Introduction
CoQuill is a document assembly tool built on Claude Cowork. It is similar to traditional document automation platforms — docassemble (which this project takes a lot of inspiration from), HotDocs, Documate — but approaches the process using AI first. The result is a tool that is much simpler: a conversational interview driven by Claude, producing completed documents from plain templates. See How CoQuill Compares for a detailed breakdown.
With CoQuill you can:
- Create guided interviews to create contracts and documents using simple templates
- Use AI to draft questions and plan the interview process
- Render documents in several format by using AI
The problem with traditional document assembly
Section titled “The problem with traditional document assembly”Traditional tools require you to:
- Learn a proprietary scripting language
- Build a web-based interview form by hand
- Host and maintain a server
- Train non-technical users on complex software
CoQuill’s approach: write a template in Word, HTML, or Markdown, add {{ variable_name }} placeholders, and let Claude handle everything else.
How it works
Section titled “How it works”1. You write a template
Add a .docx, .html, or .md file to templates/, using Jinja2-style placeholders wherever you need dynamic content:
This Agreement is entered into between {{ client_name }} ("Client")and {{ consultant_name }} ("Consultant"), effective {{ effective_date }}.2. Claude interviews you
Tell Claude: “Prepare meeting notes”. Claude finds your template, analyzes it for variables, conditional sections, and loops — then walks you through a natural conversation to collect all the values.
Let's prepare the Meeting Notes. I'll start with the meeting details.
What is the title of this meeting?> Q1 Sprint Retrospective
When was the meeting held?> 28 February 20263. You get a completed document
Once confirmed, the document is rendered and saved to output/. Docx templates produce Word documents and, when Microsoft Word or LibreOffice is available, a PDF too. HTML templates always produce both HTML and PDF. Markdown templates produce a .md file with an optional PDF. A transcript of the interview is saved alongside the output for reference.
What you can build
Section titled “What you can build”CoQuill works for any document that follows a consistent structure with variable content:
- Legal agreements — NDAs, consulting agreements, service contracts, leases
- Business documents — proposals, invoices, statements of work
- HR documents — offer letters, employment agreements, onboarding forms
- Compliance documents — privacy notices, terms of service, consent forms
What CoQuill is not
Section titled “What CoQuill is not”CoQuill is not a general document editor. It is not a CMS, a form builder, or a word processor. It is a fill-in-the-blanks engine: the template author controls the structure, the AI collects the values, and the output is a completed instance of that template.
