Cactus: On-device AI for Smartphones, Laptops & Edge

Cactus is a hybrid cloud and on-device AI toolkit that allows developers to deploy speech, vision, and text models. Powered by the Cactus Engine, it automatically routes tasks between on-device processing for simple operations and cloud processing for complex or noisy data, optimizing for both accuracy and cost.

Key Features

• Hybrid Routing: Automatically routes audio and commands between on-device and cloud based on complexity and audio quality, handling over 80% of production transcription and LLM inference on-device.
• Optimized Execution & Memory: Features quantized models with hardware-specific acceleration for battery-efficient inference, alongside zero-copy memory mapping for minimal RAM usage and near-instant model loading.
• Cross-Platform SDK: Write once and deploy across iOS, Android, macOS, and wearables.
• High Performance: Delivers under 120ms on-device latency and under 6% Word Error Rate (WER) for transcription.
• Privacy Controls: Offers the ability to lock transcription to on-device only, ensuring audio data never leaves the device. It is HIPAA-friendly, GDPR-compliant, and features zero data retention.
• Open Source: The Cactus Engine is fully auditable and community-driven, allowing developers to inspect the code running on user devices.

Use Cases

• Mobile Voice Assistants: Real-time voice commands and dictation for iOS and Android applications.
• Desktop Notetakers: Meeting transcription and note-taking for macOS, featuring automatic speaker detection.
• Wearable Intelligence: Always-on transcription for smart glasses and AR devices with minimal battery impact.

Pricing

Cactus is free to start and scales with usage. It also offers a free cloud fallback promotion for the month of March.
