Neuromarketing research in your web browser

RealEye is a cloud-based solution for neuroscientists to simplify their work. It allows creating experiments, tracking participants, and analyzing the data - all in one place, online.

Create your study in a web browser. Access your dashboard any time, any place.
    • Provide your stimuli as a set of images, videos or a live website.
    • Create up to 60 minutes long studies.
    • Set a display time, view type, custom instructions for each item.
"Trigger" will let the panelist finish the display of the stimuli after clicking a specified hotspot or after a keystroke - you can also set display time manually.
Enable survey after each stimuli, ask different types of questions, analyze & export results for single participant and aggregated
Redirect participants to any URL after the test

"Webcam-based eye-tracking has vast potential within market research and RealEye made a great effort customizing their solutions to our needs. We succeeded in having live online interviews with eye-tracking included and we look forward to build on this pilot study to take further advantage of this solution in future research."

Stefan Papadakis
Insight Consultant, IPSOS

"I'm really impressed with what Adam has created with RealEye. It's astounding how easy and fast it is to track and report on eye movement for a page or design."

David Darmanin

"With RealEye, we found users weren't noticing key parts of our value proposition, that we couldn't have discovered with screen recordings or heatmaps. This service is invaluable and even better.....affordable."

Lewis Healey
UX Designer,

"“I work on usability testing projects on a regular basis and I’m so glad that we have found RealEye! I have thoroughly enjoyed the impeccable customer service that Adam’s team has provided. They are friendly, accommodating, and responsive to our questions and concerns. The product serves our needs well and it’s constantly improving. It really makes remote testing possible and convenient"

Frequently Asked Questions

How accurate are the eye-tracking results?

RealEye studies are proven to be around 110 px accurate. This allows analyzing users interaction on a website with precision reaching the size of a single button.We predict the gaze point with frequency up to 60 Hz.For in-depth analysis of webcam eye-tracking accuracy check the following articles:

How does online webcam eye-tracking work?

Webcam eye-tracking is an innovative method that predicts a person's gaze point.We use the computing power of regular PC/laptop to run AI (Deep neural network) that analyzes images coming from a webcam. The AI detects a panelist's face, pupils and predicts a gaze point.All of this is performed entirely in a web browser in real-time. Thanks to this, panelists do not have to worry about their privacy. We do not send any image or sound to our servers. We only store the gaze point predictions from our AI, in the form of basic text data similar to "Timestamp: 10, GazePointX: 200, GazePointY: 330".

You can read more about eye-tracking here .

Who can participate in my study?

Either your own or RealEye participants. You can invite your users or panel and share the study with them using a participation link. All they need to have is a laptop/PC with a webcam.We also have a network of panelists from all over the world - mainly from the UK and the US. Randomly picked users can be assigned to your task. They are called RealEye participants. We will not show them your stimuli before the test starts, so their interaction will be natural.

Note: RealEye participants can't take part in a 'Live Website' studies and studies longer than 10 minutes. Read more about the limitations here.

What’s the difference between own and RealEye panelists?

Your own participant is any person that you’ll invite using a participation link to your study. RealEye participant is a randomly picked person from our network of panelists from all over the world - mainly from the UK and the US. They can be hired to participate in the eye-tracking study, but not to participate in any external tool (eg. survey).

Note: RealEye participants can't take part in a 'Live Website' studies and studies longer than 10 minutes. Read more about the limitations here

Can I get more participants?

You can get additional participants at any time you need it. This will increase your limit in the current billing period only. Each additional slot for an own participant costs $1.2. Hiring Realeye participants is only $10 each.

When you order RealEye panelists, we make sure to provide the highest quality results. All recordings are checked by us to make sure that you get results with an accuracy of fewer than 175 pixels and at least a 20 Hz sampling rate. Assuring high-quality results usually requires us to pay for and check more panelists than you've requested, but we take that cost on us - so you pay only for the best results.

What equipment or setup does RealEye require?

How to track panelists?

To connect external tool (eg. survey) and test results with a participant you will need to modify your test recruitment link to pass in the variables you want to track. The panel provider must add the variables (different for every panelist) to the RealEye URL dynamically.

You can add custom variables to your recruitment link using a ? (question mark) and join multiple variables using an & (ampersand).

For example, if the study link is
then you need to add parameters like this:

In this example 2 variables were added: user and company ID. This allows you to track who completed your test and match the results with results from an external tool while exporting data.
If you pass a variable called 'realeye-participant-external_id' - the value of this variable will be visible on the results dashboards next to participant demographic data.

Can I export the data to CSV (or any other format)?

Yes, you can download the data collected during the study as a CSV file. For more details please refer to

Also, you can download each AOI CSV file.

If there’s any data that you would like the CSV file to include, please contact us and we’ll provide any additional data.

Do you provide emotional analysis?

Yes, since version 6.10 RealEye can also collect and store basic information about Facial Coding. You can check the entertainment level in time for each of the participants and in the aggregated way. This is very useful for testing video advertisements.

Do you provide Eye-Tracking Reports?

Our tool doesn’t generate reports. As a result you’ll receive gaze and mouse recordings, heatmaps with an AOI tool and CSV files (including the AOI data). You can download all the data you need: heatmaps as a PNG file, recordings as an MP4 file and the CSV file, easily translated into an excel file.

Can I pay per study?

There are only monthly payments, so there’s no possibility to pay per study. But keep in mind that you can cancel your license any time (even in the same month) - you’ll keep the account access until the end of the billing period (30 days from the last payment).

Can I integrate RealEye with other tools?

You can easily integrate the RealEye tool with external tools (eg. surveys), but also compare the results obtained from other tools using our CSV file (i.e. by the timestamp).

Can I test live websites?

Yes, you can test live websites with no need to include any scripts or code on the tested websites.
