PromptVault Pro: A Local-First Prompt Library That Stays Organised and Searchable

If you use generative AI regularly, your prompts tend to scatter. A few live in a chat history, a few are copy-pasted into a Notion page, and the one you need is rarely where you expect it. Finding it again takes longer than writing it did in the first place.

PromptVault Pro is described on the product page as "Your Prompt Library, Organised, Searchable, Shareable." It is a local-first prompt manager for power users who have outgrown a Notion page of copy-pasted text. This guide explains what the page says it does, how the listed features work together, and who it is likely to suit, using only the details from the product page.

What PromptVault Pro is

PromptVault Pro is presented as a prompt library in the Apps section of aeternusvita.io. The strapline on the page is "Your Prompt Library, Organised, Searchable, Shareable," and the supporting line calls it a local-first prompt manager for power users who have outgrown a Notion page of copy-pasted text.

That positioning is specific. The page presents it as the place where the prompts you already use are stored, found and reused, rather than as a model or chat app.

The page lists a Pro tier at $9.99 per month, shown as £7.99 per month per cycle with a "Buy for £7.99/mo" action. Check the product page for the current price in your currency before you buy.

Why a dedicated prompt library helps

A single page of pasted text works when you have a handful of prompts. Once you have dozens, the problems are predictable. You cannot filter by use case. You cannot tell which version you last improved. You end up duplicating prompts or rewriting them from scratch.

The product page frames PromptVault Pro around that gap. The phrase "who have outgrown a Notion page of copy-pasted text" points to someone who already prompts often and needs structure rather than another blank document.

The aim, as described, is to keep prompts tagged, versioned and searchable so you can locate the right one without scrolling through a long list.

How it works: tag, version and search across models and use cases

The product page groups the core behaviour in one line: "Tag, version, and search hundreds of prompts across models and use cases."

Tagging lets you label a prompt by what it is for, rather than where you happened to save it. The brief does not list example tags, only that tagging is part of how you organise prompts.

Versioning means you can keep the history of a prompt as you refine it. The brief does not describe how many versions are kept or how differences are shown, only that versioning is included.

Search is presented as working across the library, which matters once you have hundreds of entries. The page says you can search "across models and use cases," which indicates the library is intended for people who prompt more than one model and use prompts for different kinds of work. The brief does not name specific models.

Taken together, these three functions address the main friction of a flat list: you add structure with tags, you keep iterations with versions, and you retrieve with search.

How it works: one-click copy, variable substitution and team sharing

The second feature line on the page reads: "One-click copy, variable substitution, and team sharing built in."

One-click copy is the basic reuse step. Rather than selecting text and copying it manually, you copy the prompt ready to paste into the model you are using.

Variable substitution is the part that makes a prompt reusable. The brief states it is built in, but it does not describe the syntax or give examples. In practice, this kind of feature lets you keep a single template and fill in the changing part each time you use it, such as a topic, tone or audience. The page itself does not provide those details, so treat the presence of the feature as confirmed and the specifics as something to confirm on the product page.

Team sharing is also listed as built in. The brief does not describe how sharing is set up, whether it requires the same tier, or what permissions are available. The fact that it is mentioned indicates the library is intended for more than solo use, but the page does not detail the sharing mechanism.

Offline-first: your prompts live in your browser

The third feature line is distinct: "Offline-first — your prompts live in your browser."

Offline-first and local-first are both used on the page. Local-first appears in the short description, and offline-first appears as the feature heading. The explanation given is that prompts live in your browser.

That is a storage choice. It means the library is kept locally rather than only on a remote server. The brief does not describe sync, backup or export, and it does not state that prompts are encrypted or that they never leave the device. It only states that they live in your browser and that the design is offline-first.

For day-to-day use, this implies you can open and search your library without a connection, because the prompts are already there. If you work across devices or need a backup, check the product page for what, if anything, is provided beyond browser storage.

Who PromptVault Pro suits

The page is explicit about who it is for: power users who have outgrown a Notion page of copy-pasted text. That phrase does most of the audience work.

It is likely to suit you if:

• You have built up tens or hundreds of prompts and now spend time hunting for them
• You use prompts across more than one model or for more than one use case and want one searchable place
• You value tagging and versioning so you can keep iterations and find the right variant
• You want quick reuse with one-click copy and variable substitution inside a template
• You share prompts with others and want that sharing built into the library
• You prefer an offline-first approach where prompts live in your browser

It may be less relevant if you only prompt occasionally, keep a handful of prompts, or are happy with a simple note. In those cases a single document may still be enough. The brief does not position the product for children, so the general audience is adults managing their own workflow.

Pricing and where to find the current details

The brief shows two figures for the Pro tier: $9.99 per month and £7.99 per month per cycle, with a "Buy for £7.99/mo" action. Both figures appear in the text taken from the product page.

The brief does not list what is in a free tier, whether one exists, or what exactly the Pro tier includes beyond the features already named. It does not mention trial length, renewal terms, reviews, ratings, user counts, testimonials or dates. It also does not use "Coming soon" or "Notify me" language; it presents a buy action.
