What is Build?
Build is the core experience in Create mode, where you and your team visually bring product ideas to life.
It’s not just a wireframing canvas — it’s a fully connected environment where your prototype always reflects your design system, and collaboration is built in.
In the Build section, you can:
- Turn ideas into interactive flows using real components and tokens
- Use natural language to accelerate prototyping
- Collaborate with teammates without stepping on each other
- Share prototypes with stakeholders for feedback and alignment
How to use it
Build with AI
- Describe what you want to create — a new flow, page, or feature — and AI instantly builds it using your connected design system
-
You can start from a blank project, mention a document, or import from Figma.
AI transforms your description into an interactive prototype you can immediately edit, style, and iterate on.
Chat with your team
- Collaborate directly in the prototype with built-in chat.
- Ask for changes, discuss ideas, and give feedback in real time — all in context, without switching tools.
- Every message is linked to what’s visible on screen, keeping discussions focused and actionable.
Threads
- Explore ideas safely in separate threads
- Each collaborator can work independently, experiment freely, and merge changes later without affecting others’ work.
Insert from Figma (soon)
- Import a specific frame or flow from Figma to continue building directly in Portal.
- You can stay connected to your design system and make imported screens interactive without manually recreating them.
Attach files
- Attach relevant materials — screenshots, documents, or research notes — directly to your prototype.
- Everything your team needs for context and decision-making stays in one place.
Mention a document
- Prototype directly from a document reference.
- Mention a PRD, one-pager, or spec, and Portal automatically generates a prototype based on the document’s description and context.
Share your prototype
- Generate a share link to preview or comment on your prototype.
- Stakeholders can view, navigate, and give feedback without needing edit access — making reviews fast and transparent.
