New to PostSnag? Capture your first Facebook profile and see what content is working in under two minutes.

Getting Started

PostSnag is a Chrome extension and dashboard that captures the public posts on any Facebook profile, Page, or group as you scroll, then lets your AI read that library on Pro and Lifetime.

What is PostSnag?

PostSnag is Facebook-only today; it does not capture posts from Instagram, TikTok, LinkedIn, or any other platform yet.

Does PostSnag work on Instagram, TikTok, or other platforms?

Plain-language definitions for every PostSnag term, from Capture and Scan to Overview, Posts, Compare, MCP, Discovery, and the three export options.

What do the key PostSnag terms mean? (Glossary)

PostSnag captures posts client-side from your own session, covers profiles, Pages, and Groups, and lets Claude, ChatGPT, Grok, or Perplexity read your library directly.

How is PostSnag different from other Facebook research tools?

PostSnag captures posts, including the real video file behind every reel, as you scroll your own Facebook session, then syncs them to your dashboard when you click Export To Dashboard.

How does PostSnag work?

PostSnag is read-only and client-side: it uses your own Facebook session and never acts on your behalf.

Is PostSnag safe to use?

PostSnag has three plans: Free, Pro, and Lifetime. Free is capped at 3 profile scans and 2 group scans in a rolling 7-day window, each with a 30-post preview; Pro and Lifetime remove every cap.

What do PostSnag's plans include, and what are the limits?

CrowdTangle is gone and Facebook offers no native analytics for accounts you don't own; PostSnag fills that gap differently, with a genuinely free tier and a direct AI connection on Pro and Lifetime.

Is PostSnag a CrowdTangle alternative?

A step-by-step first capture: install PostSnag, sign in, open a Facebook profile, scroll, then export to your dashboard. Free covers your first capture, no card required.

How do I capture my first Facebook profile? (Quick start)

PostSnag captures public posts, including the real video file behind every reel, on profiles, Pages, and groups; never private posts, Messenger, Stories, live video, or Facebook's own Reels tab.

What can and can't PostSnag capture?

PostSnag walks new accounts through a guided tour, a getting-started checklist, and a short welcome video on day one, with breadcrumbs to keep you oriented.

How do I get started on my first day?

PostSnag is building an MCP that connects it to AI tools, pinned-post detection, multi-language support, a weekly digest, engagement rate everywhere, and expansion beyond Facebook.

What is PostSnag building next?

Quick fixes for capture counts, missing posts, sign-in, and anything that looks off.

Troubleshooting

The toolbar popup and the on-page panel are two separate windows sharing one PostSnag sign-in, and they usually sync within a moment of each other.

Why am I asked to sign in twice?

Scrolling back over posts you've already passed can make the Collected count pause briefly. PostSnag won't count the same post twice.

Why does the Collected count change when I scroll back up?

A connection error after exporting usually means your network is blocking app.postsnag.com or api.postsnag.com, not that your capture failed. Your data stays saved either way.

Why do I get a connection error when I export?

Message the team through the support popup in the bottom-right of any dashboard page, or email support@postsnag.com. You'll usually get a reply within one business day.

How do I contact PostSnag support?

The panel usually catches up within a few seconds of switching profiles. The dashboard only updates when you export again, and the panel's refresh button starts a fresh scan, not a quick sync.

Why does my dashboard data look out of date after switching profiles?

No. PostSnag reads posts that are already loading on the page as you scroll, instead of running separate background processes of its own.

Does PostSnag slow down Facebook or my browser?

A post published moments before you scan can still be settling into Facebook's feed, so it may not appear until you capture and export it again.

Why does my export seem to be missing the most recent post?

The earliest post on a profile can be missed on a first pass since it may load before PostSnag finishes starting up on that page. Here's why, and how to catch it.

Why does the first post on a profile seem to be missing?

PostSnag now captures the real video file behind every reel and video, plus a cover image, but any media can still be missed if it hadn't finished loading when PostSnag read the post.

Why didn't a photo, album, or video fully capture?

Yes. PostSnag captures posts by their structure, post type, media, and engagement numbers, not by the language they're written in.

Does PostSnag work on non-English Facebook?

PostSnag can only capture posts that have actually loaded on your screen, so an unloaded page, a signed-out tab, or an unsupported section can show zero posts collected.

Why is nothing getting captured on a profile?

PostSnag's Free plan previews 30 posts per profile scanned within your weekly allowance; a profile scanned beyond it is saved but fully locked. Upgrading unlocks everything at once.

Why am I only seeing a preview of a profile's posts? (Free plan)

PostSnag counts what it actually captures from your screen as you scroll, so panel, dashboard, and Facebook totals can differ slightly. That's expected.

Why do post counts look different across the panel, dashboard, and Facebook?

Shared posts, tagged posts, and Group context can attribute a captured post to a profile you did not expect. Here is why, and how to fix it.

Why do posts show up under a different profile than expected?

PostSnag reads a profile's name and picture from the page as it captures, so a loading page or a recent photo change can briefly show the wrong one.

Why does a profile's name or picture look wrong?

PostSnag renews your sign-in automatically in the background. When that fails, it signs you out cleanly instead of leaving your session half-working.

Why was I signed out unexpectedly?

Your plan is checked fresh every time a page loads, so a short delay right after upgrading, before an already-open tab catches up, is expected.

I upgraded but still see free-plan limits. What do I do?

Download your captured posts for any AI, or connect PostSnag MCP and ask Claude, ChatGPT, Grok or Perplexity directly.
