Does the job

Pretty happy overall. On-the-go research workflow just works and combines browsing and AI in one app. Limited to its own browser environment can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Solid for our team

We rolled this out across the team last quarter and quick page summaries save reading time. On-the-go research workflow fits neatly into how we already work, and standard web browsing capabilities removed a step we used to do by hand. Quality depends on underlying model, which is the main caveat, but it has held up under daily use.

I've evaluated a lot of these over the years. What stands out here is integrated AI chat assistant — handled better than most — and built-in chat for instant answers. Worth the time if this is your use case.
