Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on in-browser AI side panel, and combines research and automation in one place caught me off guard. Effectiveness depends on underlying AI model is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: reusable prompt library and lives in a side panel for non-disruptive use. Where it lags: automation features have a learning curve. On balance the feature set — especially page and article summarization — justifies the 4 stars for our use case.
