Find anything you (or anybody else) has ever posted
Flux gets it. Semantic search finds the post by meaning, not exact wording. Works on your own history — or on any competitor profile you're tracking.
The pain
You’ve said it before. You just can’t find it.
LinkedIn’s native search barely works. Chronological scroll doesn’t scale past a few hundred posts. Every prolific poster runs into the same wall.
I want to update and re-run my best-performing post from 2023 but I can't find it.
A prospect mentioned X — I know I've covered that topic — I want to share the post, not retype my take.
I'm planning a content series and need to audit what I've already said.
How it searches
Three search modes, one box
Type a query. Flux picks the best mode — or pick your own.
Mode 2
Semantic
OpenAI embeddings
Finds posts about a concept even with zero shared words. “Posts about imposter syndrome” surfaces your post titled “I almost quit last year”.
Mode 3 · Default
Hybrid
Reciprocal rank fusion
Combines keyword and semantic results using RRF. You get the precision of exact matches plus the recall of meaning-based search — in a single ranked list.
Plus
Find similar posts
Click any post, get the 10 closest by meaning — powered by vector similarity over every post embedding. The moment you select a post, Flux walks your entire history for embedding neighbors. No queries, no tagging — just the shape of the idea.
Works on any loaded profile
…or anybody else
Explore runs against the profile currently loaded in Flux. If you track competitors, prospects, or thought leaders via streams, you can semantically search their content too.

Who it’s for
Built for people with post history worth revisiting
The prolific poster
Three-plus years of LinkedIn history. You know the gold is in there — you just can’t dig for it by hand anymore.
The coach
Building a best-of reel for a client who needs proof the method works — across a year of their own posts.
The consultant
Pulling past takes into a proposal. “Here’s everything I’ve published on this topic in the last two years” — in one minute, not one afternoon.
Tier availability
Explore is an Edge feature
No add-on pricing, no per-seat surcharge.
Edge
$15/ month
Semantic search requires OpenAI embeddings, which only the Edge tier’s pipeline generates for every post. Keyword-only search isn’t enough once your history gets real.
