AI design tools have evolved from novelty to practical workflow — but no single tool covers the full design journey. Here's a stage-by-stage guide mapping Google Stitch, UX Pilot, Figma AI, and v0 to each step of the PM design workflow, from “I have an idea” to “engineering, here's what to build.”
Google Stitch for free ideation and multi-screen exploration. UX Pilot for wireframing with a UX lens (heatmaps, usability reviews). Figma Make (Figma AI) for high-fidelity, design-system-aware design. v0 for interactive prototypes and code-based handoff. Use 2–3 across the workflow rather than one for everything.
Before diving into stages, here's how the four AI design tools compare on the dimensions PMs care about most.
| Tool | Best design stage | Price | Standout feature |
|---|---|---|---|
| Google Stitch (Galileo AI) | Ideation & layout exploration | Free (Google Labs) | Gemini-powered multi-screen generation on AI-native canvas |
| UX Pilot | Ideation & wireframing with UX lens | Free tier; paid from ~$12/mo | AI UX design reviews + predictive heatmap generation + PRD import |
| Figma Make (Figma AI) | High-fidelity design & handoff | Included in Figma paid (~$12/seat/mo+) | Design-system-aware generation inside Figma + dev mode code gen |
| v0 (by Vercel) | Interactive prototyping & handoff | Free tier; $20/mo (Premium) | Production-ready React + Tailwind components with live URL |
The PM design workflow has five stages — ideation, wireframing, high-fidelity design, interactive prototyping, and design handoff. Each stage has different needs, and no single AI design tool excels at all of them. Here's how to map the right tool to each stage.
You have a feature idea or PRD and need to visualize what it could look like — fast, before investing in detailed design.
Free, Gemini-powered, multi-screen canvas. Generate 3–5 design directions from a PRD in minutes to show stakeholders. No cost barrier means you can explore freely. Just don't treat the output as final — it's a communication tool.
Import your PRD directly and generate UI informed by UX principles. The AI UX review flags usability issues during ideation, not after — so you explore directions that are usable, not just pretty. Best when you want design quality, not just visual quantity.
You've narrowed to 1–2 directions and need to refine the layout, information architecture, and user flow.
Predictive heatmap generation shows where users will likely look, helping you validate information hierarchy before investing in high-fidelity design. The AI UX review catches layout issues (crowding, unclear CTAs, poor visual flow) that a PM without design training would miss.
The multi-screen canvas lets you lay out a full user flow and see how screens connect. Free iteration means you can try multiple layouts quickly. Good for the 'does this flow make sense?' stage before committing to Figma.
The layout is validated and you need production-quality visuals that use your design system and component library.
Generates designs inside Figma using your actual component library, auto-layout, and styles. The output is immediately usable by designers — no export, no fidelity loss, no cleanup. If your team already uses Figma, this is the natural choice for high-fidelity work.
If you're early-stage or don't have an established component library, Stitch generates high-fidelity designs from scratch. The output looks polished but won't match your design system (because you may not have one). Good for greenfield projects.
Static screens aren't enough — stakeholders need to click through the flow and feel the interaction.
Generates production-ready React + Tailwind components — runnable code you can share as a live URL. Stakeholders click through a real interface, not a Figma prototype simulation. Best when the demo needs to feel like a product, not a mockup.
The March 2026 update added interactive prototyping on the AI-native canvas. Less production-ready than v0 but faster for quick 'does this interaction feel right?' checks. Free, so no barrier to trying it.
The design is approved and engineering needs to build it. How do AI design tools bridge the gap to code?
Figma AI's dev mode generates code snippets from design components, inspecting spacing, colors, and component structure for engineering. If your design lives in Figma, the handoff is built in. Engineering gets specs and starter code without manual annotation.
v0's output is already production-ready React code. If the prototype is good enough, engineering can use it as a starting point rather than rebuilding from a design file. Best for front-end-heavy features where the prototype IS the spec.

