Always Free to Use
Start chatting without a paid plan. PubCog is designed around free access first, so useful AI remains available before you connect any accounts.
Best Available Model
Every request is routed to the strongest available model for the job. PubCog weighs quality, reliability, and availability, then falls back when a model is slow or unavailable.
Add Free Providers
Connect your own free-tier provider accounts to expand your personal router. PubCog can use those keys securely for more capacity, better stability, and more model options.
