Comparing against
Why people look for a Sider AI alternative
- •Free plan is very limited (roughly 30 daily credits / ~10 queries), effectively a trial
- •Confusing multi-tier credit system where premium models and Deep Research burn far more credits, and even 'unlimited' plans carry branded credit caps
- •No folders, conversation organization, or search across past chats, making good responses hard to find later
