Everything you need to know about GenCatalog. Can't find your answer? Email us.
GenCatalog is a desktop application and Chrome extension that automatically captures, catalogs, and organizes your AI-generated images and videos from Grok Imagine, Higgsfield, Midjourney, and Digen — all in one fast, searchable local library on your computer.
The core idea: every generation you create is saved with its prompt, platform, model, and metadata — not just the file. So six months from now you can find exactly what you made and recreate it.
GenCatalog currently supports three platforms:
More platforms are planned for future updates.
No. Everything stays on your computer. GenCatalog runs entirely locally — there is no cloud sync, no remote storage, and no account required. Your files and prompts never leave your machine.
The only external communication is periodic license key validation with our payment processor (Lemon Squeezy), which sends only your license key — never your media or prompts.
macOS is fully supported (both Apple Silicon M-series and Intel). macOS 10.15 (Catalina) or later is required.
Windows is fully supported. Download GenCatalog for Windows at gencatalog.app.
The Chrome extension works on any platform with any Chrome-based browser.
No. GenCatalog is an independent product by Second Act Labs. We are not affiliated with, endorsed by, or partnered with xAI (Grok), Higgsfield, or Digen. GenCatalog works with the publicly available interfaces of these platforms.
This means the GenCatalog desktop app isn't running. The extension needs the app to be open to save content.
If the app is open but still shows "Not Running," try quitting and relaunching GenCatalog.
You choose the folder on first launch. GenCatalog creates this structure inside it:
images/ — all saved imagesvideos/ — all saved videosthumbnails/ — auto-generated video thumbnailscatalog.json — your metadata database (prompts, tags, etc.)trash/ — deleted items (recoverable)You can move this folder to an external drive or NAS at any time — just relaunch GenCatalog and point it to the new location.
Yes — GenCatalog needs to be running for the Chrome extension to save content. However, it lives quietly in your menu bar (Mac) or system tray (Windows) and uses minimal resources when idle.
You can set GenCatalog to launch at login so it's always ready — on Mac: System Settings → General → Login Items. On Windows: Settings → Apps → Startup.
Video thumbnails require FFmpeg, a free media tool that GenCatalog uses to generate previews. Image thumbnails work immediately without it — this only affects videos.
On Mac: During setup, GenCatalog will offer to install FFmpeg automatically. The process takes about a minute and doesn't require any technical steps.
On Windows: During setup, you'll be directed to a download page with the files you need. Follow the on-screen instructions to install FFmpeg, then restart GenCatalog.
If you skipped this step and video thumbnails still aren't showing, quit and relaunch GenCatalog — the FFmpeg setup prompt will appear again.
When you're on grok.com or x.com/i/grok and viewing a generation, a blue GenCatalog save button (the grid icon) will appear on the image or video. Click it to save instantly.
The button changes to a spinner while saving, then a green checkmark when done. If the item was already saved, it shows orange.
Yes. You can save content from multiple Grok accounts into a single catalog. GenCatalog automatically detects and tags each saved item with the account it came from, so you can filter your catalog by account.
To switch accounts: log out of Grok, log into your other account, and use the extension as normal. Each item is tagged with its source account automatically.
Yes — this is one of GenCatalog's core features. When you save from Grok Imagine, the prompt is automatically extracted and stored with the file. You can search your entire catalog by prompt text at any time.
Prompt extraction works best on individual generation detail pages. If you bulk-downloaded from favorites, some items may have been captured without full metadata if the page hadn't fully loaded when the extension scanned.
To fix: open the generation on Grok Imagine and save it again. GenCatalog will merge the new metadata with the existing entry — it won't create a duplicate.
GenCatalog maintains an exclusion list — when you delete something from your catalog, it's added to this list so it's never re-downloaded during future scans.
If an item keeps reappearing, it likely wasn't deleted through GenCatalog (e.g., you deleted the file manually from Finder). To fix this, find the item in your catalog, delete it using the GenCatalog interface (not Finder), and it will be permanently excluded from future scans.
GenCatalog adds save buttons throughout Higgsfield automatically:
Click the blue grid icon on any of these to save. A spinner appears while saving, then a checkmark when complete.
