ChatGate (formerly ChatGPT AI) vs Convai

ChatGate at chatgpt.ai is a third-party AI gateway that routes chat, image, and video requests across ChatGPT, Gemini, Claude, and other major models from one web interface. You pick a model manually or leave routing on Auto, then generate without juggling separate provider accounts.

Unlike signing up directly with OpenAI or Google, ChatGate sells consolidated access through tiered subscriptions and adds a Discover feed that ranks newly launched AI apps by category. The chatgpt.ai domain redirects to chatgate.ai, so the product brands as ChatGate even though the listing URL predates the rename.

Builders, marketers, and researchers who want one bill for multiple frontier models fit here, especially if they also browse the Discover leaderboard for fresh tools. It is not the official OpenAI ChatGPT product at chat.openai.com.

Convai lets you build 3D AI characters that talk, see, and act inside games, XR apps, and virtual worlds. You craft a character's personality, backstory, and knowledge in a browser studio, then deploy it through APIs and plugins for Unity and Unreal Engine. The same character can run on websites, mobile apps, VR headsets, and physical installations.

Most chatbot builders output text in a flat window. Convai focuses on embodied NPCs that need spatial awareness, lip sync, gesture animations, and real-time voice inside a 3D scene. That narrow engine-first approach trades a generic website widget for deep integrations with game engines, avatar systems, and multimodal perception.

Game developers, XR training teams, and brand marketers use Convai for role-playing NPCs, virtual brand reps, and training simulations. The free tier includes 100 interactions per month, and paid Indie Dev plans start at $22 per month on yearly billing with 3,000 monthly interactions.
