If you’re sick of flow charting in Vizio (or whatever) and are feeling nostalgic for the good old days of ASCII art, ASCIIFlow can solve both your problems by letting you make text-based flow charts right in your web browser.The tools are simple and it’s very easy to use. Just draw boxes and arrows where you want them, then add text with the type tool (just remember to press enter when you’re done typing or it won’t save). If you need more room, you can click the Add Row and Add Column buttons to increase the width and height (respectively) by one character at a time.
When you’re done, you can export as text or HTML. It may not be your go-to flow chart app for most things, but it is actually a usable tool—especially when you can’t work with images—and it’s a lot more fun.
