Frequently Asked Questions
Sayna vs Presto Voice: which should you choose?
Choose Presto Voice if you run a QSR chain and need a turnkey drive-thru solution with proven upselling ROI. Choose Sayna if you're a developer building custom voice agents and want a flexible, API-first abstraction layer to avoid vendor lock-in. They serve different markets—one is a finished product for restaurants, the other is infrastructure for AI engineers.
Can Presto Voice work for non-drive-thru restaurants?
Presto Voice is primarily designed for drive-thru operations. It includes phone ordering automation, but its core focus is drive-thru, so dine-in or delivery-only restaurants may not get full value.
Does Sayna provide pre-built voice agents?
No. Sayna is an infrastructure layer for adding voice capabilities to your own AI agents. You still need to build or bring your own LLM/agent logic.
Which product is easier to start with for a non-developer?
Presto Voice is easier: it's a turnkey solution with installation support. Sayna requires coding and agent development, so it's for developers.
Can Sayna handle drive-thru noise?
Sayna supports multiple STT providers and noise filtering via VAD. With the right models, it can be used in noisy environments, but it doesn't offer a tailored drive-thru solution like Presto Voice.
Do Presto Voice and Sayna integrate with each other?
There is no official integration between the two. They serve different markets and are unlikely to be used together directly.
What pricing model does Sayna use?
Sayna's pricing is contact-based but typical of API platforms: likely usage-based (per minute of audio). Exact tiers are not public.
Does Presto Voice support languages other than English?
Presto Voice's multi-model approach can handle diverse accents, but specific language support is not detailed. Contact them for details.
Is Sayna open source?
No, Sayna is a proprietary API. However, it provides SDKs in multiple languages and works with open-source agent frameworks.
