evenfall is a private AI chat application that provides direct, streaming responses without advertising, tracking, or data collection. The service operates on a model where conversations are encrypted individually within the database, with each conversation using its own encryption key stored separately from the data. Users can delete conversations permanently from the database with no soft delete, shadow archive, or recovery period. The application does not include third party trackers, ad pixels, or cross site profiling, and relies only on authentication and billing systems necessary for service operation. Payment processing is handled through Stripe for card payments, which provides only a customer ID and status to the service, while cryptocurrency payments are processed through NowPayments for one time passes without requiring personal information. The application includes several features designed for efficient interaction. Responses stream tokens as they are generated, rendering markdown and code blocks live with syntax highlighting and copy to clipboard functionality. Conversations are automatically titled after the first exchange and can be renamed, archived, or deleted from the sidebar. Per conversation instructions allow users to set the tone for each thread without maintaining a global configuration. The interface supports keyboard navigation with enter to send and shift+enter for new lines, and sidebar and settings are accessible without leaving the keyboard. Voice mode is available on the Pro plan, providing real time voice conversations with one hour of talk time per month. The application also supports immersive roleplay and storytelling with four ready made personas for roleplay, code, writing, and study, and paid plans allow users to build custom personas with their own instructions, opening lines, and portraits. Typical use cases include code reviews, research, creative writing, and general question answering. The workflow begins with email one time code or Google authentication, which takes under ten seconds. Conversations are created on the first send, with nothing empty saved. Users can attach pages for reading only when explicitly requested, with zero page access out of the box. The application offers limited daily messages on the free plan, with increased daily messages, web search with sources, image and file attachments, and custom personas available on paid plans. Card subscriptions are simple monthly plans with one click cancellation and access maintained until the billing period ends, with no contracts or lock in. The service is accessible via a browser extension that opens on any site using a keyboard shortcut or toolbar button, and allows right click actions to ask, translate, summarize, or save selections.
