Both put a talking avatar in front of your visitors. They are priced differently, built for different buyers, and one of them is ours. Prices below came from their own pricing page on 2026-09-18.
The short answer. Spatius sells the avatar's rendering; Smara sells the whole conversation, with the transcription, the language model and the voice included. Among the complete products we compared, Smara has the lowest price per minute on every plan.
| Product | Plan | Per month | Minutes | Per minute |
|---|---|---|---|---|
| Smara | Starter | $29 | 400 | $0.073 |
| Spatius | Starter | $16 | 2,000 | $0.008 |
| Smara | Growth | $99 | 1,800 | $0.055 |
| Spatius | Growth | $119 | 18,000 | $0.007 |
Their price covers avatar rendering. Ours covers the whole conversation, so these are not comparable numbers without adding your own model and voice costs on top of theirs.
Real-time avatar infrastructure you build on. The per-minute price buys the avatar rendering; their own writing describes the product as bring your own LLM and text to speech, so the language model, the voice and the transcription are yours to add and to pay for.
A low list price for rendering alone, and generous concurrency and session lengths at every tier. If you are building your own product and already pay for your own models, voice and transcription, their rendering price is worth a look.
Ours is a finished assistant rather than a rendering layer. The $0.073 includes the transcription, the language model, the voice and the avatar, plus the widget, the teaching tools and the dashboard. Comparing $0.008 with $0.073 compares a component with a product.
Underneath, the thing that makes our price possible is that the engine runs without a GPU. That is also why the same software can run inside a clinic or a law firm's own building, why the stream fits a 100 kbps connection, and why we can charge four cents for an extra minute rather than thirty-seven.
She can also operate the page she is on: point at what she is describing, fill in a booking form from what you told her, and finish the job rather than describe it.
Where we are weaker: we are newer, we are one product rather than a platform, and if you need a hundred simultaneous conversations today, several of the names here have been doing this longer.
You have engineers, you already run and pay for your own models, voice and transcription, and you only need the avatar's rendering.
You want an avatar on a normal business website that greets visitors, answers their questions and completes tasks, installed with one script tag, at the lowest running cost per minute of any complete product here.
