• Already have an EventCAT account? Log in and proceed to “Conference Settings” below.
  
  

FAQ: Didn’t receive the OTP email?

Check that your email address is correct, refresh your inbox, and check spam/junk folders. If you still cannot find the email, refer to [Why Didn’t I Get My OTP Email from EventCAT?].

Step 2: Select an EventCAT Conference plan

• Prepaid Plan (Prepaid Pro): $40/hour
  This plan allows you to prepay for as many hours as you need and use them across multiple sessions. For example, if you purchase 5 hours, you can split them into several events, such as 30 minutes, 1 hour, or 2 hours each. Ideal for short workshops, lectures, or internal seminars that are held frequently. Supports up to 100 simultaneous connections to the real-time caption page and includes features such as Glossary, Transcript, and Meeting Summary.
• Half-day Pass: $300 / 6 hours
  A one-time pass for events lasting up to 6 hours. Suitable for half-day forums, seminars, or training programs. Supports up to 300 simultaneous connections to the real-time caption page and offers advanced features, including caption overlay, and the ability to insert a company or event-specific logo in the top-left corner of the caption viewing screen.
• All-day Pass: $600 / 24 hours
  Allows full access for 24 hours, including rehearsal time, and is suitable for medium to large events that run all day. Ideal for large international events or global corporate annual events (summits). Supports up to 500 simultaneous connections to the real-time caption page and includes all Half-day Pass features, plus customized on-site support from the EventCAT technical team (travel costs separate).
• Customized Plan
  For large-scale events (e.g., 500–10,000+ participants), multi-day continuous events, live streaming, or simultaneous support for multiple languages, a customized plan can include real-time caption screen customization (line spacing, maximum number of caption lines, etc.), advanced glossary training, and pre-event rehearsal setup and on-site support from the EventCAT technical team. For inquiries, email contact@eventcat.com to receive detailed consultation, references for custom events of various scales and fields, and online demos.

Important Notes
For Half-day and All-day Passes, once you click “Start Session,” the pass is activated immediately, and the usage time begins. Even if you click “Stop Session” to temporarily pause, the usage time continues from the initial activation. In other words, a single 6-hour or 24-hour pass cannot be split across multiple days.

• Choosing the right EventCAT plan for your Conference

• Which plan should be used for large-scale events with 500 or more participants?

• Which payment methods are supported?

• I want to provide translated captions simultaneously on both an on-site event and a YouTube live stream—can this be done?

• What is the Glossary feature, and how do I set it up?

• Can I customize the screen layout or add a logo to match the event concept?

• Does the price vary depending on the number of translation languages?

With EventCAT Conference, you can:

• Try the service before purchasing a paid plan with the “Free Trial”
  

• After purchasing a plan, create a session, set the languages, and use real-time interpretation in the “Conference Room”
  

• After the free trial, purchase a pass to continue using real-time translated captions.

Step 3: Should I use “Free Trial” or “Conference Room”?

After signing up and logging into EventCAT, you have two options:

• “Free Trial,” which allows you to set languages and test in real time immediately

• “Conference Room,” which lets you preconfigure real-time interpretation settings.

If you haven’t purchased a pass yet, you can test for up to 10 minutes in the “Free Trial.” If you have purchased a pass, you can create a conference room and a session, then test in “Rehearsal Mode” without using any of your pass time.

“Free Trial” – Ideal for first-time EventCAT users who want to test the service. 

You can select the spoken language and the translation languages for a simple test. To properly evaluate translation performance, you can use a voice file or script, create a glossary, and add it to the test session. If you want to check the accuracy of specialized terminology, be sure to use the glossary during testing.

“Conference Room” – Used when delivering real-time interpreted captions for an actual event.

