Show HN: Selector Forge – browser extension for AI-generated resilient selectors

A new browser add-on called Selector Forge dropped into Show HN with a very specific promise: click something on a webpage, and it gives you a selector — basically a way for software to find that thing again later. The twist is the tool uses AI to suggest options, but then double-checks every answer against the real page before showing it. Supporters instantly treated that last part like the plot twist that saves the movie: "the browser is the source of truth" became the reassuring line for people who are tired of flaky test tools making stuff up.

But the comments quickly turned into a familiar internet cage match. Fans called it a clever time-saver for testers, scrapers, and anyone automating repetitive web tasks. Critics fired back with the classic hot take: if websites were built properly, you wouldn't need a fancy AI helper to begin with. That sparked the usual blame game — bad front-end practices, fragile websites, lazy developers, and whether AI is solving a real problem or just putting a shiny sticker on an old headache. In other words: peak Hacker News energy.

The jokes were exactly what you'd expect. Some commenters basically translated the product into: "AI generates selectors, then another system checks whether the AI hallucinated", which they found either brilliant or hilariously on-brand for 2026. Others compared it to hiring an overconfident intern and then making the browser act as the strict manager. Even people who liked it couldn't resist teasing the setup. The vibe was a mix of impressed, suspicious, and deeply amused — which, honestly, is the internet's love language.
