TokBox allows users to start a multi-party video chat with up to 50 people. The platform does not require download for use and it is set up to allow the creator of the video chat to invite non-tokbox users into the call via email, instant messaging or by publishing the URL on their Twitter / Facebook / MySpace accounts. TokBox allows users to share YouTube videos within the video chat. Users can resize the YouTube video to appear larger and therefore the main focus of the video chat or can minimize the video. SlideShare, Flickr, Picasa and TokBox Video Mails can also be shared within the video call.

TokBox allows its users to send video messages. Video messages can be up to 10 minutes long and can be sent to another TokBox user or anyone with an email address.

TokBox also has its own IM client and users can import their Yahoo Messenger, MSN Messenger, AOL AIM and GChat accounts. From TokBox, users can then invite their imported buddies to video chats without their buddies needing to sign up for TokBox.

There is no hard limit to how many sessions you can create, however there is a limit to how many publishers and subscribers can be in a session. Here are some examples of what a session can support:
- 1 person publishing with up to 2,500 people subscribing.
- 3 people publishing with up to 800 people subscribing.
- Up to 50 people in a video chat together.

TokBox makes available a series of API for developers. The APIs allow other websites to embed the majority of TokBox features and functionalities (such as multi-party video chat, IM and Video Mail) in to their website.

TokBox lists Meebo, eBuddy, Digsby, InnovaHire, Radius IM and DabbleBoard as featured partners who use the API

Many people maybe need to record their interesting and precious moments to play it with any devices or keep it as souvenir, although Yahoo! Messenger disables recording video chat.
