The Engine for
Real-Time,
Probabilistic BCI.
Nimbus Personalizer and the SDK/API — freeze any encoder, adapt a cheap Bayesian head, and ship BrainState to apps. Built on RxInfer for latency, adaptability, and explainability.

When the factory breaks,
restore — ~23× cheaper.
Raw EEG through a frozen encoder. Stress collapses the factory head. A thin Bayesian Personalizer climbs back — without fine-tuning the trunk.
Raw EEG → frozen foundation trunk. Weights stay locked.

Fine-tune stays a priced escape hatch — not the default path.
Illustrative loop from exploratory BNCI stress protocols. Lead cost ~23× vs short fine-tune on locked bakeoff cells. Not an accuracy-SOTA claim — adapt when the factory breaks.
Freeze the trunk.
Personalize the head.
Nimbus Personalizer sits on any frozen encoder: cheap Bayesian adaptation and a thin BrainState for apps. Adapt when deployment stress breaks the factory — not when it already transfers. Head updates are about 30× cheaper than fine-tune under gated recovery.

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

& Application Areas
The Nimbus engine is designed to be hardware-agnostic, providing a universal processing layer for the entire BCI hardware landscape.
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 & 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.
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 (NimbusLDA, NimbusQDA, or NimbusProbit)
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))")Advanced Models & Applications
The Nimbus engine is a platform for building sophisticated, next-generation BCI systems, powered by a suite of state-of-the-art probabilistic models.
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.
For spectral analysis of neural oscillations. Crucial for rhythm-based control paradigms, sensorimotor applications, and steady-state visual evoked potentials (SSVEPs).
For modeling discrete brain states. Perfectly suited for applications like motor imagery classification, sleep stage analysis, or decoding distinct cognitive states with high fidelity.
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.
