Complex contracts.Clear design.
Vellint helps engineering teams turn complex source documents into structured, reviewable design narratives—with requirements, engineering input and decisions connected from source to saved revision.

Follow complex project information from source documents through engineering reasoning to a reviewable design narrative.
Read the film transcript
The film uses music only; there is no spoken narration.
A tender arrives with requirements across PDFs and a design narrative to deliver. The team starts with a controlled source set, chooses a deliverable and prepares its evidence. Requirements provide the evidence; engineers provide the decisions. Vellint brings both into a reviewable design narrative in the company template, with the reasoning and source trace visible. When a requirement changes, the team sees what needs review while the earlier revision is retained. Less searching, clearer reviews. Complex contracts. Clear design.
A practical use case for engineering AI.
Give engineering teams a controlled way to understand requirements, resolve inputs and produce reviewable design narratives.
