Convai

Freemium

Convai is a platform for building AI characters that live in games, virtual worlds, and XR spaces. You create 3D avatars that can hear, see, talk, and remember what players said.

You set up characters through a browser interface or local tools. You feed them documents for backstory, pick voices and languages, and connect them to Unreal, Unity, or web engines.

It is built for Avatars & Characters work. Not for chatbots on flat websites. Not for quick voice apps without a visual presence.

Open it if you are shipping 3D characters that need to feel alive. Skip it if you just need a text chatbot or a simple voice bot.

It changes what you can ship when this is your job.

• Game studios building voice-interactive NPCs: Your characters respond to spoken words in real time. Players stop reading dialogue boxes.
• XR/VR experiences requiring spatial characters: Avatars turn toward sound sources and track where players move. The space feels real.
• Game developers building narrative-rich experiences with NPCs: Characters remember conversations from ten minutes ago. Stories carry weight.
• XR training simulation creators: Trainees talk to virtual instructors that respond with context. Scenarios adapt to what they say.
• Creators using NVIDIA Omniverse for 3D character workflows: You test characters with microphone input tied to Audio2Face animation loops.
• Metaverse and social virtual world developers: NPC-to-NPC dialogue lets characters talk to each other while players watch.
• Brands building 24/7 AI brand ambassadors in 3D spaces: Virtual reps stay on-brand and scale to many visitors at once.
• Enterprise teams requiring on-prem deployment and security compliance: ISO 27001 alignment and self-hosted options cover your security needs.

These are the parts you notice after building with it.

• Sub-second voice latency: Conversations flow like talking to a person. You do not watch loading spinners.
• Long-term memory of past conversations: Characters recall what you said earlier. The world feels persistent.
• Production-ready lip sync and facial animation: Your team skips weeks of integration work. The result looks finished.
• Mature Unity, Unreal Engine, and PlayCanvas integrations: You slot it into your existing pipeline. No engine swap needed.
• 65+ languages and 500+ voice options: One build ships globally. You pick the voice that fits the character.
• Free developer tier for prototyping: You test the full stack before spending. The risk stays low at the start.

You build in stages.

1. Upload documents for your character's knowledge base and backstory.
2. Pick a voice, language, and personality traits in the browser UI.
3. Install the SDK for your engine and connect the character to your scene.
4. Set up behavior trees and action triggers so the character can do things.
5. Test with microphone input, then ship to web, mobile, VR, or AR.

Skip it when these limits block your path.

• Character setup takes real time: Lore, behavior trees, and action triggers are not prompt-and-play. You need hours to make it work.
• Pricing jumps fast under load: Free works for one user. Small alpha tests hit $99/month. Real production runs $499 to $1,199.
• API credits burn quickly with concurrent players: Many users talking at once drains your budget fast. You need to meter carefully.
• Voice bot and IVR use cases are cramped: The tool wants a 3D avatar. Flat voice-only apps feel like a poor fit.
• Enterprise sales contact required for on-prem: You cannot self-serve the secure deployment. You wait for a rep.
