2paste.io

2paste.io is a browser-based prompt workspace that keeps your reusable text in one organized library, swaps {{variable}} placeholders for real values on demand, and drops the finished text to your clipboard in a single click.

Automatic variable replacement

Write prompts with {{variable}} placeholders and the app turns each one into an input field, then substitutes your values the moment you copy.

Labels, projects, and filtering

Group prompts into projects and tag them with up to ten color-coded labels, then filter by label, project, date range, or starred status.

Keyboard-first workflow

Generate with the N key, jump around with Cmd/Ctrl+K, arrow through the list, and paste the result without leaving the keyboard.

Version history

Every edit is snapshotted and the last ten versions are kept so you can preview or roll back without losing earlier wording.
