Use it every day

Honestly didn't expect to like it this much. Centralized AI workspace is exactly what I needed, and access to many models in one place. I do wish quality depends on underlying third-party models, 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 side-by-side model exploration, and access to many models in one place caught me off guard. still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: side-by-side model exploration and useful for comparing model outputs. Where it lags: quality depends on underlying third-party models. On balance the feature set — especially multi-model chat interface — justifies the 5 stars for our use case.

I've evaluated a lot of these over the years. What stands out here is side-by-side model exploration — handled better than most — and access to many models in one place. Worth the time if this is your use case.
