Anam.ai
This is an infrastructure product, not an avatar video maker: the whole pitch is latency low enough that the face answers while you are still expecting it to. Tool calling and knowledge-base retrieval mean it can actually do things rather than just talk. The cost model is per minute, which is fine for demos and brutal for anything always-on.
Pros
- Real-time interaction rather than rendered clips, with a published latency figure
- JavaScript and Python SDKs plus LiveKit and Pipecat integrations
- Tool calling and knowledge-base retrieval inside the conversation
- Free tier includes API access and a custom avatar, not just a watermarked demo
Cons
- Per-minute billing makes sustained usage expensive to forecast
- The free tier cuts conversations off at three minutes and one concurrent session
- The pricing page failed to render its monthly base fees, so the full paid cost is not legible
- No country or registered entity is published anywhere on the site
