Nightcap is a browser-based platform for adults aged 18 and older to meet new people through free, one-to-one random video or text chats. Users can start without creating an account, downloading an app, or providing an email address. The service works on desktop and mobile browsers, and text chat is available without a camera. Matching can be random or guided by interests and, where available, preferences such as country.

Nightcap includes real-time video effects, including color filters, Beauty Mode, and adjustable AI background blur, processed locally in the browser. Automated text and video moderation operates during sessions, with tools to report violations and access to human review. Some users may encounter text-based AI chat companions, which are clearly identified as AI.

Basic chat is free. An optional, one-time Boost purchase offers queue priority and preference controls; it is not a subscription and does not guarantee a particular match. Nightcap also provides conversation prompts, daily challenges, and information about its rules, privacy practices, and safe use.
