Fine Structure is an AI software-building platform. Describe what you need in plain language and it generates a complete, working product: pages, data models, authentication, integrations, and publishing. Beyond building, it runs autonomous AI agent teams for your business and maintains a knowledge brain over all your data.
Generate complete applications, SaaS products with subscription billing, CRMs, dashboards, client portals, booking systems, internal tools, and landing pages. Every app is real, editable code that you own, with versions, previews, a testing agent, custom domains, and one-click publishing.
Deploy a manager agent that delegates to specialist agents for sales, support, and operations. Agents work 24/7 across WhatsApp, web chat, and email, follow your guardrails, ask for approval when needed, and report everything they do.
A shared knowledge base over your documents, conversations, meetings, and app data. Both your apps and your agents answer with grounded facts from your own business instead of guessing.
Fine Structure is agent-native and self-serve: sign up free (no credit card), create a scoped API token at finestructure.ai/api-keys, and connect. A sandbox environment is available for safe experiments, and the free tier lets you build real apps before paying.
The free plan includes daily AI generations at no cost, with no credit card required. Paid subscriptions add higher limits, more credits, and advanced features. See pricing for current plans.
