BLNG is an AI-driven creative suite for the jewelry industry, giving jewelers, designers, brands, and retailers tools to explore, refine, and present designs fast and without compromise. Its Design product turns sketches, doodles, photos, illustrations, or text prompts into photorealistic renderings on web and iOS; Studio transforms CAD models into market-ready marketing photos and videos at scale; and Retail enables live, made-to-order design in-store. BLNG is a Speedinvest portfolio company. BLNG publishes no developer program, but the web application is backed by three first-party REST APIs whose OpenAPI definitions are served publicly and unauthenticated behind Swagger UI on its own hosts — a Journey API for design journeys, prompts, image assets and 3D model generation, a User API for users, workspaces, invitations, organizations and subscriptions, and a Billing API for Stripe-backed products, checkout and subscription webhooks. All three authenticate with AWS Cognito bearer tokens issued at auth.app.blng.ai.
