Tenno

A live editable Markdown editor that lets you add cells like Excel. You can think of Tenno as a mix of Word and Excel with a touch of Obsidian, Markdown and JavaScript.

You can use all the power of Markdown to create nice looking documents, but here comes the kicker, you can easily add computations to your doc! And just like in Excel, you can simply add a cell, insert a formula and Tenno will figure out how to calculate everything for you.

Some other nice features:

• Live preview, edit your doc and see how it changes in real-time.
• Local execution, all the speed and privacy, no cloud interactions needed.
• Powered by JavaScript, world's most commonly used programming language.
• Call APIs to get JSON data.
• Charts included! No need to create a bunch of columns for every chart you want to make like you usually do in Excel.
