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. Paid plans run from $12 to $999 a month with included minutes plus per-minute overage, which suits demos and pilots but adds up fast 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 custom avatars, not just a canned demo
Cons
- Overage billed per minute ($0.16 down to $0.11) makes sustained usage hard to forecast
- The free tier cuts conversations off at three minutes, allows one session at a time and excludes commercial use
- Removing the embed watermark starts at the $49 Explorer plan
