Ascii Math Unicode is a free Chrome add-on developed by Erik Brinkman. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

This tool allows users to easily convert AsciiMath expressions into their corresponding unicode equivalents. By highlighting any AsciiMath expression and clicking on the extension, users can instantly convert it into unicode. For example, an expression like "sum_(i=1)^n i^3=((n(n+1))/2)^2" can be converted into "∑ᵢ₌₁ⁿ i³=(ⁿ⁽ⁿ⁺¹⁾⁄₂)²". The converted expression can be copied and pasted, and it will work seamlessly in emails or messages.

Additionally, Ascii Math Unicode offers the convenience of converting text through a customizable shortcut, Ctrl+Shift+K, or by using the context menu.
