How to Use Convai in 2026: Step-by-Step Guide
Convai provides conversational AI infrastructure for building intelligent NPCs in games, virtual reality, and metaverse applications. Characters built on Convai can have open-ended conversations, remember players, navigate knowledge bases, and take in-game actions — all in real time.
Convai is one of the leading platforms for adding conversational AI to interactive experiences — games, VR training simulations, virtual events, and metaverse environments. It's used by developers who want NPCs that can have real conversations, not just follow dialogue trees.
Conversational Character API
Convai's core product is a character API: define a character's backstory, personality, and knowledge, then call the API with player speech or text. The API returns a text response and, optionally, audio (via built-in TTS). Characters maintain conversation history, stay in role, and handle edge cases gracefully.
Knowledge Grounding
Characters can be grounded in custom knowledge bases — game lore documents, quest information, NPC backstories. When a player asks about the history of the kingdom, the NPC answers accurately from the lore document, not just from the AI's general training. This prevents hallucination and ensures narrative consistency.
Actions Framework
Beyond dialogue, Convai's Actions framework lets NPCs trigger in-game behaviors. When an NPC decides to give the player an item, open a door, or call for backup, these intentions can be mapped to game engine events. This bridges conversation and gameplay.
Multiplayer and Persistent Memory
Convai supports persistent memory: NPCs remember what players told them in previous sessions. A player who helped the blacksmith in Chapter 1 will be remembered when they return in Chapter 3. This creates the sense of a living world.
Integrations
Convai provides Unity and Unreal Engine plugins, a REST API, a Python SDK, and integrations with NVIDIA ACE (for avatar animation). Developers can deploy characters in games, VR experiences, WebGL environments, and video.
Pricing
Free: 100 interactions/day. Pro: $20/month (5,000 interactions). Enterprise: custom. Students and researchers get extended free access.

Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Convai supports npc-conversations, knowledge-grounding, persistent-memory, in-game-actions, voice-ai, character-creation — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Convai what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
