What it solves

SlideRule addresses the high cost and long timelines associated with product development. Instead of spending weeks on PRDs and team alignment only to find a direction is wrong, it allows users to turn a one-sentence idea into a fully rehearsed, runnable product plan in the time it takes to drink a coffee, reducing sunk costs and accelerating validation.

How it works

The system uses a V5 rehearsal engine that processes a user's intent through a multi-loop reasoning process using a capability pool (including risk analysis and evidence search). It generates a "five-system model" consisting of a data model, RBAC (Role-Based Access Control), workflows, pages, and AIGC capabilities.

Crucially, the engine employs "evidence trust gates"—deterministic checks that artifacts must pass before they are accepted. A product is only "shipped" to the browser live runtime when a "publish closure" (6/6 evidence) is achieved. The resulting JSON schema is then rendered into an operable system in the browser with zero backend required for the preview.

Who it’s for

It is designed for product managers, entrepreneurs, and developers who want to rapidly prototype business structures and validate product ideas through executable specifications rather than static documents.

Highlights

• Evidence-Gated Workflow: Prevents AI "hallucinations" of completion by requiring artifacts to pass deterministic gates.
• Browser Live Runtime: Renders the generated business model into a functional app preview with live RBAC, workflow monitoring, and data editing.
• Five-System Model: Generates a comprehensive business structure including data models, permissions, and operational workflows.
• Zero-Install Demo: Offers a static workbench where users can watch real rehearsal playbacks or use their own API keys to run new rehearsals.
