Once the participant completes the experiment, their data will be automatically uploaded to your account. To access E-Prime Go, simply register your E-Prime 3.0 serial number on our support site to download the E-Prime Go application.
Drag and drop design.
Build experiments with text, images, sound, and videos by dragging and dropping objects onto your timeline. Take advantage of free templates and 100+ pre-built experiments in our Experiment and STEP Libraries.
Timing accuracy
E-Prime 3.0 reports timing accuracy to the millisecond precision level. Be sure to use our testing tools to confirm your computer hardware is capable of critical timing. Add Chronos to your research setup to verify the display timing of your monitor, obtain millisecond-accurate participant responses, as well as millisecond-accurate sound onset times.
Unlimited Data Collection.
Collect unlimited data in the lab with E-Run and remotely with E-Prime Go! E-Studio provides descriptive menus and intuitive data logging options. E-DataAid provides the tools to filter, analyze, and export your data.
Hardware integrations
Use Task Events to send and receive triggers through Chronos, socket, serial, or parallel port. Use Chronos Adapters for a simple connection to a wide range of EEG, fNIRS, and physiological devices to send and receive digital triggers. If you are using a wireless EEG system, we also have an E-Prime package file for LSL hosted on GitHub.
Dedicated support team
We have a dedicated team of technical consultants available to assist you with experiment setup, troubleshooting, and best practice tips. Submit a support request on our support site.

Customer Testimonials
Your staff, from the technicians to customer support, are always eager to help, and go far beyond good customer service. Your technicians have helped me trouble shoot both over email and over the phone, and always take care to thoughtfully explain it in a way I can understand. Your customer service has been very receptive to my requests, such as requests to watch certain webinar videos. Needless to say we are happy gold members with E-Prime!
The customer care service is excellent - I have received very prompt and detailed responses to all my questions.
I have to thank YOU and the team for your quick reactions, for taking my problems seriously and for not giving up looking for possible solutions. As a customer one does not encounter that so often. If all support teams all over the world would be like you, PC life would be a bit easier! At the moment I have no more questions. I am very happy to use E-Prime now on my own PC!
Staff made several response on the very day that I posted request, helping with a problem that in the end did not even belong to PST. Going above & beyond duty, highly satisfied.
I have contacted PST support several times when faced with problems with an experiment I have been designing for the past six months. Each time, they have been quick to respond and have been incredibly helpful. They offer suggestions and even looked through my program to find out the problem. I am not sure I would have fixed this latest problem with markers showing up inconsistently without the help of the PST Support team. The customer service received from PST is by far the best I have ever experienced when working with any product or software. I wish the product support for all of the programs I have to use to do research were as excellent as the PST support. I greatly appreciate all of the help with my program. Whether it be a mistake I made or something as simple as un-checking a box in an object, they always help me when I am the most frustrated with problems arising when conducting an experiment. Thank you PST Support Team!
The best part of the deal is the support staff. They're extremely helpful and knowledgeable. And friendly! I almost look forward to problems coming up!
This was the first time I'd contacted PST support and I expected - based on experiences with other support teams - that I'd get a generic, auto-generated response. I was very pleasantly surprised to receive (very quickly!) a personal email from Devon, who addressed the issues I was having and offered suggestions for how to fix them. When I didn't understand all of the suggestions, he wrote back and clarified and was very patient throughout the experience. I am so grateful to have had such a nice experience with your support staff. Ultimately the problem was resolved and I am very thankful for the help I received from Devon. THANK YOU!!!
We are always happy when working with PST. Everything is working very well!
I have been using E-Prime for 10 years now. Your technical support has always been and continues to be the most helpful support with which I have ever interacted. Thank you for the great work that you do!
I'm very impressed with the quality of response I receive from PST. The technical consultants, particularly Devon, are amazing. My graduate students and I are very grateful for such excellent support as we learn e-prime.
This technology worked great. I did not experience any 'bugs' and headaches were kept to the minimum. Keep doing a great job!
