Built on a Foundation of Proven Technology

The Nimbus engine is powered by RxInfer, the state-of-the-art reactive message passing framework for automated Bayesian inference. In partnership with Lazy Dynamics, the core developers of the technology, we are building the most performant and reliable software layer for the BCI industry.

How Nimbus OutperformsTraditional BCI Models

Our probabilistic approach fundamentally outperforms traditional BCI software across the metrics that matter most for real-world applications.

Broad Hardware Compatibility& Application Areas

The Nimbus engine is designed to be hardware-agnostic, providing a universal processing layer for the entire BCI hardware landscape.

EEG

Non-Invasive EEG

For devices like Muse, OpenBCI, Emotiv. Our engine excels at handling noisy, non-stationary signals from consumer headsets, using real-time adaptation to deliver reliable control for gaming, wellness, and neurofeedback applications.

Clinical

Clinical & Medical Devices

For clinical-grade EEG, ECoG, and assistive tech. Nimbus provides the "White Box" explainability and confidence scoring essential for regulatory approval (FDA/CE), powering the next generation of neuro-rehabilitation and diagnostic tools.

Implants

High-Bandwidth Implants

For microelectrode arrays like Neuralink & Synchron. Our high-performance architecture processes massive, high-velocity data streams with ultra-low latency, enabling advanced applications like high-DOF prosthetic control and communication.

Simple Integration,
Powerful Results

NimbusSDK.jl runs locally on your machine—no API calls during inference. Get from preprocessed EEG to probabilistic insights in just a few lines of Julia.

# 1. Setup with your API key
using NimbusSDK
NimbusSDK.install_core("YOUR_API_KEY")

# 2. Load pre-trained model (RxLDA, RxGMM, or RxPolya)
model = load_model(RxLDAModel, "motor_imagery_4class_v1")

# 3. Run inference with uncertainty quantification
data = BCIData(csp_features, metadata, labels)
results = predict_batch(model, data)

# 4. Analyze with full confidence scores
println("Accuracy: $(mean(results.predictions .== labels))")
println("Confidence: $(mean(results.confidences))")
1. Install SDK
One-time setup with your API key
2. Load Model
Choose RxLDA, RxGMM, or RxPolya for your BCI paradigm
3. Run Inference
Get predictions with full uncertainty quantification in <20ms

Advanced Models & Applications

Explore the Full Model Library

The Nimbus engine is a platform for building sophisticated, next-generation BCI systems, powered by a suite of state-of-the-art probabilistic models.

State Space Models (SSMs)

For modeling latent brain states over time. Ideal for handling noisy observations from EEG, MEG, or spike trains, providing a robust foundation for continuous decoding and control.

Autoregressive (AR) Models

For spectral analysis of neural oscillations. Crucial for rhythm-based control paradigms, sensorimotor applications, and steady-state visual evoked potentials (SSVEPs).

Hidden Markov Models (HMMs)

For modeling discrete brain states. Perfectly suited for applications like motor imagery classification, sleep stage analysis, or decoding distinct cognitive states with high fidelity.

Kalman Filtering

For real-time tracking and decoding. The gold standard for estimating continuous variables from noisy signals, enabling fluid control of neuroprosthetics, cursors, and other dynamic systems.
