What is Mesurer?
Mesurer is a Chrome extension that lets you inspect, annotate and direct changes on your live interface so your coding agent builds precisely what you mean. It installs from the Chrome Web Store, and a setup prompt helps connect it to your agent.

- Free Chrome extension with a large install base
- Pairs with your coding agent
Cons: where it falls short
- Chrome only
- Pricing is not stated on the site
