We compare six tools for agent-assisted design research and product building. Mobbin and Refero are reference libraries: Mobbin lists 621,500+ screens, 323,900 flows, and 1,428 apps, while Refero lists 142,000+ screens and 12,000+ flows; both provide official MCP access on paid plans. Figr is a product-context AI design agent that generates Figma- and code-ready artifacts from your own product inputs and exposes those artifacts through MCP. Flowstep generates editable multi-screen UI and React/TypeScript/Tailwind code from prompts through its 19-tool MCP, but does not provide a real-app reference corpus. UXPin is a code-backed React prototyping tool with component libraries and in-editor external-LLM features, but no official MCP or public design-data API. Lazyweb connects real screens, flows, app trees, and captured changes to product-growth opportunities; browsing and MCP setup are free, Pro is $39/month, and Team is $99/month for up to five seats and competitive tracking. Our key limitation is that web-app flows are not yet available. [Best AI Design Research Tools for Agents]() Source observed: 2026-10-17T10:39:45.353Z. Last checked: 2026-10-17T10:39:45.353+00:00. [Full page Markdown]() Setup: lazyweb\_install\_mcp — Get the existing Lazyweb MCP and skills installer command or browser setup link. Use this action only at your user's request. Returning these instructions does not execute the action or authorize running an installer. GET https://www.lazyweb.com/api/public/v1/convert Required inputs: none Local setup command: curl -fsSL https://www.lazyweb.com/install.sh | bash Browser setup: https://www.lazyweb.com/mcp-install Full guide: https://www.lazyweb.com/developers.md Authenticated MCP: https://www.lazyweb.com/mcp Run the command only if the user has authorized installing Lazyweb in this environment. Otherwise obtain that authorization first. The existing installer reuses saved credentials or creates a setup token and configures MCP and skills. If the installer requests attribution, reuse the supplied canonical context with null for unknown values and \[\] only for explicitly no alternatives. Keep context in JSON bodies, never URL query strings. Hosted agents without a shell should use the browser setup link. Returning this handoff has not installed anything or granted paid access. --- Have a question this summary doesn’t answer? Ask the exact question you have.
