How to install Prompt Vault, the AI prompt manager for ChatGPT and Claude.

Published 2026-05-19 · vøiddo

Prompt Vault keeps the prompts you actually reuse in folders, tags and search. If you keep the same launch prompts, support prompts, or writing prompts buried in notes, this is the shortest path from "I should save this" to "I can find it later". Firefox Add-ons is live now, Chromium browsers can load the public zip today, and the install path stays short enough to finish in one sitting.

best fit

If you keep the same prompts across ChatGPT, Claude, client work, support, or content ops, Prompt Vault saves the part that burns time: digging through old docs, half-finished snippets, and copied launch replies.

Firefox live now, Chromium zip live now.

Use Firefox Add-ons for the quickest route, or load the public zip unpacked in Chromium if that is your browser today. If you want the comparison first, keep the install guide open in another tab and then decide. The shortest install path is still a real install path.

What Prompt Vault actually does

The extension gives you a local prompt library with folders, tags, search, and optional public sharing. Save the prompt once, file it by workflow, and find it again without opening a notes app, a bookmark folder, or a second chat tab.

install path

two routes to the same library

Firefox users can install from the live add-on page. Chromium users can download the public zip and load it unpacked right now.

  1. Install from Firefox Add-ons, or download the public zip if you are on Chromium.
  2. For Chromium: open chrome://extensions, enable Developer mode, click Load unpacked, and choose the extracted Prompt Vault folder.
  3. Save 3-5 prompts you actually reuse: launch post, support reply, meeting agenda, launch checklist, client update, or whatever shows up every week.
  4. If the manual route gets noisy, open the support page for the browser-specific fix.

what it is for

  • folders for workflow
  • tags for reuse
  • search when the library grows
  • public sharing when you want to publish a prompt
public example

Before you install, open a real public collection to see the payoff. The launch ops workflow pack shows how a reusable prompt becomes a crawlable page with a clean URL, and the collections index shows the rest of the public library.

What happens after install

Open the extension, save the prompts you reach for repeatedly, and keep them in a structure that matches your work instead of your browser history. When the library gets bigger, use search. When you need to share a prompt with a teammate or client, publish it instead of pasting the same text into three different docs.

Prompt Vault works especially well for launch prompts, support replies, research checklists, and the small repeatable snippets that keep leaking out of notes apps and chat drafts.

Prompt Vault vs scattered notes

find the right prompt fast search by folder, tag, or title possible, if the note is labeled well only if you remember where it lives
keep versions separate yes usually manual no
share a prompt cleanly yes, when you choose possible, but messy not really
works inside the browser workflow yes not by default not by default

Why this is a better install path than waiting

The browser-store route is useful when it lands, but you do not need to wait for it to get value out of Prompt Vault. The live Firefox listing and the public Chromium zip already give you a real install path today. If Prompt Vault becomes the place where your reusable prompts live, the next time you need one the answer is a search, not another scratch note.

Frequently asked questions

Do I need to wait for another store review?

No. Firefox Add-ons is live now, and Chromium browsers can load the public zip today.

Does Prompt Vault keep my prompts local?

Prompt Vault starts local-first in your browser. You keep the library organized there and only publish prompts when you choose to share them.

Is there a free tier?

Yes. Prompt Vault has a free tier for up to 20 personal prompts, plus paid plans for heavier use and sharing.

Who is this best for?

People who reuse the same prompts across ChatGPT, Claude, client work, support, content ops, and team playbooks.

What if the zip or install page blocks?

Open the support page. It breaks the install flow down by browser and gives you the fastest fallback route.

Prompt Vault also lives on the main product page at extensions.voiddo.com/prompt-vault/, and the compare page explains why a real prompt library beats scattered snippets when you want to find the same prompt again tomorrow.
