Keep My Prompts Alternatives for Prompt Storage

TL;DR: A good Keep My Prompts alternative depends on why you're leaving. Keep My Prompts is cheap, encrypted and exports cleanly, but its free plan is small and its own pages disagree on the cap. For more free storage, try MuseBox. For a sidebar library, Gud Prompt. For local-only storage, Espanso. For better prompts, Prompt Architects.

People looking for a Keep My Prompts alternative usually arrive with one job in mind: somewhere reliable to keep the prompts they have already written. This page is for that reader. It compares storage first, and treats scoring, optimizing and generating as extras.

One correction before we start. It is tempting to describe Keep My Prompts as a simple storage locker, and our own content plan did exactly that. It is not. Checked on 16 September 2026, the product scores prompts on six criteria and rewrites them with an optimizer. So the question is not storage versus smart tools. It is which tool stores your prompts on the terms you want.

What is Keep My Prompts, and what does it do well?

Keep My Prompts is a web app, made in Italy according to its footer, for organizing, versioning and improving AI prompts. Its homepage headline is "Stop rewriting the same prompts." and the product backs that up with more than a folder system.

What it offers, per its own pages on 16 September 2026:

• Categories, tags and search. Color-coded categories and instant search.
• Version history on Pro, with snapshots you can compare and restore.
• Prompt Score, which rates a prompt from 1 to 5 across six criteria: clarity, context, structure, role prompting, few-shot examples and chain-of-thought.
• Deep Optimize, which the homepage says "rewrites 3 variants and auto-tests each one."
• Sharing by secure link, plus team plans for 5 to 20 members.
• Encryption and export. The site says prompt content is encrypted with AES-256-GCM before storage, and it offers "Full export in one click" as JSON.

The pricing is low. The pricing page title lists Free, Pro at €1.99 a month and Ultimate at €4.99 a month. Those plan cards render with JavaScript, so we took the figures from the page's own title and meta description rather than from the cards.

Honestly, that is a strong package for the price, and the JSON export means you are never locked in. If it already works for you, the rest of this page is only worth reading if one of the problems below applies.

Why look for a Keep My Prompts alternative?

The most common reasons fall into four groups.

The free plan is small, and the number is unclear. The pricing page's meta description says "Start free with 20 prompts and AI scoring." The FAQ page says "The Free plan offers 10 prompts and 3 categories." Both were live on 16 September 2026. Either way, a free library of 10 or 20 prompts fills up quickly for anyone who uses AI daily.

It lives in a separate tab. On its homepage and pricing page we found no mention of a browser extension. The workflow is copy from the web app, paste into ChatGPT or Claude. The homepage says you can find and copy a prompt in about two seconds, which is quick, but it is still a tab switch.

Prices are in euros. For buyers outside the eurozone, a bank may add a conversion fee. That is minor at €1.99, but worth knowing for team plans.

You want storage without the optimizer. Some people only want a vault. Scoring and optimizing are useful, but if you never touch them, a simpler tool with a bigger free tier may suit you better.

Which tools are the best Keep My Prompts alternatives for storage?

Short answer: MuseBox for free capacity, Gud Prompt for a sidebar, PromptHub for technical teams, prompts.chat or Espanso if you want to own the data, and Prompt Architects if you want storage tied to prompt improvement. Details below, all checked on 16 September 2026.

MuseBox: the largest free allowance we found

MuseBox describes itself as a personal prompt library with folders, tags and a community feed. Its free Starter plan lists 250 prompt storage slots, two AI enhancements per day and five saved versions per prompt. Standard is $6 a month (500 slots, private prompts, CSV upload) and Pro is $12 a month (unlimited slots), as shown on its monthly pricing.

It also has a Chrome extension that inserts prompts into ChatGPT, Gemini and Claude, and CSV import for moving an existing archive.

The catch: on the free plan, private prompts are not listed; they appear from Standard up. Check what "private" means for your prompts before storing anything sensitive on Starter. MuseBox is also built around a public community feed, which some people enjoy and others find distracting.

Gud Prompt: a library that sits beside the chat

Gud Prompt pairs a web library with a Chrome extension that shows your prompts in a sidebar next to ChatGPT, Claude and Gemini. Its pricing page lists:

• Free: bookmark up to 20 prompts, save 5 of your own.
• Pro: $4.95 a month, with unlimited prompts, version history on every prompt, up to 10 collections and up to 50 AI prompt generations.
• Teams: $99 a month for five full seats, with role-based access.

The catch: the free plan saves fewer of your own prompts than Keep My Prompts. Gud Prompt's free tier is for browsing its public library, not for storing yours.

PromptHub: storage with versioning for technical teams

PromptHub is aimed at teams that build with LLMs. Its pricing page lists a Free plan with unlimited public prompts but no private prompts, a Pro plan at $12 a month on monthly billing with unlimited private prompts and full API access, and a Team plan at $20 per user per month. A yearly toggle shows lower prices.

The catch: if you want private storage, the free plan does not cover you, and the tool is more technical than most people need for everyday ChatGPT prompts.

prompts.chat, self-hosted: storage you run yourself

prompts.chat, formerly Awesome ChatGPT Prompts, is a free, open-source prompt platform. Its homepage offers a private server you can deploy yourself, which means your prompts sit on infrastructure you control. The code is MIT-licensed and the public prompt content is CC0.

The catch: you have to host it. That is easy for a developer and a real barrier for everyone else.

