Why Concept Sandbox
Built for creators who ship alone.
One connected system
Ideas, PRDs, and prototypes live together. No more scattering your work across Notion, Google Docs, and Figma.
AI at every step
Claude, GPT, Gemini, and more work alongside you — extracting structure from chaos, generating PRDs, critiquing ideas. Pick the best model for every task.
Zero team overhead
No sprint planning. No permission matrices. Just you, your ideas, and the shortest path to a working prototype.
Features
Everything you need. Nothing you don't.
Built specifically for solo creators who want to move fast without the bloat of team collaboration tools.
AI Brain Dump
Type your messy, half-formed thoughts. AI automatically extracts a clean title, concise summary, and searchable tags from the chaos.

Testimonials
Loved by independent builders.
“It replaced my messy Notion docs and 5 different Figma files. Now my ideas actually turn into code.”
“The AI PRD generator alone saves me hours of staring at a blank page. The UI scaffolding is just magic.”
“Finally, a tool built for the solo workflow. I went from a vague idea to a deployed prototype in one afternoon.”
