Productivity Chrome extensions live in the browser where you already spend most of your work day — which makes them better positioned to actually change your habits than yet another standalone app. The category covers tab managers that prevent you from drowning in 47 open tabs, focus tools that block distracting sites during deep work, note capturers that save what you're reading without context-switching to another app, and time trackers that show where your hours actually go.
The problem with most productivity extensions on the Chrome Web Store: they're built for a generic user, then bloat over time with features nobody asked for. The tab manager you wanted gets buried under workspace integrations, AI summaries, and a paid tier you'll never use. The one feature you actually need is one of forty.
PlugThis flips this. You describe the exact productivity tool you need — "block Twitter on weekdays before 5pm" or "save every page I read for more than 2 minutes to a markdown file" — and get a working extension that does that and only that. Yours, owned, no subscription, no creep.

The useful ones are the ones that match your specific workflow. Generic top-10 lists rarely solve your actual problem because your bottleneck isn't the bottleneck someone else has. The advantage of building your own is the extension fits your habits exactly — no learning curve, no unused features.
