Prompt template library editor
If you reuse prompts, you have probably lost a great one in a chat history.
This editor gives you a private, browser-local library: create templates, tag and
search them, mark fill-in variables with {{double_braces}}, and export the whole
set as JSON for backup or portability. It is a full CRUD tool — create, read,
update, delete — with no account and no server. Everything lives in your
browser’s localStorage, so it is yours alone.
How it works
You add templates with a name, a body, and optional comma-separated tags. The
editor scans the body for {{variable}} patterns and lists them so you know what
each template needs before use. A search box filters across names, bodies, and
tags. Selecting a template loads it for editing or deletion. Every change is
persisted to localStorage immediately, guarded so a corrupted or partial store
never breaks the tool. Export copies the whole library to your clipboard as JSON;
import takes that JSON pasted back in, merging by name.
Tips and examples
- Use variables for the parts that change.
Summarize {{document}} in {{n}} bullet pointsis reusable; a hard-coded version is not. - Tag by use case. Tags like
email,code-review, ormarketingmake a growing library searchable in seconds. - Export regularly. Clearing browser data wipes localStorage — a periodic JSON export is your backup.
- Keep names distinct. Import merges by name, so unique, descriptive names prevent accidental overwrites when moving libraries between machines.
