123note is an online toolbox for useful everyday tasks. Each published tool has a clear purpose, instructions, limits and information about how it handles your data.

Browse the home page to find available tools. Open a tool page to learn what it does, what input it accepts and what result to expect. Tools are added after their functionality and content have been reviewed; a catalog preview is not a working tool.
Today, Text Compare is the published working tool. It compares two versions of plain text and lets you review or export the differences. More categories and tools may be added over time, but they are not available until they appear as published tools on the website.
Free use, accounts and future paid tools
Free tools work without signing in. You can save a published tool to your favorites on this device; that choice is stored in your browser. Where account features become available, Google will be the sign-in method for both Gmail and Google Workspace accounts.
If paid tools are introduced, their pages will show the applicable price, limits and purchase terms before checkout. A Google sign-in alone will not buy a tool or grant paid access. There is currently no paid tool or checkout on 123note.net.
Privacy and availability vary by tool
Check each tool page for its processing method, file limits and availability. Some tools can process data in your browser; a future tool may need server processing. We will explain that before you use such a tool. Offline use depends on the tool and on what your browser has already cached.
For example, Text Compare runs in your browser and does not upload or save the text you compare on our server. Its specific formats, limits and controls are described on its tool page.
