What is PostSnag?

PostSnag is a Chrome extension and dashboard that captures the public posts on any Facebook profile, Page, or group as you scroll, including the real video file behind every reel, then organizes them into a dashboard you can search, sort, compare, and export. Instead of scrolling Facebook and guessing what content is working, you get the real numbers behind every post in one place.

You browse Facebook exactly as you normally would, signed into your own account. As you scroll a profile, PostSnag reads the public posts already loading on your screen and collects the details that matter: the post type, how many reactions, comments, and shares it got, when it was posted, the caption, and the media. One click sends everything to your dashboard, where you can rank a profile's posts by engagement, spot the outliers, compare profiles side by side, save the best ones, and export the whole set for deeper analysis.

The two parts of PostSnag

The Chrome extension is the capture engine. It adds a PostSnag panel to Facebook that appears when you open a profile, Page, or group. As you scroll, the panel shows a live count of what it has collected, a quick breakdown of engagement and post types, and an Export To Dashboard button. For a video or reel, PostSnag saves the real playable video file itself, plus a cover image, not just a thumbnail. Nothing is sent anywhere until you click Export To Dashboard; capturing while you scroll only builds the data up locally in your browser.

The dashboard is where your captured posts live, organized along a sidebar:

• Overview: your home screen, a snapshot of everything you've captured.

• Profiles: every profile, Page, or creator you've captured, each opening to its own Posts, Reels, and Analytics tabs.

• Posts: every post you've captured, from every creator and every group, in one place.

• Groups: every Facebook Group you track, each with its own Posts, Profiles, and Analytics tabs.

• Compare: line up to three profiles side by side.

• MCP: connect Claude, ChatGPT, Grok, or Perplexity so it can read your captured library and answer questions about it in the chat. PostSnag MCP is included with Pro and Lifetime.

• Discovery: the caption and hook patterns working across the creators you track.

• Bookmarks and Folders: save and organize what you find.

• Recent scans: a shortcut back to what you scanned lately.

What PostSnag captures from every post

For each public post you scroll past, PostSnag collects:

• Post type: text, photo, video, reel, album, or link

• Reactions, including the breakdown of like, love, haha, wow, sad, and angry, visible in the dashboard

• Comments and shares

• Video views, when a post is a video or reel

• The exact date and time it was posted

• The caption text

• The media, including the real video file and a cover image for videos and reels, not just a thumbnail, plus up to 20 images from an album

• The author's public name and profile link, and the original post URL

PostSnag only ever reads public posts, the same ones anyone visiting that profile could see. It never captures private or friends-only posts, Messenger or direct messages, Stories, or live video.

What makes PostSnag different

• It works on profiles you don't own. Facebook only gives analytics for Pages and profiles you manage. PostSnag lets you see post-level performance for any public profile, Page, or group.

• It runs in your own browser, read-only. PostSnag uses your own logged-in Facebook session and only reads what's already on your screen. There are no proxies, no fake accounts, and no automation, and it never posts, likes, comments, messages, or follows anyone for you.

• It covers profiles, Pages, and entire Facebook Groups. Scroll a group's own feed for every member who posts, or a single member's profile for just their posts.

• It focuses on organic content. These are the real posts creators publish, not just paid ads.

• Its exports are built for AI. The Export menu has three options: Download data for AI (a Markdown file and a CSV file together), Download media for AI (a .zip of the images and videos), and Download Data & Media for AI (a .zip with both). Paste the Markdown or CSV into ChatGPT, Claude, or Gemini, or hand an AI that accepts uploads the real video and image files so it can watch, not just read.

• It connects directly to your AI, on Pro and Lifetime. PostSnag MCP is included with Pro and Lifetime and lets Claude, ChatGPT, Grok, or Perplexity read your captured library directly, so you can just ask instead of exporting a file first.

• It finds the patterns for you. Discovery studies the creators you personally track and names the caption and hook patterns actually pulling reactions, so you're not just staring at a spreadsheet.

Who PostSnag is for

• Marketers, agencies, and brand strategists auditing competitor or client profiles. Capture a profile, sort by engagement, and hand over a clear picture in minutes instead of scrolling months of posts by hand.

• Content creators who want to stop guessing. Study what's working in your niche across several profiles and build a swipe file of proven posts.

• AI-forward users who want clean, structured Facebook data, real captions and real media, to feed into AI tools for content strategy and competitive research, or to ask directly through PostSnag MCP.

• Facebook Group admins and community managers looking at what content resonates inside a community and who the top contributors are.

What PostSnag does not do

PostSnag is a research tool, not an automation tool. It does not manage your Facebook account, post or schedule content, message people, or interact with profiles in any way. It is also not affiliated with Facebook, and it never asks for your Facebook password. You stay logged into your own Facebook account normally while PostSnag reads the public posts on your screen.

Common questions

Is PostSnag free?

Yes, there's a Free plan at $0 with no card required. On the Free plan you get 3 profile scans and 2 group scans in any rolling 7-day window, and each scan previews the first 30 posts in your dashboard. Pro and Lifetime remove the Free plan's caps entirely and add Discovery and PostSnag MCP. See What do PostSnag's plans include, and what are the limits?.

Do I need a Facebook account?

Yes. PostSnag reads posts through your own logged-in Facebook session, so you need to be signed into Facebook as usual. Your PostSnag account is separate and never touches your Facebook password.

Is this the same as CrowdTangle?

It solves a similar problem now that CrowdTangle is gone. See Is PostSnag a CrowdTangle alternative?.
