What does Text Editor Online do?

Text Editor Online provides a browser-based scratchpad with line numbers, word wrap, and character counting.

  • Primary use: Text Editor Online provides a browser-based scratchpad with line numbers, word wrap, and character counting.
  • Key technical fact: Line-oriented editing is useful because many code reviews, logs, and compiler errors reference exact line numbers.
  • Practical check: Review Unicode, whitespace, line break, and punctuation behavior before treating the output as production text.

Edit plain text with line numbers and live counts

Text Editor Online is a local scratchpad for plain text, snippets, logs, notes, and quick cleanup work. Line numbers stay visible while you type, so you can reference exact lines from stack traces, compiler output, CSV rows, config files, or review comments.

The editor is intentionally simple: it does not format rich text, execute code, or auto-save drafts. It keeps your text in the browser page, supports word wrap for long lines, and shows live character and line counts before you copy or download the result.

How to use

  1. Type or paste your text into the editor area.
  2. Use the line numbers to locate errors, log entries, copied rows, or sections you want to discuss.
  3. Check the live character count and line count before reusing the text.
  4. Copy the whole editor contents, download a .txt file, or clear the editor when you are done.

Example

Paste a small snippet, verify its line positions and counts, then copy or download the exact plain-text result:

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.
