Browser extension that reads the YouTube caption track and paints a per-segment sponsor probability on the seek bar before the intro ends, with no crowd database; reports catching 77% of SponsorBlock's sponsor seconds across 23 videos at $0.0008 a video.

Chrome extension (Manifest V3) that covers a YouTube comment while one Jev Noul question decides whether it reveals a concrete plot event, fate, ending or result of the video being watched or of any other title the user chose to protect; the typed question lives in the extension, application code owns the 0.5 / 0.7 / 0.85 threshold, and a failed or quota-rejected check leaves the comment covered rather than revealed. Requests go through the author's Cloudflare Worker, which forwards comment text, video title and channel but not the anonymous install ID; the committed evaluation is a 10-sample hand-written regression set across English, Chinese, Japanese and prompt injection, not a production accuracy measurement. Install PlotVeil.
Chrome/Firefox extension that uses Jev through TypeSafe or Vercel AI Gateway to classify bounded page-element snippets, then stores reusable local hiding rules by page template. Paid analysis is manual by default; optional on-visit analysis sends snippets to the selected provider. The API key stays in unencrypted local extension storage.
Local voice-controlled Playwright browser: Jev chooses a typed intent and target from speech and a bounded page snapshot, while code applies confidence gates and asks for confirmation before actions it classifies as destructive. The Web Speech API sends audio to Google, and transcripts, page context, and recent actions go to TypeSafe; the author's 34-case integration result uses captured fixtures, not arbitrary websites.
