PostSnag

What is PostSnag?

PostSnag is a Chrome extension that turns Facebook scrolling into competitive research. It captures posts as you browse — from any profile, group, or reel — ranks them by likes, comments, shares, and video plays, and surfaces the viral outliers in a live discovery feed. No proxies, no burner accounts, no screenshot folders you never open again.

Key features

• One-click capture while you scroll — build a swipe file of winners without copy-paste.
• Engagement ranking — sort everything you’ve captured by what actually performed.
• Outlier detection — the discovery feed flags posts massively over-performing their page’s baseline, which is where repeatable formats hide.
• AI export — pipe clean post data straight into Claude or ChatGPT to deconstruct why something worked and draft your own take.

Pricing

Free to try, ~$19/month for Pro — or a $139 lifetime deal that ends the subscription question.

Who it’s for

Creators and marketers on Facebook — which matters more than it did two years ago, now that Facebook’s creator payouts have made it a genuine monetization platform again. If FB is part of your distribution, this is the research layer it never had.

Verdict

A young tool with a sharp, specific job. If Facebook is in your mix, the lifetime deal is the sensible buy; if it isn’t, skip it — this one’s a specialist.
