An AI agent that drafts product requirement documents
An AI agent built by Leanware engineers that generates structured product requirement documents from a short feature or product brief. Internal proof point of how Leanware applies AI to document automation and product-management workflow.

The situation
Product managers spend a meaningful share of their week writing the same shape of document over and over: a PRD that describes the problem, the user, the solution shape, the success criteria, and the open questions. The format is well understood; the work that goes into producing each one is mostly translation from a few founder or PM sentences into the full document.
PRD Agent was started as an internal build to compress that translation. The brief was a tool, owned by Leanware, that took short feature or product input from a PM and produced a structured PRD on the other side, following industry-standard PRD templates rather than a generic LLM dump.
What we built
The build composition mirrored a real AI Product Engineering engagement: one senior full-stack engineer, one mid full-stack engineer, a product designer, and a product owner.
The user journey: a PM signs in (Google or Microsoft OAuth), provides the feature or product details (one or two paragraphs is enough), and the agent generates the PRD. The output follows a structured template the PM can review, edit, and download. The agent is configured around the PRD format the workspace standardized on, so the output is consistent across PMs rather than varying with whichever LLM prompt the PM happens to use.
Tech stack: React with Tailwind CSS on the frontend, Python with Flask on the backend, the OpenAI API for the generation, and Google and Microsoft OAuth for authentication. The fine-tuning around PRD templates is what differentiates the output from a generic LLM call.
PRD Agent also functions as a lead-generation surface. Users can request a Leanware project quote before they download the PRD, which means the tool that solves the workflow problem is the same surface that begins the conversation about building the thing the PRD describes.
Outcome
-
PRD generation reduced from hours to minutes for PMs using the tool
-
PRD output follows a standardized, reviewable, downloadable template
-
Lead-generation surface integrated into the download flow
PRD Agent compresses PRD authoring from hours to minutes for the PMs who use it. The tool is operational and runs as both a productivity tool for Leanware (and friendly users) and as a lead-generation surface that opens a real product conversation. Planned enhancements (per-industry templates, Jira and Confluence integration, AI improvements) sit on top of that working baseline.