EventCAT Conference is especially useful before setting up the Conference Room in the following situations:

• When multiple sessions over several days require real-time translated captions
  
  

• When different languages must be displayed simultaneously in separate locations
  
  

• When each session has speakers and audiences using different languages, requiring unique caption language settings
  

For example, international forums, academic conferences, or seminars often span multiple days, with each session featuring speakers and audiences using different languages. By pre-setting the caption languages, glossary, and caption visibility for each session, you can operate the caption service more systematically and reliably.

1) How to use “Free Trial”

This feature allows you to test EventCAT Conference for 10 minutes to see how it operates and how translations appear.

1. You only need to select the following two languages to start real-time interpretation immediately:

• Presentation Language: the language spoken by the presenter

• Translation Language: the language in which captions will be shown to participants
  
  

2. Click “Create and Next” to move to the controller page, where you can configure and review session and caption settings.

On the controller page, you can set and check the following items:

1. Left Sidebar
   
   

• Check Speaking Language (the language spoken by participants) and Target Language (the language for captions)
  
  

• Confirm whether the Glossary is applied
  
  

• Preview link and QR code provided (only supported in “Anyone can access” mode)
  
  

  • URL: Share on YouTube, KakaoTalk open chat, website, etc., so participants can choose their preferred language and view real-time translated captions
    
    

  • QR Code: Insert into venue screens, brochures, etc., allowing participants to scan with their phones or tablets and view real-time captions in their preferred language on their own device
    
    

• Live View: Page to display real-time captions on the actual event screen
  
  

• Edit Session: Allows changes to session languages, glossary, etc.
  
  

  • Note: The Edit Session button is disabled while a session is in progress. To make changes, click Stop Session to temporarily pause real-time captioning, then edit the settings
    
    

2. Right Sidebar
   
   

• Set up audio input (microphone)
  
  

  • Ensure your laptop microphone or external microphone is properly connected
    
    

  • To allow the EventCAT AI interpreter to hear your voice and provide accurate real-time captions, confirm that the laptop’s built-in microphone or wired/wireless microphone picks up your voice clearly
    
    

• Start Session
  
  

  • Click the Start Session button at the top right to have EventCAT translate the audio received through your microphone in real time
    
    

• Post-Session Features
  
  

  • After ending the session, the Download Transcript and Summarize Session buttons on the right sidebar become active, allowing you to download session summaries and language-specific caption transcripts
    

Notes:

• Using EventCAT in noisy environments may reduce the accuracy of real-time captions, as the AI interpreter may not recognize speech clearly. It is recommended to use a quiet environment and a reliable microphone, such as a laptop mic, AirPods, or an external microphone
  
  

• The speed of real-time captions depends on your laptop/computer’s internet connection. Wired internet provides more stable captioning than hotspots or public Wi-Fi

2) How to use “Conference Room”

After completing testing through the Free Trial and purchasing a pass, set up the event sessions that require translation in the Conference Room.

In international forums, academic conferences, seminars, or educational workshops, each session may have different spoken languages and target caption languages. By creating multiple sessions in the Conference Room and pre-setting the language pairs and glossaries for each session, you can operate real-time captions more accurately and reliably on the event day.

How to set up in the Conference Room 

Each Conference Room must be assigned one paid pass. Therefore, purchase a pass according to the scale and duration of your event, and follow the guide below for setup.

Check the EventCAT Conference Quick Start Guide for step-by-step instructions.

Before activating your pass, make sure to verify your audio setup and translation accuracy through Rehearsal Mode. Refer to the guide below for details on how to run a free test using Rehearsal Mode.

Tips for Successful Real-Time Caption Use

If this is your first time using real-time captions, we recommend doing an internal rehearsal or pre-test before the event day. You can use the 10-minute free trial or Rehearsal Mode to run a full test, including:

• Creating sessions and setting languages for each date and location
  
  

• Checking microphone connections
  
  

• Verifying preview screen display or QR code sharing methods
  

Testing in a setup identical to the actual event, with the same microphones and speakers, ensures smoother and more stable caption operation on the event day.
