The record format for your business documents
slidelang and doclang compile plain text — written by humans, systems, or AI agents — into a versioned semantic AST. What ships is traceable, searchable, and validated. Not just generated better.

The DSL is one authoring interface — a human- and LLM-friendly way in. The real contract is the versioned AST underneath it: a stable, semver'd intermediate representation that any tool, agent, or renderer can consume. Today an AI writes .slidelang/.doclang source; tomorrow it can emit validated AST directly, or a third-party tool can produce either format from JSON, a spreadsheet, or a CRM.

llms.txt →Two Modes: Flexible and Strict
Because ZiraDocs serves both the messy drafting phase and the rigorous publishing phase, the compiler operates in two flavors:
Flexible Mode
Permissive parsing designed for AI agents and rapid human drafting. It tries its best to render your intent without failing on minor syntax omissions.
Strict Mode
Unforgiving validation designed for publishing and compliance. If the AST doesn't perfectly match the schema, it fails the build — whether that's a GitHub Action, a Node service, or a button in a UI.
Use Cases
Pharma & Compliance (MLR)
(Strict Mode) For highly regulated industries. Enforce Medical, Legal, and Regulatory (MLR) rules wherever documents are published. Every claim is traced to its substantiation, every document meets accessibility standards (PDF-UA), and what doesn't pass the rule doesn't compile.
System-to-Document API
(Strict Mode) Generate reports, pitch decks, or invoices directly from your database, CRM, or internal APIs. Emit the validated JSON AST natively and compile to PDF or PPTX from wherever you invoke it — a service, a backend, or a script — with absolute structural certainty.
Drafting with ChatGPT or Claude
(Flexible Mode) Hook our MCP server into Claude Desktop, or paste our llms.txt into ChatGPT. Have the AI draft entire decks or documents from your notes. Flexible mode ensures the agent's output renders gracefully even if the syntax isn't flawless — it's the on-ramp to strict mode, not the destination.
A tool improves one document. A platform governs an organization.
Everything above is free and open, forever, by construction. When one team becomes twenty, "is this valid slidelang?" becomes "does this comply with our policy — and can we prove it to an auditor?" That's a different product. A standard that charges for the format isn't a standard, so we never charge for the format — format rules are free, your rules are the paid layer.
