Yes. BlueAI runs the same frontier models the expensive subscriptions sell — GPT, Claude, Gemini, Grok and DeepSeek — and a routing layer picks the best model for each question. You pay less because the product is focused, not because the answers are weaker.
Pro includes 10,500 messages a month, 36 research sessions, flagship models, file and image workflows, priority routing and a 120-turn conversation memory. Yearly billing is $50 — two months free.
You can start from the home page right away. A free account keeps your encrypted history synced, and creating one does not require an email address.
