Visily is an AI-powered UI design tool for people creating app mockups and product designs without being designers.

More than 1,500 customizable templates cover mobile apps, web apps, websites, wireframes, and diagrams. Visily runs entirely in a browser, while its screenshot extension for Chrome, Edge, and Firefox converts captures into editable wireframes. A Figma plugin exports designs for further refinement, and integrations include Notion, Jira, Slack, and MCP. Slack can show link previews, comment notifications, and board updates. MCP connects designs with coding agents and is available on Pro, Business, and Enterprise plans. Starter is free at free, Pro costs $14 a month, and Business costs $29 a month billed annually.
