Guides for every product live here. I'm Jack, an independent developer. I build small, focused SaaS products that each solve one problem well, ship them fast and keep improving the ones people use. Most of them work in the browser and let you start without an account. This site is the manual for all of them: what each product does, how to use it, and the specs and rules it follows. ### AI image and video tools **Album Art Creator** turns a song title, a genre and a few mood tags into a release-ready album cover in about a minute, checked against Spotify, Apple Music and distributor artwork rules. Start with the [album cover size guide for every platform](https://www.albumartcreator.com/blog/album-cover-size-guide) or open [Album Art Creator](https://www.albumartcreator.com/). ### Browser utilities **Timeline Visualizer** is a set of privacy-first travel map tools that run entirely in your browser, with nothing uploaded. You can [put your photos on a map](https://www.timelinevisualizer.net/photo-map/), mark the countries you have visited, or browse your Google Maps Timeline on the web. The Timeline video tool is built on the MIT-licensed open-source google-timeline-visualizer project, rebuilt for the web. See [Timeline Visualizer](https://www.timelinevisualizer.net/). ### Writing and creative tools **Elf Names Wiki** generates elven names with meanings and pronunciations across 11 subraces, with naming conventions from D\&D, The Lord of the Rings and The Elder Scrolls. Browse it at [Elf Names Wiki](https://www.elfnames.wiki/). ### Guides Step-by-step guides for each product live in the Guides section. New products are added here as they launch. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://jackcooperbuilds.gitbook.io/docs/readme.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
