If you're looking for something to replace Story Spec, Delibr is another possibility. Delibr is an information retrieval system that's geared to help product managers write product requirements documents (PRDs) more quickly. It uses dynamic templates and comes with a generative AI assistant to write high-quality documents, an AI copilot for reviews, and two-way Jira integration. Delibr is designed to free up time by automating the creation and maintenance of product documents, which makes it a good tool for product managers, developers and the rest of the development team.
Another option is Pipedream. Although it's geared more toward building elaborate applications with low-level code control and no-code interfaces, it also can be used to integrate with a broad range of services, including OpenAI. The service lets developers write custom logic with languages like Node.js, Python, Go or Bash and integrate with more than 2,100 APIs. Pipedream's flexibility and broad API support make it a good option if you need a full-fledged development environment alongside AI integration abilities.
