This looks really cool! However, as an Evernote and Notion customer (yes, I use and pay for both), I would love to know what would make me switch tools, or add this to my subscriptions?
The key difference is the way how data is structured. I think it's easier to navigate and use the data on a board than within a document. However, as a drawback, the amount of information on the board is more limited than in the document for comfortable usage. That's why I believe Boardist won't work well enough for huge volumes of data and big teams.
We are also more focused on personal needs. For example, we already have an extension for bookmarks. Our next steps will include providing content scrappers and more productivity tools.
My goal is to provide the best experience with data organization. Don't hesitate to try Boardist and hope you will enjoy using it. Your feedback is highly appreciated.
