A Chrome MV3 extension that sends your lead magnet by DM to people who comment on your tweet: a keyword match decides first, and Jev via OpenRouter classifies ambiguous comments, with your click required in the 0.4 to 0.8 band.

Highlights
- Above 0.8 the lead is processed; between 0.4 and 0.8 it waits in 'À valider' for your click; below 0.4 it is ignored.
- Without an OpenRouter key only comments containing the keyword are processed, per the README.
- It re-checks the XChat conversation so nobody gets the same link twice; closed DMs are retried in later cycles.
- Human-scale limits: 20 DMs/day (60 with X Premium), quiet hours 21h-8h, typed word by word, varied message forms.
- Pre-release and not on the Chrome Web Store; build it with Node 24 and pnpm 11. The README and UI are in French.
Quickstart

cd cash-boost-chrome
pnpm install
pnpm buildWatch out
README reviewed 2026-10-17; the digest truncates inside the usage warning, and the Jev classification details here come from the same French README's feature section. The extension is pre-release, relies on X's internal APIs, and the README warns that automating X violates its terms of use.
Questions about this entry
Short answers drawn from the linked project or page.
A Chrome MV3 extension that turns comments on your tweet into DMs: it detects who asked for your lead magnet, checks XChat so nobody gets the link twice, and sends the DM from your own X session at human pace.
A keyword match decides first. For comments without the keyword, the Jev model via OpenRouter returns a probability: above 0.8 the lead is processed, between 0.4 and 0.8 it waits for your click in 'À valider', and below 0.4 it is ignored. Without a key only keyword comments are processed.
The README and UI are French; the project is a pre-release ('pré-version') by mathieuhq. The code is organized as a pnpm monorepo with the domain vocabulary documented in CONTEXT.md, and pull requests are welcome with tests.
The README lists 20 DMs per day (60 with X Premium), 100 replies, 30 likes per hour, quiet hours from 21:00 to 8:00 by default, reduced quotas in the first week, and short randomized delays. The values live in packages/application/src/config.ts.
It runs in your browser with your X session and stores campaigns, leads, and the OpenRouter key in chrome.storage.local — no server, no account. Comment text leaves the browser only to be classified by Jev, sent directly to OpenRouter with your key.
The README's warning: automating actions on X violates its terms of use and your account may be limited or suspended. The extension shows the warning on first launch and stops itself if X returns a restriction signal; you use it at your own risk.
It is not on the Chrome Web Store, so build it from source: Node.js 24 and pnpm 11, then clone, pnpm install, and pnpm build, then load apps/extension/build/chrome-mv3-prod as an unpacked extension in developer mode.
