What is PrevTool? The Chrome extension for Gofile links

1. What is PrevTool?

PrevTool is a browser extension for Google Chrome (and all Chromium-based browsers like Microsoft Edge, Brave, Opera, and Vivaldi) that adds hover previews for Gofile.io links. Whenever you encounter a Gofile link on any webpage - whether it's on Reddit, Discord, a forum, a blog, or any other site - you can hover over it to see a tooltip showing the contents of the Gofile folder.

The preview tooltip displays the folder's file tree (file names, types, sizes), along with metadata such as the total file count, total size, and the link's availability status. From the same tooltip, you can download files directly without ever opening the Gofile page in a new tab.

PrevTool was created to solve a specific productivity problem: when you're browsing a page with many Gofile links, opening each one in a new tab to check what's inside is slow and tedious. PrevTool eliminates that friction by bringing the information to you on hover.

2. Core features (Free tier)

PrevTool's free tier requires no sign-in and no account. Install the extension from the Chrome Web Store and it works immediately. Here is what the free plan includes:

• Hover to preview any Gofile link: works on Reddit, Discord (web), forums, blogs, documentation pages, and any website where Gofile links appear.
• Folder tree display: see file names, sizes, and types inside the Gofile folder without leaving the current page.
• Download files from the preview: click a file in the tooltip to start downloading it directly.
• Download All on gofile.io: when you're on a Gofile page, use the Download All button to start downloading every file in the folder in one click.
• Dead link detection: instantly see if a Gofile link is no longer available, so you don't waste time clicking broken links.
• Password-protected link detection: the tooltip tells you when a link is password-protected before you open it.
• 10 free previews per day: enough for casual browsing.
• No sign-in required: install and use immediately.

3. Premium features (5.99/month or 49.99/year)

PrevTool Premium is designed for power users who work with Gofile links frequently. It costs 5.99 EUR per month or 49.99 EUR per year (annual plan saves ~30%). Premium includes everything in the free tier, plus:

• Unlimited previews (Fair Use): no daily cap on how many Gofile links you can preview.
• Faster preview loading: priority processing for quicker tooltip display.
• Download All from preview tooltip on any page: hover a Gofile link on any website and click Download All directly from the tooltip, without visiting gofile.io.
• Thumbnail previews in tooltips: see image and video thumbnails directly in the preview for quick visual identification.
• Link highlighting without hover: Gofile links on any page are automatically color-coded - green for available, orange for password-protected, red for dead - so you can scan a page at a glance.
• Bulk analysis: paste multiple Gofile links at once in the extension popup and get a summary of all their statuses and contents.

4. What PrevTool is NOT

It is important to be clear about what PrevTool does not do:

• Not a bypass tool: PrevTool does not circumvent passwords, quotas, speed limits, or any other Gofile restrictions. If a link is password-protected, you still need the password. If Gofile rate-limits you, PrevTool respects that.
• Not a file host: PrevTool does not store or serve any files. All downloads are served by Gofile's own infrastructure. PrevTool simply provides a more convenient way to trigger those downloads.
• Not affiliated with Gofile: PrevTool is an independent product. It is not made by, endorsed by, or affiliated with Gofile in any way.
• Does not modify Gofile: PrevTool does not inject scripts into Gofile's website or alter the Gofile interface. The tooltip is rendered in a Shadow DOM on the page you're browsing, completely isolated from the host page.

5. Who uses PrevTool?

PrevTool is useful for anyone who encounters Gofile links regularly. Typical users include:

• Forum and Discord browsers: people who visit pages (Reddit, Discord, forums, Telegram web) with many Gofile links and want to check what's inside each link without opening dozens of tabs.
• Moderators and community managers: people who need to quickly verify whether shared Gofile links are still valid, dead, or password-protected.
• Power users with bulk workflows: people who deal with large batches of Gofile links and need bulk analysis, Download All, and link highlighting to work efficiently.
• Anyone tired of tab overload: if you've ever opened 10+ Gofile tabs just to find the one file you need, PrevTool solves that by letting you preview before you click.

6. Technical details

For those who care about how the extension is built and what it does under the hood:

• Chrome Manifest V3: PrevTool uses the latest Chrome extension platform (Manifest V3), which is the current standard required by the Chrome Web Store.
• Lightweight, no performance impact: the extension only activates when you hover a Gofile link. It does not run background processes that slow down your browser.
• Shadow DOM tooltip isolation: the preview tooltip is rendered inside a Shadow DOM, which means it cannot conflict with the styles or scripts of the website you're browsing. No visual glitches, no broken layouts.
• Available on Chrome Web Store: install PrevTool directly from the official Chrome Web Store for Chrome and any Chromium-based browser.
