Platform · AI Assistant · AI Design Documents
Every reviewer wants the design document and no engineer wants to write it. Write with AI closes that gap: it reads the diagram, describes what it sees, interviews your team a few focused questions at a time, and writes the structured design explanation into the live editor. Ten minutes of talking becomes the document everyone was waiting on.
The definition
A design document explains a system: what it is for, how data moves through it, why the security decisions were made, and what the design assumes. The knowledge exists, in the heads of the people who built the system, but extracting it into a document is slow enough that most design docs are either missing or stale.
Write with AI is an interviewer, not a template. It starts from the architecture diagram (it will decline to explain an empty canvas), describes what it sees so the team can correct it, and then asks two or three focused questions at a time: purpose and boundaries, data flows and sensitivity, the reasoning behind the security decisions, assumptions and dependencies.
The answers become a structured markdown explanation: Overview, Components and data flows, Security controls and design decisions, Assumptions and dependencies, written into the live editor. You click Apply, adjust anything, and save. From there, a single click exports the complete design document as a PDF: project context, people and roles, business impact analysis, every diagram with its explanation, the threat model, and the sign-off matrix.
How it works
The studio builds its context from the shapes and connections on the canvas, the threat model, and the project facts.
A description of the architecture as drawn, so the team corrects misconceptions before a word of the document exists.
Two or three focused questions at a time: purpose, boundaries, data sensitivity, the why behind decisions, assumptions.
A structured explanation lands in the live editor on Apply. You adjust and save; the studio never writes to the database itself.
One click assembles project, people, BIA, diagrams with explanations, threat model, and sign-offs into a reviewable PDF.
The explanation is written against the actual shapes and flows on the canvas, not a remembered version of the system.
The first reply is always questions, not a wall of text, unless you explicitly say 'just write it'.
Overview, components and data flows, security controls and design decisions, assumptions and dependencies: the sections reviewers expect.
The single editor tool never touches the database. You apply, you edit, you save through the normal permission-checked route.
Ask for a deeper data-flow section or a tighter overview and the full revised explanation is re-applied for review.
The design-document export assembles the full record, including the sign-off matrix, for reviewers and auditors.
The explanation lands in your editor on Apply and is saved by you. The PDF export is a deterministic report of the work, not a generated artefact.
Questions
Yes, if it has something real to write from. Write with AI works from your architecture diagram and an interview with the people who built the system, which is what separates a design document from generated filler. It describes what the diagram shows, asks focused questions about intent and trade-offs, and writes the structured explanation into your editor for review.
