What is FirstVersion?

FirstVersion is an AI-powered tool designed to help product teams quickly generate the first version of a product specification document. Built by the team at Trickle, it solves the problem of starting from a blank page by using AI to draft a structured, comprehensive spec based on user input. The core capabilities include generating user stories, acceptance criteria, technical notes, and design considerations. It fits into the workflow of product managers, founders, and developers who need to rapidly prototype ideas and align their team around a shared vision. The tool leverages large language models to produce coherent and context-aware outputs, saving hours of manual writing. Users can iterate on the generated spec, refining it to match their specific requirements. FirstVersion is particularly useful for early-stage startups and agile teams that value speed and clarity in product development.
