Tallgrass by MacRandle Acres
Works on every group, page and profile you can already see

Find the post that broke out.
Then write the next one.

Tallgrass scores every post against the median for its own group — so a quiet group's runaway hit stops being buried under a big group's ordinary day.

New rate sheet for August is up on the site

44 reactions 6 comments 1 shares vs 118 typical for this group

Sample data, drawn the way the real feed draws it — and look at the second row. It pulled more reactions than the one above it and still ranks lower, because its group does that on a normal day. Every most-engagement leaderboard puts those two in the wrong order.

Why the ranking is different

A big number and a breakout number are not the same thing

Sort by raw engagement and the biggest groups win every time — you end up reading a 40,000-member group's average Tuesday. Tallgrass measures how far each post beat the typical post in its own group, then ranks on that multiple. A 1,900-reaction post in a group that does that every week is noise. A 1,600-reaction post in a group that usually sees a hundred is a formula worth stealing.

Same feed, both groups. The one on the left is the post worth reading — and on a raw-engagement leaderboard it never appears.

Works everywhere on Facebook

Capture from any group, page or profile

Whether you're studying a niche group, a competitor's page or a creator who posts every day, Tallgrass collects their posts as you browse and puts them in one ranked feed.

Facebook Groups

The groups you're already a member of. Every post gets scored against that group's own baseline, so each group is judged on its own terms.

Pages and competitors

Follow brand pages and local businesses to see which offers, topics and formats their audience actually responds to.

Profiles and creators

Track people who post constantly and find their few real winners without scrolling months of timeline.

How it works

Read, rank, write

Three steps, and the third is the one that pays. Finding the outlier is only half the job — the other half is writing your own version of it.

Once you've found it

Turn a winner into your next post

Remix

Take a post that beat its group and get variants that reuse the mechanic that made it work — the same hook shape, your subject, new specifics. It reads the engagement mix too: a post that drew comments did something answerable, and a post that drew shares did something worth forwarding. Those are different levers and they get written differently.

Sage

Ask questions of everything you've captured. Which group is worth your time, what keeps working in it, what you posted last month that is worth doing again. It answers from your own data, not from generic advice about posting at 9am.

The honest boundary

It only ever reads what you can already see

Tallgrass is a browser extension. It reads the posts on the pages you visit while you visit them — the groups you joined, the pages you follow. It does not sign into anything on your behalf, and it cannot reach a group you are not a member of. That is the real limit of the tool, and it is also the reason you can run it on your own account without wondering what it is doing when you are not looking.
