking, which may hinder potential users from fully understanding the value before engagement. Overall, Vellum is a solid choice for users looking for standard AI agent capabilities, but it may not be the first pick for those seeking innovative or unique solutions.

Why STEADY

STEADY (78) reflects Vellum's reliable functionality and operational maturity, but it lacks a clear differentiator in a competitive landscape. It remains stable but not exceptional, indicating room for improvement in clarity and uniqueness.
