Pastukhov Note is one of the best cross-platform information management tools. The core idea is simple: notebooks that are hierarchies of Markdown-based documents. Unlike files in file systems, these documents act like folders, so that any document can have an unlimited number of children.
There are no strict rules or limits: you can organize your information in any way you want and change it anytime you need, keeping the complete history of edits. Unlike traditional desktop outliners, Markout enables you to link documents in many ways, including simple, Markdown and wiki links, add rich formatting and develop custom markup rules, manage tags, add images and files, tables and multi-level dynamic to-do lists, highlight syntax and embed external content. Sharing and publishing enables you to effectively collaborate with your team, partners and customers.
Pastukhov Note produces not just a static tree of documents, but an interlinked dynamic website with embedded rich and dynamic contents. You can add custom markup and footer code, JS and CSS scripts to all pages of your notebooks, easily include Markout documents or any other external HTML source into notes. It enables you to extend and override Markout features, embed external data and change its look and feel.
You can easily develop an internal storage of all important information and share it with your team. The all-in-one intranet portal. You can view and update it anytime you want and be sure that you will never lose any important fact or idea again.
It works great in any modern browser (including mobile ones, like Safari/Chrome on iOS and Android), even with a slow and unreliable Internet connection. It can work offline and synchronize when you need it, keeping all edits from all your team's devices in its history. There is a full-featured native Windows version with offline mode. I plan to release mobile and platform-specific versions in the next few weeks, starting with iPad/iPhone, then Android, then MacOS, then Linux.
There is an installed version for large teams and business which you can host locally, inside your intranet or even virtualize it. This way your data will never cross the boundaries of your corporate network.
