Collaborative interface and vector design tool
Figma is a browser-based design platform combining vector editing with real-time collaboration. It has expanded illustration and asset libraries that overlap with Illustrator use cases.
UI/UX design and prototyping tool
Adobe XD offers vector-based UI design, prototyping, and voice interaction design integrated with Creative Cloud. It runs on both Mac and Windows unlike Sketch.
Design and publish real websites with AI
Framer lets designers create high-fidelity interfaces and publish them as live, responsive websites, with Framer AI generating layouts from prompts. It merges design and production in one tool.
Turn prompts and sketches into UI designs
Uizard generates editable app and web screens from a text prompt, screenshot or hand sketch. It is aimed at fast concepting rather than pixel-perfect final design.
AI-assisted interface design
Figma AI adds prompt-based layout generation, smart rename, content fill and visual search to the collaborative design tool designers already use.
