Use it every day

Honestly didn't expect to like it this much. Document & image understanding is exactly what I needed, and large ecosystem of plugins. but I reach for it almost every day now and it just clicks.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on voice mode, and strong reasoning caught me off guard. Usage limits on free tier is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Pretty happy overall. Data analysis just works and versatile across tasks. but no dealbreakers — I'd recommend it to a friend without hesitating.
