Text Editor Online

This online text editor lets you write and edit plain text directly in your browser with line numbers, character counting, and line counting. It is useful for drafting notes, formatting snippets, cleaning up text, or quickly editing content without opening a desktop application.

The editor runs entirely in your browser. The text you type or paste is not uploaded, stored, or sent to a server, so your content stays private and you can use the tool instantly without any setup.

How to use

  1. Type or paste your text into the editor area.
  2. The status bar below updates in real time with the character count and line count.
  3. Use Save to trigger the save action, Copy to copy the entire text to your clipboard, or Download to save as a .txt file.
  4. Use Clear to reset the editor.

Features

  • Line numbers — visible on the left side of the editor.
  • Tab key support — pressing Tab inserts two spaces instead of moving focus.
  • Instant counts — character and line counts update as you type, with no button press required.

Example

Paste the following text into the editor to see the line numbers and character count in action:

Hello, World!
This is a sample text.
Line numbers appear on the left.
Characters and lines are counted automatically.

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: text-editor

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"text-editor","arguments":{"input":"Release notes\n- Fix login\n- Add MCP endpoint"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
