Signature is a free Chrome add-on developed by Cedric Amaya. It falls under the category of Browsers, specifically Add-ons & Tools. This program is designed for writers and editors who use Medium as their platform.

With Signature, you no longer have to manually copy and paste your signature or sign-off into your articles. Instead, you can simply type your blog's signature once, style it as desired, and save it. When you're ready to insert your signature, just click on the Medium "+" button and select the nib icon. Signature will automatically paste your saved signature for you.

Some key features of Signature include emoji support, similar to Medium's functionality. You can use a colon (":") followed by a few characters to bring up a range of options. Additionally, Signature offers native styling options such as bold, italics, code, and quotes. It also provides a toolbar button and a keyboard shortcut ("Alt + Shift + S") to open the settings page for easy access.