GenCatalog captures the following from Higgsfield generations:
This can happen if the page API data hasn't been intercepted yet when you save. Higgsfield loads high-resolution URLs through an API call that happens shortly after the page loads.
To get full resolution: wait a few seconds after the page loads before clicking save, or navigate to the generation's detail page and save from there. Detail page saves always capture the full-resolution file.
When you're browsing midjourney.com, a Save button appears on each image. Click it to capture the image along with its full prompt, model version, and all parameters automatically.
Yes — this is one of the most useful Midjourney features in GenCatalog. Here's how:
Re-scanning will only pick up new items, so you can run it anytime to stay up to date.
GenCatalog saves everything from your Midjourney generation:
--v)--ar), chaos, seed, style, stylize weight--sref) and character references (--cref)Yes. GenCatalog captures the model version from your generation history, so V7, V8, and future versions are all supported automatically. The model version is stored with each saved item and visible in your catalog.
No. GenCatalog is an independent product by Second Act Labs. We are not affiliated with, endorsed by, or partnered with Midjourney. GenCatalog works with the publicly available Midjourney web interface.
When you're on digen.ai, a blue GenCatalog save button appears on each of your generations. Click it to save the image or video with its metadata.
For bulk saving: a floating panel appears on Digen pages — click Scan from the extension popup's Digen tab to count available items, then Download All to save them in bulk.
GenCatalog saves the media file along with available metadata including the prompt and generation source. Digen metadata capture is actively being improved in ongoing updates.
Open GenCatalog (or go to http://localhost:8080 in your browser) and use the search bar at the top. You can search by:
You can add custom tags to any item in your catalog. Open any item, click the tag field, and type your tag. Tags are searchable and filterable — click any tag to see all items with that tag.
Good uses for tags: style names ("cinematic", "portrait"), project names, character names, or any category that matters to your workflow.
Click any item to open it, then click the delete button. Items go to Trash first — they're not immediately deleted.
To permanently delete: open Trash in the sidebar → Empty Trash. To recover a deleted item: open Trash → Restore.
Click any item to open it, then click Hide. Hidden items disappear from your main grid but stay in your catalog — nothing is deleted.
To view or restore hidden items: click Hidden Items in the sidebar. From there you can unhide individual items or manage them as a group.
GenCatalog checks for duplicates using two methods:
To run a duplicate scan: click Remove Duplicates in the sidebar. GenCatalog will show how many duplicates were found and remove them, keeping the oldest version of each.
Yes — from any device on your home Wi-Fi network. GenCatalog displays a QR code in the sidebar. Scan it with your phone's camera to open your catalog instantly.
For access anywhere (not just home Wi-Fi), install Tailscale on both your Mac and phone. This creates a secure tunnel so you can reach your catalog from anywhere, as long as your Mac is on.
Yes. Click the checkbox icon (☑️) in the toolbar to enter multi-select mode. Then:
Press Escape or click the checkbox icon again to exit multi-select mode.
GenCatalog includes a free trial that starts on your first launch:
After the trial ends, you can still browse your existing library — but saving new items is paused until you activate a license. Your files and data are never deleted.
Yes, at any time. Go to GenCatalog → License in the menu bar (Mac) or system tray (Windows) and enter your license key. Activation takes effect immediately.
No. Your existing library — all files, prompts, tags, and notes — stays completely intact. The only thing that changes is that saving new items is paused until you activate a license.
No. GenCatalog is a one-time purchase at $39. No monthly fees, no subscription. Your license includes all updates to the current major version.
We offer a 14-day money-back guarantee if GenCatalog doesn't work as described. Email [email protected] with your order number. See our full Refund Policy for details.
Almost none. GenCatalog runs entirely on your local machine. Your media files, prompts, tags, and catalog data never leave your computer.
The only external communication is license key validation with Lemon Squeezy (our payment processor), which sends only your license key identifier — never your media, prompts, or personal data.
The Chrome Web Store version of the extension may report anonymous usage statistics (installs, active users) to Google, as is standard for all Chrome extensions that opt into Google Analytics.
Yes — browsing your catalog, searching, tagging, and organizing all work completely offline. The only things that require internet are: saving new content from Grok Imagine/Higgsfield/Midjourney/Digen (since those platforms require internet), and periodic license revalidation (approximately every 7 days, with a 30-day offline grace period).
