Frequently asked questions

What is “Formal Letter”?

Formal written communication: letters, certificates, cover letters, and memos. On papii this document is available as template generic.correspondence.formal_letter: a JSON Schema plus a deterministic PDF renderer, so the same data always produces the same document.

Can I generate a Formal Letter with AI?

Yes. chut.app — the AI back office papii powers — fills this template from a plain-language description: you describe the document in one sentence, the AI structures the data, papii validates it against the schema and renders the PDF. Developers can also call the papii API directly with structured JSON.

Is the Formal Letter template legally compliant?

This template is render-verified: its schema, sample data and PDF output are automatically tested on every release. It is published with status “ready”, meaning it has not yet been through papii’s final legal review. Where it references specific legislation, that is stated in the template description — always have a professional check documents with legal effect before relying on them.
