Core Features
On-Device AI SDKs
Production-grade, self-contained SDKs for voice, language, and vision that run entirely on-device, eliminating cloud dependency, network latency, and privacy concerns.
Voice Activity Detection
Catches speech in noisy, real-world conditions with 12x fewer errors than Silero, using 9x less CPU.
Wake Word & Speech-to-Intent
Custom wake word detection and intent recognition that is personalized and always-on, with speaker recognition for security.
Streaming Speech-to-Text & Text-to-Speech
Real-time streaming transcription and synthesis for live captioning, translation, and voice assistants.
Speaker Recognition & Diarization
Identify and separate speakers in audio streams for meetings, call screening, and personalized experiences.
On-Device AI Stack (picoGym, picoCompression, picoInference)
Full-stack on-device AI: model training, compression without accuracy loss, and a purpose-built inference runtime for edge devices.
AI App Blueprints
Open-source, production-ready demo projects for voice assistants, translation, RAG document QA, and more, showing end-to-end integration.

Pros and Cons
Pros
- On-Device PrivacyAll AI processing happens locally on the device, keeping user data private and secure without needing cloud infrastructure.
- Low LatencyReal-time voice and vision understanding with no network round trips, enabling instant response and always-on capabilities.
- Cost PredictabilityNo unbounded cloud costs; fixed per-device pricing (free trial or enterprise) eliminates variable usage expenses.
- Purpose-Built OptimizationFull pipeline from training to inference is architected for on-device execution, outperforming retrofitted cloud models in accuracy and efficiency.
- Production-Ready SDKsSelf-contained, easy-to-integrate SDKs that reduce development time from months to hours, with open-source demo code and blueprints.
Cons
- Limited Compute ResourcesOn-device AI is constrained by device hardware; complex models may not run on very low-power devices without optimization.
- Integration EffortWhile SDKs are self-contained, developers still need to integrate multiple modules for complex features, requiring some development expertise.
- No Public PricingEnterprise pricing is not transparent and requires a sales call, which may be a barrier for small teams or individuals evaluating the platform.
- Free Trial LimitationsThe free trial likely has usage caps or limited features, and scaling to production requires moving to a paid plan.
- Dependence on Device EcosystemOptimal performance may vary across different devices and operating systems, requiring thorough testing and customization.
