Nobody shares their growth alpha anymore. But most of it is public if you know where to look: ad libraries show which ads have been running for months (the winners), pixels show which platforms they buy, sitemaps show programmatic SEO, Wayback shows every repositioning, and founders post their playbook in public.
REM collects all of it from one link and turns it into a report: what the company's growth engine is, how the channels connect, and a step-by-step playbook to copy it. Every fact cites the evidence it came from, and everything REM couldn't see is listed as unknown, with a link to check it yourself.
Inspired by REA (Reverse Engineer Anything), but for marketing instead of binaries.

## Quick start
Try it with zero setup, no keys: a recorded Cal AI teardown opens in the web app.
 [code] 
Then run it on any company:
 [code] 
That works with **no API keys**: website, tracking pixels (including pixels hidden inside Google Tag Manager containers), SEO/sitemaps, AI-crawler stance, Wayback positioning history, App Store/Google Play and Hacker News.
Add keys to unlock the rest:
 [code] 
Output goes to `./rem-reports/ - /`: `report.md` plus `evidence.json` (the raw evidence bundle).
It also accepts App Store and Google Play links: `rem https://apps.apple.com/us/app/…/id123`.
 [code] 
## Web app: use your Claude Code or Codex plan
 [code] 
Opens a local web app at `http://localhost:4321`. Paste a link, pick who writes the report, and watch the evidence come in and the playbook stream out. Every `E12` citation opens the raw evidence behind it.
The **Posts & ads** tab is a review library of everything collected: Meta ads (active *and* paused, with creatives, inline video, run length, variants, top-by-impressions), Google and LinkedIn ads, TikTok and Instagram videos, YouTube, X and LinkedIn posts (company and founders), and Reddit threads and brand/founder replies. Filter by platform, sort by top / newest / longest running, open any original. The rail shows the brand logo and the founders with photos, roles, LinkedIn/X audience and a confidence badge.
