Real-time AI avatars used to be something only large companies could afford. Prices have come down, but costs still vary widely between providers, and the headline monthly plan rarely tells the whole story. This guide explains what drives the cost of a speaking AI avatar, how to compare services fairly, and what Captivation AI costs.
What makes real-time avatars expensive?
A speaking avatar has several moving parts, and each one can add cost for every minute of conversation:
- Rendering the avatar. Many real-time avatar services generate video continuously on a server and stream it to the user. That needs significant compute and bandwidth for every minute of every conversation.
- Voice. Turning AI text into speech with a text-to-speech service is one of the more compute-intensive and expensive parts of a speaking avatar.
- The AI itself. The large language model that writes the answers has its own cost, which some providers include and others do not.
- Bandwidth. Streaming video to every visitor adds data costs that grow with usage.
How to compare AI avatar pricing fairly
When you compare providers, put them on the same basis:
- Convert everything to cost per minute or per hour of real conversation, at the volume you expect.
- Check what is included. Does the price cover the avatar, the voice, the speech recognition and the LLM, or only some of them?
- Check how usage is measured. Some services charge per minute, others per conversation or per character.
- Look for setup and minimum fees, and whether you can cancel monthly.
- Test response speed and expressiveness, not just price. A cheap avatar that feels slow or stiff will not keep customers engaged.
Why browser-rendered avatars cost less
Captivation AI takes a different approach to most real-time avatar platforms. Instead of generating and streaming video from a server, Captivation delivers pre-created visual assets to the browser and brings them to life with lightweight real-time instructions. The avatar is rendered on the user's own device.
This dramatically reduces server-side video generation, compute and bandwidth, which is why Captivation's costs can be up to 90% lower than conventional real-time video avatar services.
Captivation also reduces voice costs. Its Voice Optimisation technology matches around 80% of response phrases to audio already generated for a particular voice and reuses the stored file instead of making a new text-to-speech request. That can reduce typical voice-generation costs by up to 80%, without changing the quality of the voice.
What does Captivation AI cost?
Captivation Inside (for adding an avatar to your existing chatbot or AI agent):
- Usage-based pricing. Avatar use costs less than one cent per minute of normal conversation, based on approximately 750 characters per minute.
- A typical total cost for an avatar with voice is around 1 to 2 cents per minute, roughly $0.60 to $1.20 per hour.
- Plans from $100 (£75) a month. Your own LLM costs are separate, because you keep your existing AI.
- A free developer trial with credits for about 30 to 40 minutes of conversation, subject to availability.
Shopify SuperAgents (a complete AI shopping assistant with avatar, voice, knowledge and actions):
- Plans from $65 (£49) a month, with usage pricing from around 10p per customer conversation.
- A conversation covers communication between the customer and the SuperAgent during the two hours after the first interaction, up to 15,000 avatar characters.
- A free trial with credits for 50 customer conversations.
There is no setup fee for many standard packages, including basic Captivation Inside and SuperAgents for Shopify with self-setup instructions. Rolling monthly contracts can be cancelled at the end of the current monthly period. Volume, Enterprise and partner pricing is available for larger deployments.
The trade-off to know about
Captivation's current avatars prioritise expressive communication, gestures, speed and affordability rather than maximum photorealism. Some other services offer more human realism, usually at a higher cost and with fewer expressive options. If your priority is an affordable, responsive avatar that can run at scale, browser rendering is a strong fit.
