Textagram is a text-based diagram editor. You draw boxes, connectors, and text labels directly from the keyboard, whether you are in the browser or in the terminal.

It gives you WYSIWYG-style editing for plain-text diagrams. No DSL, no hidden metadata, no custom format: just text in, text out.

Everything you draw is made of Unicode box-drawing characters on a text grid. The result is a diagram that can live comfortably in Markdown, code comments, and version control.

Textagram supports three keyboard styles: vim (hjkl), game (wasd), and arrow keys. The interactive examples in this guide let you switch between them — click the style label in any animation to try a different one.
