2paste.io

The tool provides a web‑based library for storing AI prompts and inserting variable placeholders that can be filled in before copying. Users can create a prompt, add notes, assign color‑coded labels and group them into projects, then retrieve any prompt via search, filtering, or keyboard shortcuts. When a prompt contains placeholders such as {{variable}}, the interface presents input fields, updates a live preview as values are entered, and copies the fully rendered text to the clipboard with a single click.

It is aimed at developers and other power users who repeatedly use the same prompts for tasks like email drafting, code review, or documentation. The service emphasizes rapid, keyboard‑first interaction, version snapshots for each edit, and the ability to organize prompts by label, project, or usage metrics.

Distinctive aspects include automatic detection of {{variable}} syntax, real‑time variable substitution, a built‑in version history limited to the ten most recent revisions, and a command‑palette style navigation that allows creation and editing without mouse interaction.
