The Operating System for
BCI Research
Built with the open research and AI stack.
Design BCI paradigms
by connecting blocks.
Sequence tasks, loops, and triggers on a visual canvas, no scripting.
Pictures, sound and words
on the recording’s clock.
Every stimulus is timed to the signal, so a trial’s media, data and label always stay together.
From raw signal to activation map.
Preprocess with MNE, add your own custom filters in Python, and generate 2D activation maps and 3D cortical renders, all from the same pipeline.
Preprocessing with MNE
Standard filtering and preprocessing pipelines on MNE foundations.
Custom filters in Python
Drop in your own filters and transforms with plain Python.
2D & 3D activation maps
Generate topographic maps and 3D cortical renders from the results.
Whole-brain activation map
Reconstructed activity projected onto a 3D cortical mesh for spatial localization of the response, built on the same MNE-derived source estimates as the 2D views.
Time-resolved scalp maps
Channel-wise concentration changes plotted across the epoch, from baseline to peak response.
Per-channel waveform overlay
All channels overlaid against a synchronized topographic snapshot at the selected timepoint.
Every analysis step, one workspace.
Preview any step on one file, then batch-apply across the whole dataset, every output drops straight into ML Flow.
- 1Apply to one file
- 2Check the result
- 3Batch-apply to all
- 4Import into ML Flow
Build model pipelines
block by block.
Drag, connect, and run from raw signal to a scored model.
Get unstuck
while you work.
AI that understands your project.
From logistic regression to EEG transformers.
The desktop Components Library, mirrored. Every ecosystem, model family and pipeline stage on one palette — drag it onto the ML Flow canvas, or rewire it by hand.
Classical ML
Fast, interpretable baselines. Every serious BCI result starts by beating these.
scikit-learn
Pipelines, CV, the classics
XGBoost
Gradient-boosted trees
Drops into ML Linear, ML Ensemble, ML Neighbors & ML Clustering blocks

Choosing the model is the easy part.

“It worked on subject 1”
Domain Adaptation
A decoder rarely survives a new head, or a new day.
“Session 6 broke session 1”
Domain Incremental Learning
Training on new data quietly erases what the model already knew.
“94% accurate, on what?”
Uncertainty & Evaluation
An accuracy number cannot say when the decoder should decline to answer.

Every experiment is a versioned workspace.
Create, save, duplicate, and compare experiments inside a project, each with its own version, run history, and lineage.
“Highest mean” is not a finding.
A second tab on the Results page tests whether a difference is real.

On every result
The analysis we did not build.
No tool draws every chart a reviewer asks for. Take every table out as CSV or Excel, or write the analysis in the app with the results already loaded.
per_subject = (results[results.metric == "accuracy"]
.groupby(["pipeline", "subject"])["value"].mean())
summary = per_subject.groupby("pipeline").agg(["mean", "std"])
fig, ax = plt.subplots()
ax.bar(summary.index, summary["mean"], yerr=summary["std"], capsize=5)Right-click: PNG at 300 or 600 dpi, SVG, PDF, copy, zoom — the same menu as every other chart in the app.
Already loaded in every cell
Data opens a reference onto your own study: every name, every column, and a real value out of it. validation is the same module the Results Validation tab runs on.
Nine tables, one join key
Every row carries experiment_id, so the tables rejoin anywhere.
- observationsone row per every stored score
- parametersone row per every configuration value
- runsone row per training run
- experimentsone row per experiment
- metricsone row per experiment × metric
- modelsone row per trained model
- reproducibilityone row per hashes, seeds, versions
- versionsone row per version-history entry

The starter notebook already runs: it loads the CSVs, plots them, and runs a paired test across your subjects.
