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.
Triall has a free Explorer plan with no card: 1 free session on the pricing page (the homepage says 3) and 2 reasoning iterations. Reasoner costs $11 per month for 150 credits, Architect costs $26 per month for 500 credits and Collective costs $66 per month for 1,500 credits. Yearly prices are $126, $312 and $792, saving 30% to 33%.
Monthly versus annual labeling is unclear, and the homepage structured data lists $15, $39 and $99 for the same plans. Credit packs are one-time: 50 credits for $7, 150 for $18 and 500 for $55. Prices checked on 2026-09-29.