Espanso: plain local storage

Espanso is a free, open-source text expander under the GPL-3.0 licence. It is not a prompt manager, but a folder of Espanso match files is a perfectly good prompt store: local, plain text, easy to back up, and you can expand any prompt by typing a short trigger.

The catch: no interface for browsing, no sharing, and no sync unless you arrange it yourself.

Prompt Architects: storage tied to generation and enhancement

This is our product, so read critically. Prompt Architects is a Chrome extension that opens as a sidebar inside ChatGPT, Claude and Gemini. Its main job is turning a rough request into a structured prompt with built-in AI, with no API key needed. Storage is part of it: Pro ($4.99 a month at the time of writing) saves up to 50 prompts with tags and search, and Advanced ($9.99 a month) makes the library and prompt history unlimited. The Team plan shares one library across 2 to 20 teammates.

The catch, stated plainly: the free plan does not save prompts. It gives you five enhancements per day, according to our FAQ page, but a library needs Pro. And Pro's 50-prompt cap is lower than Keep My Prompts Pro, which is unlimited at €1.99. If cheap unlimited storage is the only thing you want, Keep My Prompts wins that comparison.

Where we fit is the reader whose stored prompts are not very good yet. Storage plus a rewrite step inside the chat window saves more time than a bigger vault.

How do the alternatives compare on storage?

Here is the storage picture on one page. Prices are monthly, at the time of checking.

A note on the version history row: the Prompt Architects pricing table does not list prompt version history as a feature, so we mark it absent rather than implying it. Prompt history, a log of your enhancements, is a different thing: 100 entries on Pro, unlimited on Advanced.

Do you need prompt scoring, or just storage?

For most people, storage matters more at first and quality matters more later. A score is only useful once you have prompts you reuse often enough to care about their structure.

Keep My Prompts' six criteria are a sensible checklist. Clarity, context, structure, a role, examples and step-by-step reasoning are the same levers most prompt guides teach, including our own prompt engineering cheat sheet. What a score cannot tell you is whether the prompt produced a good answer for your task. A long, well-structured prompt can still miss the point.

So treat any scoring or optimizing feature, theirs or ours, as a nudge rather than a grade. A practical test before you pay for one:

1. Pick three prompts you use every week.
2. Run each through the tool's scorer or rewriter.
3. Send the original and the rewritten version to the same model, in fresh chats.
4. Keep whichever output you would actually ship.

If the rewrite wins two out of three, the feature is earning its place. If not, a plain storage tool with a bigger free tier is the better buy, and that points you to MuseBox, Espanso or a self-hosted library rather than to any optimizer.

How do you move your library out of Keep My Prompts?

Keep My Prompts makes this easy, which is to its credit. Its site describes a JSON export from Settings, including categories and notes.

Use this sequence:

1. Export to JSON from Settings before you change or cancel any plan.
2. Keep the raw file somewhere outside every prompt tool. That file is your backup no matter what you choose next.
3. Convert if needed. MuseBox imports CSV. A short script turns the JSON into CSV, as below.
4. Prune while you move. Delete prompts you have not used, and rewrite the ones you keep. Our guide to organizing 1,000+ ChatGPT prompts has a tagging scheme that holds up.
5. Run both tools for a week before deleting the old account.

We have not seen Keep My Prompts' exact JSON field names, so adjust the keys in this sketch to match your file:

import csv, json

# Adjust these key names after opening your own export file.
TITLE, BODY, CATEGORY = "title", "content", "category"

with open("keepmyprompts-export.json", encoding="utf-8") as f:
    data = json.load(f)

prompts = data if isinstance(data, list) else data.get("prompts", [])

with open("prompts.csv", "w", newline="", encoding="utf-8") as out:
    writer = csv.writer(out)
    writer.writerow(["title", "prompt", "category"])
    for p in prompts:
        writer.writerow([p.get(TITLE, ""), p.get(BODY, ""), p.get(CATEGORY, "")])

print(f"Wrote {len(prompts)} prompts to prompts.csv")

What should you look for in any prompt storage tool?

Before you pick, check these five things on the vendor's own page, not a review:

1. The real free cap. Read the pricing page and the FAQ. As Keep My Prompts shows, they can disagree.
2. Export format. If you cannot get your prompts out in a file, you do not own them.
3. Where the data sits. Cloud tools sync; local tools keep data on your machine. Pick the risk you prefer.
4. Private versus public. Community-first tools may treat free-plan prompts differently from paid ones.
5. How the prompt reaches the chat. A sidebar or shortcut beats a separate tab if you use AI all day.

If you're weighing several extensions at once, our Promptly alternatives and AIPRM alternatives guides use the same method. And if a free tool is a hard requirement, see our list of free AIPRM alternatives that don't gate the good prompts.

Which Keep My Prompts alternative should you choose?

• You want the most free storage: MuseBox.
• You want prompts in a sidebar next to the chat: Gud Prompt or Prompt Architects.
• You build with LLMs and need API access: PromptHub.
• You want to own the data completely: self-hosted prompts.chat or Espanso.
• You want your stored prompts to get better, not just safer: Prompt Architects.
• You want cheap unlimited storage with scoring and clean export: stay with Keep My Prompts.

That last option is a real one. For €1.99 a month, Keep My Prompts gives unlimited storage, version history and an easy exit. Most people who leave do so because of the small free plan or the separate tab, and both are easy to test before you move anything.
