2paste.io

2paste.io is a lightweight web app for people who live in chat windows and API consoles all day. Instead of scrolling back through old conversations or half-written notes to find that one reliable prompt, you store each template once, give it a name, and tag it so it can be found again in seconds. There is nothing to install; the whole workspace runs in a browser tab and syncs to your account.

The feature that does the heavy lifting is variable substitution. Any {{placeholder}} you type inside a prompt is detected automatically and rendered as an editable field. Fill the fields once and the preview updates live, so you can confirm the final wording before you paste it into ChatGPT, Claude, an email client, or anywhere else. A single Replace & Copy button applies every substitution and puts the result on your clipboard.

Around that core loop the app adds the housekeeping you would otherwise do by hand: color-coded labels, project grouping, starred favorites, full-text search, a Cmd/Ctrl+K command palette, and ten-step version history. The service is currently free under a Founder's Access program, with the stated intent that early users keep feature parity if paid plans are introduced later.
