The task setup is already done.
Spend your time on the research question. Inspect the methods before deciding whether a task fits your protocol.
Free, from setup to export
Create a study link and download the results without paying for access.
43 documented tasks and questionnaires
Classic paradigms alongside skill tasks and self-report measures. Read the trials, scoring, differences from the original and references on each methods page.
161 instruction languages
Word-based tasks use material made for the language where available, rather than simply translated English word lists. The dashboard shows the tasks available in your chosen language.
Every trial, ready to analyse
Export CSV or JSON with participant codes, responses, timing, task versions and scores. Go beyond the final score.
A focused participant experience
Study mode has no sharing buttons, public comparisons or ads. Participants follow your selected task order and return to your survey.
Consent stays in your workflow
Keep information, consent and any ethics approval with your own survey or study platform. Send participants to the tasks only after that step.
Separate study data
Study results stay separate from public player results and norms. Delete a study and its data in the dashboard, or request deletion. Optional contributions of anonymised aggregates are off by default.
Versions you can cite
Exports record the task versions used. Each methods page supplies a citation and original references. The methods document has a Zenodo DOI.
From survey to results in three steps.
Create your study
Sign in and confirm your email. Choose the language, add supported tasks in order, and set the completion URL. Create the study and copy its participant link.
Add the link to your survey
After consent, redirect participants to the study link. Pass an assigned code with ?pid=P001, replacing P001 for each person. After the last task, Helibrain returns them to your completion URL with the same pid; other URL parameters are preserved.
Download your data
Open your dashboard and download CSV or JSON. CSV has a row for each trial; JSON also includes study settings. Match the participant code to your survey responses.
Participant link format
https://helibrain.com/s/YOUR_STUDY?pid=P001Keep the code-to-person key yourself. Use assigned codes, not names or email addresses. Codes must contain a letter and a digit; the dashboard link includes an example.
What the export looks like
These are actual column names and sample values from a local reaction-time study with simulated participants. This is a subset of the CSV, not a list of fields invented for this page. Responses and metrics vary by task.
| participant_code | task_code | task_version | language | section | trial |
|---|---|---|---|---|---|
| P005 | reaction_time | 1:231f48fef1dbceaa | en | reaction_times_ms | {"index":0,"value":372.0} |
| P005 | reaction_time | 1:231f48fef1dbceaa | en | reaction_times_ms | {"index":1,"value":518.0} |
| P005 | reaction_time | 1:231f48fef1dbceaa | en | reaction_times_ms | {"index":2,"value":587.0} |
The full export also records task start and submission timestamps, configuration, device type, trial responses and task metrics. Times keep their original field names and units. Pilot the tasks and inspect the export before collecting your study.
Know the limits before you collect.
Browser timing includes the device
Screen refresh rate, browser scheduling and input hardware add delay and variation. A millisecond value in an export is not a guarantee of millisecond accuracy. Read the reaction-time timing notes and screen refresh-rate notes. Keep device and browser conditions consistent where your design needs this.
Online participation is unsupervised
Distractions, practice, comprehension and device differences can affect performance. Pilot your protocol, define exclusions in advance and check trial-level responses.
Validation is planned, not published
These implementations differ from established tests. Validation against established tests is planned and has not yet been published. The tasks are for research and demonstrations, not diagnosis, treatment or clinical decisions.
Questions before you start
What does it cost, and are there usage limits?
Study links and CSV/JSON exports are free. The Research Terms promise no fixed usage quota. The dashboard currently enforces study and participant caps, and service protections can slow or pause use. Check the dashboard and contact us before planning a larger study.
Who handles ethics approval and participant consent?
You do. Give participants information, obtain consent and arrange any required ethics approval in your own survey or study platform before sending them to Helibrain. You decide whether a task is suitable for your protocol. Read the Research Terms before collecting data.
Which survey tools can I use?
Any survey tool that can redirect to a URL with a participant-code parameter. Send the assigned code as ?pid=P001 on the study link, replacing P001 for each person. Set an HTTPS completion URL when creating the study; after the final task we append the same pid and preserve its other parameters. Participants do not need a Helibrain account.
Where is study data stored?
Study data is stored on servers in the United States. If your institution requires EU storage, contact us before collection; EU hosting can be arranged for larger studies. See the Research Terms for the processing agreement and transfer clauses.
Can I delete study data?
Yes. Delete the study and its participant data in your dashboard, or contact us with a deletion request. Export anything you need first. Backup copies are removed when the backups expire. Study results stay separate from public player results and norms; optional aggregate contributions are off by default.
Which languages are available?
Task instructions are available in 161 languages. Tasks that need words, passages or other language-specific material appear in the dashboard only where that material is available. Check each methods page for its language material and review status; do not assume every translation has been reviewed by a native speaker.
How should I cite Helibrain in a paper?
Use the citation on each task’s methods page, report the task version from your export, the language and your collection dates, and cite the original task papers listed there. For the methods document, use the Zenodo concept DOI 10.5281/zenodo.24052521.
How accurate is reaction-time measurement?
Timing uses the browser clock and includes display and input-device delay. Accuracy varies across devices and browsers. Read the reaction-time limitations and refresh-rate notes, pilot on your target devices and assess whether that precision fits your research question.
Are these validated tests or clinical assessments?
No validation of these implementations against established tests has been published; that work is planned. The methods pages explain differences from the classic tasks. Do not use the tasks for diagnosis, treatment or clinical decisions.
How can I discuss a study or ask for help?
Email hello@helibrain.com with your research question, the tasks and languages you need, and any hosting requirements. Contact us before collection if your institution needs EU storage or your study needs more capacity.

Data quality flags
Study exports keep browser, operating system and available device model, screen and viewport sizes, display timing, and time away for each task run. Leaving or hiding the page, losing window focus, copying, cutting, pasting, text selections, context menus and delivered PrintScreen key events are counted. Clipboard contents and selected text are never recorded. Answer rows include time since the last return when it can be matched to the trial.
Flags point out time away, unusually fast or repeated answers, accuracy at or below a defined chance level, unreliable display timing, incomplete runs, copying, pasting into an answer field, a screenshot key and answers soon after returning. They are information for review: no flag removes a row or changes a score. JSON metadata gives the column dictionary and exact rules and thresholds; missing or inapplicable measurements are blank in CSV and null in JSON.
A browser cannot see screenshots taken on phones or Macs, a second device, or some in-browser side panels. These signals cannot establish whether someone used outside help.