Rather than picking one tool, the most effective PMs use a small stack that covers the full workflow. Here's our recommended combination — all free or freemium, covering ideation through handoff:
Google Stitch (free)
Generate 3–5 design directions from a PRD in minutes. Free, so explore freely. Use for stakeholder 'here's what it could look like' conversations.
UX Pilot (free tier)
Validate layouts with predictive heatmaps and AI UX reviews. Catches usability issues before you invest in high-fidelity design.
Figma Make / Figma AI (~$12/seat/mo)
Generate designs inside Figma using your component library. The output is designer-ready — no export, no cleanup. This is where you invest budget.
v0 (free tier or $20/mo)
Generate clickable React components for stakeholder demos. When the demo needs to feel real, not just look real.
Figma AI Dev Mode (included in Figma paid)
Engineering gets specs, code snippets, and component structure from the Figma design. The bridge from design to code, built into your design tool.
Total cost for the full stack: $12–32/mo depending on which paid tiers you need. Compare that to the cost of a designer's time for the same output — the stack pays for itself in a single use. For free alternatives at each stage, see our free AI tools for product managers guide.

The best AI design tools for PMs in 2026 depend on the design stage. For ideation, Google Stitch (formerly Galileo AI) and UX Pilot generate UI from text prompts. For wireframing and layout, UX Pilot's AI UX review and predictive heatmaps add a usability lens. For design-system-aware generation, Figma Make (Figma AI) generates designs inside Figma using your component library. For interactive prototypes, v0 (by Vercel) generates production-ready React components. For design handoff, Figma AI's dev mode and code generation bridge the gap to engineering. Most PMs benefit from using 2–3 of these tools across the design workflow rather than one tool for everything.
Google Stitch is the rebranded version of Galileo AI, which Google acquired in May 2025. Stitch is a free Google Labs product powered by Gemini models that generates UI designs from text prompts. The March 2026 update added multi-screen generation, an AI-native infinite canvas, and interactive prototyping. It's free but experimental — Google Labs products can be sunset. For PMs, Stitch is best for ideation and stakeholder communication, not as a primary design pipeline. See our Galileo AI review for PMs for the full transition analysis.
Yes — AI design tools are specifically valuable for PMs who don't have a dedicated designer or need to communicate product ideas visually before design invests time. Tools like Google Stitch, UX Pilot, and v0 let PMs go from a text prompt or PRD to a visual mockup or clickable prototype in minutes. The output isn't a replacement for professional design — it's a starting point for communication, user testing, and stakeholder alignment. PMs should treat AI-generated designs as a draft that a designer refines, not a final deliverable.
Figma AI (including Figma Make) and Google Stitch serve different PM workflows. Figma AI generates designs inside Figma using your actual component library, design system, and auto-layout — so the output is immediately usable by designers without an export step. Google Stitch generates designs from scratch using Gemini and exports to Figma, but the export may require cleanup. Figma AI is best for PMs already working in Figma who need design-system-aware generation. Stitch is best for free, standalone ideation where you don't need design-system consistency. For most production PM workflows, Figma AI is the more practical choice.
UX Pilot is an AI design tool that goes beyond visual generation — it adds a UX research lens with AI-powered UX design reviews and predictive heatmap generation. When you generate a UI, UX Pilot can evaluate it for usability issues and predict where users will look, which is valuable for PMs who care about whether a design will actually work, not just whether it looks good. It also supports PRD import, so you can start from a product spec rather than a blank prompt. For PMs who want design informed by UX principles, UX Pilot is the strongest choice.
v0 (by Vercel) generates production-ready React + Tailwind components from text prompts — not design files, but runnable code. For PMs, v0 fits at the prototyping and stakeholder presentation stage: when you need a clickable, interactive prototype (not just a static mockup), v0 produces polished UI that you can share as a live URL. It's especially useful for demos where stakeholders need to feel the interaction, not just see a screen. v0 complements design tools like Stitch and Figma AI — use those for visual exploration, v0 for interactive validation.
