Turn a game or web scene into a live NPC with voice, actions, and memory.

Convai Game Development NPC Real-Time Voice AI Freemium from USD 22.00/mo

Our Verdict

Convai is the better fit when the experience depends on NPC conversation inside a game, simulator, or browser world. It saves a lot of character plumbing. The catch is that quota limits, engine setup, and better voice features start mattering as soon as the demo attracts real traffic.

check_circle Pros

  • ✓Unity, Unreal, and web paths are already documented for real deployment.
  • ✓Dialogue, actions, knowledge, voice, and vision sit in one character stack.
  • ✓The FAQ and pricing pages expose hard limits before they surprise you later.

cancel Cons

  • ✕It is too much setup if you do not have a character-driven product.
  • ✕The free plan tops out at 100 interactions a month.
  • ✕Better concurrency, larger knowledge banks, and premium voice use get expensive fast.

Should you use it?

voiced NPCs, XR trainers, and browser characters that need live conversation inside the scene

Skip it if: you only need a text chatbot, not a character living inside a game or simulation

Is it worth the price?

Freemium Starts at USD 22.00

You can prove a character concept for free, but production math starts early here. More than one live session, more interactions, larger knowledge banks, or better voices push this out of demo territory fast.

The Free Tier

100 interactions a month.

Paid Upgrade
$22/month yearly

3,000 interactions, one live session, and a 5 MB knowledge bank.

One thing to know before you start

Test one narrow NPC inside the real scene loop first. Quota pain shows up sooner than dialogue polish issues.

What people actually use it for

Talkative NPC prototypes

This is the cleanest fit: one NPC needs to answer the player, stay in role, and react in real time without your team building the conversation stack first. It is a fast way to learn whether live dialogue actually improves the scene.

Browser character demos

Convai works well for browser worlds, pitch demos, and guided experiences where a visitor talks to a character instead of clicking through a static flow. The main pressure point is traffic: shared testing can burn through free limits quickly.

Training simulations

It also fits training scenes where a character needs rules, knowledge, and action boundaries instead of generic chat. That matters in XR practice runs and guided simulations. You still get building blocks, not a finished training product.

What does Convai actually do?

The easiest way to judge Convai is to ask whether your character needs to do more than answer text. If the answer is yes, its mix of speech, actions, vision, lip sync, and scene integration saves a lot of custom glue work. If the answer is no, a simpler chatbot stack is usually the cheaper path.

The paid plans are not just about message volume. They also change how many live sessions you can run, how large the knowledge bank can get, how much flagship-model usage you can burn, and whether better voice options stay available. That makes Convai easy to prototype with, but harder to ignore once usage grows.

What you can do with it

Create voiced NPCs that answer, act, and stay in character.
Ship through Unity, Unreal, PlayCanvas, and web SDK paths.
Attach documents and knowledge banks to ground character replies.
Add lip sync, animations, and vision to scene-based characters.
Use Character Crafting APIs for backstory, actions, memory, and evaluation.

Top Alternatives to Convai

If Convai is close but still misses the job, try one of these instead.

Character.AI
Character.AI fits better when the goal is public character chat and roleplay without building a scene first.
AI Dungeon
AI Dungeon fits better when the goal is branching story play, not a character inside a game or browser world.

Key Questions

Is Convai for normal website chatbots?
No. It is built around characters living inside games, browser scenes, simulations, and XR setups. If you only need a support chatbot on a site, this is heavier than you need.
Can Convai work with custom avatars?
Yes. Convai is avatar-agnostic, but lip sync is not automatic for every model. It works properly only when the avatar already has a supported blendshape setup such as OVR, ARKit, or Reallusion.
Does Convai offer a free plan?
Yes. The free tier is $0, but it is capped at 100 interactions a month. That is enough to test one character loop, not enough to run a busy public experience.
When do paid plans become necessary?
Usually once more than one live session matters or the free quota disappears into testing. The first paid tier starts at $22 a month on yearly billing and moves the product out of pure demo territory.
