NextChat

NextChat is an open source AI assistant platform for conversation, analysis, document work and multimedia creation. It gives access to many AI models from one interface and positions itself around two ideas: users can bring their own access credentials, or they can pay for usage with prepaid credits. There is no subscription requirement. Users sign in with an email code or a Google account. The platform covers everyday questions and writing help, reading and summarizing documents, deeper analysis of complex tasks, and image and media creation. Higher tier credit packs add dedicated access credential management and the ability to share credits among several people, which the vendor pitches at families and small teams. Because the project is open source, it can also be self hosted, and the vendor emphasizes that keys and data stay under the user's control. It is aimed at individuals who want one place to use several models without committing to a monthly plan, and at households or small groups who want to pool a balance. Pricing is pay as you go. Credits are bought as one time top ups of $8.00 for occasional use, $20.00 for frequent work, or $300.00 for shared workflows and intensive use, and they are spent across conversations, creation and analysis. A redeem code option is also available.
