Our take: Triall suits researchers, analysts and anyone who wants hard questions checked by three frontier models that answer blind and critique each other, with 3 free sessions on the homepage and credit packs from $7 without a subscription.
Main limitation: The free tier allows very few sessions with 2 iterations, usage is metered in monthly credits, and API access is listed as coming soon.
