Tool overview

How Mention Extractor works

Mention Extractor provides a browser-local implementation for the documented workflow. It keeps the result visible, reviewable, and separate from the input while following PasteTidy's privacy and claims limits.

Mention Extractor workflows

  • Run Mention Extractor on pasted work data
  • Prepare local text or structured data for the next PasteTidy tool
  • Document a repeatable browser-local cleanup or conversion step

Use Mention Extractor locally

  1. Paste the source text or data.
  2. Review the local result generated in the output editor.
  3. Copy or download the result when it matches the intended workflow.

Mention Extractor assumptions and controls

  • This implementation uses a conservative local default for the documented task.
  • The input and output remain separate so destructive changes are reviewable.
  • No user content is placed in the URL, analytics payloads, or local history.

Mention Extractor example

Before
Ask @ana or @dev_team, not ana@example.com.
After
@ana
@dev_team

Mention Extractor limits and excluded claims

  • Do not imply compatibility with every platform's username rules.
  • Ambiguous or format-specific input may need manual review after processing.
  • This page intentionally avoids guarantees outside the visible local result.

Questions

Mention Extractor FAQ

Does Mention Extractor upload my input?

No. Processing runs locally in your browser and no upload endpoint is used.

What does Mention Extractor not verify?

Do not imply compatibility with every platform's username rules.

Can I use the output immediately?

Review the result first, especially when the source format is ambiguous or destructive cleanup was involved.
