Fine Structure: describing software in plain language and getting a working product

Skills change how an agent behaves inside a conversation. Fine Structure is what happens when the same idea is applied to a whole product: you describe what the software should do, and the platform generates the pages, the data model, the authentication, the integrations and the publishing step, as code you own.

What it actually produces

The output is a working application rather than a scaffold: pages, a data model, authentication, integrations and a one click publishing step. The code is editable and versioned, every file change is saved as a version that can be restored, and the code belongs to the account that generated it.

  • SaaS products with billing, CRMs, dashboards, client portals and booking systems.
  • Landing pages and marketing sites, published to a custom domain.
  • Internal tools that replace a shared spreadsheet.

Agent teams, not a single assistant

The second half of the platform is autonomous agents that run around the clock on WhatsApp, web chat and email. A manager agent delegates to specialists for sales, support and operations, inside guardrails that set what each one may do. It is the same separation this site's combinations page describes for skills, applied to agents that are running.

The shared knowledge base

Underneath both sits a shared knowledge base, the business brain, built from documents, conversations, meetings and the data inside the apps themselves. Apps and agents answer from it, so a price or a policy comes from the owner's own material rather than from the model's general knowledge.

How the parts fit together

Generating the software is the first step. The platform also keeps the operating layer around it in one account: the knowledge base, the agents, the guardrails that limit them, and publishing to a domain. A change to the app, to the data or to an agent's instructions is made in the same place.

For people who work with agents already

There is programmatic access as well as an interface: an MCP server at https://finestructure.ai/api/mcp, a REST API with an OpenAPI 3.1 specification, and self serve tokens. Claude connects to the MCP server over OAuth 2.1, and the Claude Code plugin registers the same server. For someone who writes skills this is the relevant detail: the platform can be driven by an agent, so an app built there can also be changed and operated by the agents already in use.

Questions people actually ask

Is there a free plan?
Yes. The free tier includes daily AI generations and does not require a credit card. Paid plans raise the limits.
Who owns the code it generates?
You do. The output is editable and versioned code rather than a locked template, and it can be published with one click.
How is this different from a website builder?
A website builder produces pages. This produces an application with a data model, authentication and integrations, and it can run agent teams on WhatsApp, web chat and email alongside it.
Can an agent use it directly?
Yes, through the MCP server at https://finestructure.ai/api/mcp and a REST API described by an OpenAPI 3.1 specification, so an agent can drive it as well as a person.
