The best prompt manager for Windows is the one that still finds the right prompt, in the right version, with its reference images attached, six months after you saved it. 77Fox is a free Windows desktop app whose prompt library is built around exactly that: categories, per-prompt version chains, automatic snapshots, up to 15 references per version, one-click translated versions and AES-256-GCM encrypted sync into your own Google Drive. It is one of four reasonable approaches, and this guide lays out the criteria so you can judge each of them, including 77Fox, on evidence rather than marketing.
Rather than ranking named products whose feature lists change monthly, the comparison below groups tools by approach. If you evaluate a specific product, run it against the checklist in the last section.
The four approaches
| Approach | Typical examples | Strength | Weakness |
|---|---|---|---|
| Notes app | Notion, Obsidian, OneNote, plain text files | Already installed; good for long context around prompts | No prompt-level versions, no attached reference media per version, navigation between you and the text |
| Chat history | The history panel of ChatGPT, Claude, Gemini or a local chat UI | Zero effort; keeps the conversation | Not searchable across clients, no stable titles, revisions overwrite, references detached |
| Browser-extension prompt tools | Extensions that inject saved prompts into a chat web page | Fast injection into one site | Tied to the browser and to specific chat sites; text only; cloud-hosted by the extension vendor |
| Dedicated desktop library | 77Fox prompt library and similar desktop tools | Versions, references, search, offline use, local-first data | One more app to install; needs a sync story for multiple devices |
Criteria that separate a real prompt manager from a text box
1. Version chain per prompt, not per page
A prompt is refined dozens of times. The manager should keep named versions side by side so draft seven can be compared with draft twelve, and it should snapshot automatically before every change so a bad edit or an accidental deletion is reversible. In 77Fox, each prompt carries as many versions as you need, each with its own name, text and references, and a copy is stored before every create, edit or delete and can be restored from "Restore an earlier version".
2. Reference media attached to the version
For image and video generation, the style image is part of the prompt. Look for attachments per version, drag-and-drop and paste from the clipboard, and previews large enough to judge detail. 77Fox allows up to 15 attachments per version across images (PNG, JPG, WebP, GIF, SVG), video (MP4, MOV, WebM, MKV and more), audio (MP3, WAV, FLAC) and PDF or PPT, with hover previews up to 4000×4000 on desktop.
3. Full-text search including old versions
Past a hundred prompts, browsing stops working. Search should cover titles, bodies and every version, and highlight the match. 77Fox does that and offers two sort orders: most recently changed, which floats your working set to the top, or manual drag order.
4. Where the data lives
Ask who can read your prompts. Extension and cloud tools usually hold them on the vendor's servers. 77Fox is local-first: prompts, finance and task data stay on your machine, and with sync enabled they are encrypted with AES-256-GCM before upload into your own Google Drive. 77Fox servers hold only account, device, entitlement and short-lived verification data.
5. Multi-device without silent overwrites
If you work on a desktop and a laptop, check what happens when both edit the same prompt. 77Fox merges categories, prompts and versions record by record and keeps conflicts as records instead of picking a winner. It also refuses to overwrite your library when the cloud data belongs to a different account.
6. Translation as a first-class version
Prompts often need an English and a Chinese pass, sometimes Japanese or Korean. 77Fox adds the translation as a new version named after the language, leaving the original untouched, with targets in Simplified Chinese, English, Japanese, Korean, French, German, Spanish, Portuguese and Russian. You choose the route: a free default channel, cloud translation included in a paid plan, your own API key, or an offline model on your machine.
7. Integration with the AI tools you already use
A library that only lives in its own window becomes a museum. 77Fox exposes the library through a local MCP server, so Claude Code, Claude Desktop, Codex CLI, Cursor, Gemini CLI, VS Code, Cline, OpenCode and Windsurf can search, read and create prompts with per-client permissions, and the built-in AI assistant can create prompts and categories for you, each write staged for confirmation first.
8. Cost and lock-in
Check what is free and whether you can get your data out. The 77Fox prompt library is free with no paywall on categories, versions, references or sync, and the desktop app can export the whole local profile as one backup file and import it on a new machine.
How the approaches score
| Criterion | Notes app | Chat history | Browser-extension tool | 77Fox library |
|---|---|---|---|---|
| Per-prompt versions | No | No | Rarely | Yes, plus automatic snapshots |
| References per version | Embedded in pages, not per version | Per conversation | Usually text only | Up to 15 per version |
| Full-text search across versions | Page-level | Single client | Within the extension | Yes, with highlights |
| Local-first data | Depends on app | No | No | Yes |
| Encrypted sync to your own storage | Depends on app | No | No | Yes, own Google Drive |
| Offline use | Often | No | No | Yes |
| Translated versions | Manual | Ask again | Rarely | One click, nine target languages |
| MCP or assistant access | Rarely | Not applicable | No | Yes |
| Price | Free to paid | Included in AI subscription | Free to paid | Free |
Where 77Fox is not the right choice
Honest limits matter more than a long feature list.
- You need a team wiki. Long documents, meeting notes and relational databases belong in Notion or similar. The 77Fox library replaces only the prompt-warehouse slice of those tools.
- You work on macOS or Linux. 77Fox desktop is Windows 10/11, 64-bit. The web console covers categories, editing, versions, search and sorting and accepts dragged and pasted references with a 64 MB per-file limit, but one-click translation, snapshot restore, saving references out and full backup export need the desktop app.
- You only ever paste prompts into one chat site and never keep images. A lightweight extension may be enough, as long as you are comfortable with the vendor holding the text.
A 15-minute evaluation you can run on any candidate
- Save one prompt with a title, a category and a reference image.
- Edit it three times and try to get the first version back.
- Delete it and try to recover it.
- Search for a phrase that only appears in the second version.
- Open the tool on a second device, or turn the network off, and check what still works.
- Read the privacy page and find the sentence that says where the prompt text is stored.
A tool that passes all six is a prompt manager. A tool that passes the first is a text box with a title.
FAQ
Is 77Fox a free prompt manager?
Yes. Core Windows desktop features including the prompt library, versions, references and encrypted sync are free. Optional cloud AI plans start at £1.49 per month and are only needed for 77Fox cloud AI features.
Does 77Fox upload my prompts?
Not to its own servers. Prompts stay on your machine; with sync enabled they are encrypted with AES-256-GCM before being written into your own Google Drive, and the data key is managed through your Google authorisation.
Can I use the library from Claude, Cursor or Codex?
Yes. The desktop app hosts a local MCP server with connection configurations for Claude Code, Claude Desktop, Codex CLI, Cursor, Gemini CLI, VS Code, Cline, OpenCode and Windsurf. Each client gets read-only, write-without-deletion or full-trust access, which you can pause or revoke.
What happens on first launch?
Four categories and eight example prompts appear in your interface language, covering character setup, camera settings, visual style and video generation. Examples you never touched step aside automatically when you sign in to your own account.
Does the web app have the same library?
Desktop and web use the same library and sync through your own Google Drive. The web currently lacks one-click translation, snapshot restore, saving references out, custom reference folders and full backup export and import.
