​
General

NeuroFusion is a research platform for designing studies, collecting behavioral and brain data, and analyzing results. It supports prompts (recurring surveys), jsPsych experiments, wearable integrations, and EEG recordings — all managed through organizations with built-in billing.
Researchers, clinicians, and study administrators in cognitive neuroscience, behavioral science, psychology, health research, education, and social sciences.
Signing up and creating organizations is free. New organizations receive bonus starter credits. Certain actions — publishing quests, participant joins, data submissions — consume credits. See Billing & Credits and the Pricing page for details.

​
Prompts

There are 5 response types: Yes/No, Text, Number, Number Range (with configurable min/max), and Custom Options (semicolon-separated, single or multi-select). See Response Types for details.
Each prompt has three scheduling dimensions: active days (which days of the week), time window (start and end time, defaults 8 AM–10 PM), and frequency (once, every 30 min, hourly, every 2/3/4 hours). See Scheduling.
You can configure a prompt to only send notifications if a participant’s answer to a previous prompt or onboarding question meets a condition. For example, “Only ask about caffeine if they reported poor sleep.” See Conditional Notifications.
There is no hard limit on the number of prompts, and prompts are no longer required to save a quest. You can create a quest with zero prompts or add as many prompts as your study design needs.
Question guards are server-side validation rules on onboarding questions that determine whether a participant is eligible to join a quest. For example, you can block participants under 18 by setting a guard: operator: gte, value: 18. See Question Guards.
Yes. Configure question guards on your onboarding questions. If a participant’s answer fails validation, they see a rejection message and cannot join the quest. This is enforced server-side.
Kiosk mode re-shows the onboarding flow (consent overview + questions) every session, even for participants who have already joined. This is useful for shared devices in labs, clinics, or events. See Kiosk Mode.
No. Both the full-text overview and onboarding questions are optional. A quest can have neither, one, or both.

​
Experiments

The experiment editor provides a default jsPsych 8.0.3 template with 13 pre-loaded plugins. You can write any HTML/JavaScript experiment that calls jatos.endStudy() to submit data. See Experiment Editor.
Yes. The media uploader supports JPEG, PNG, GIF, WebP, SVG (images), MP3, WAV, OGG (audio), and MP4, WebM, OGG (video). Maximum file size is 25 MB per file. See Media Uploads.
Yes. The Fusion mobile app (iOS and Android) supports running experiments in a WebView with automatic landscape orientation lock. Data is saved locally first and synced to the server. See Running on Mobile.
Yes. A quest can hold multiple experiments with defined ordering. Participants see a horizontal list of experiment cards and can complete them sequentially. See Ordering & Assignment.

​
Organizations

Any NeuroFusion user can create an organization. The creator automatically becomes the admin.
Yes. You can be a member of multiple organizations with different permission levels in each.
You need appropriate permissions on both the source and target organizations. Use the quest transfer feature in the org dashboard. See Managing Quests.
There are 18 granular permissions across 5 categories: Admin, Organization, Quest, Credits, and Data. See Members & Permissions for the full reference table.

​
Billing & Pricing

You can purchase credits in preset packages or enter a custom amount. Payment is via Stripe. See the Pricing page for current packages and the Purchasing Credits guide.
Publishing a quest, participant joins, prompt responses, experiment submissions, brain recordings, health data syncs, dataset storage, and data analysis. Quest creation and onboarding responses are free. See the Pricing page for current costs, or Expense Breakdown for per-quest tracking.
Yes. You can transfer credits to another org with an optional note. This requires the credits:transfer permission. See Funding Other Orgs.

​
Data & Privacy

Data is stored on Azure Blob Storage. Experiment data and brain recordings are stored as files in blob storage. Prompt responses and onboarding responses are stored in the platform database.
Yes. NeuroFusion adheres to GDPR, HIPAA, and other global standards. Researchers retain full control over dataset access and sharing permissions.
Yes. Data can be exported from the platform for analysis in external tools (e.g., R, Python, SPSS). On mobile, participants can export experiment data as JSON files.

​
Prolific

Use your quest’s run URL as the study URL in Prolific. No special configuration is needed — NeuroFusion automatically captures Prolific URL parameters (PROLIFIC_PID, STUDY_ID, SESSION_ID). See Prolific Integration.
Yes. All URL parameters are automatically passed to experiments via jatos.urlQueryParameters, so PROLIFIC_PID is included in your experiment data.

​
Mobile

The Fusion mobile app is available on both iOS and Android.
Yes. Experiments run in a WebView with landscape orientation lock. Data is saved locally and synced to the server. See Running on Mobile.
Yes. NeuroFusion integrates with wearables for health data collection (steps, sleep, heart rate) and EEG devices like Neurosity Crown and Muse. See Brain Interfaces and Wearables.
